The weight of one section of a cast-iron battery. Cast iron battery section weight

To calculate the heating system, it is necessary to take into account many different parameters. One of them is the weight of heating appliances. For example, you want to install a classic cast-iron radiator, which consists of 4-10 sections. To calculate the mass of the entire heating system, you must first make a calculation with respect to one cast-iron battery, which will ensure its installation reliability.

About cast iron batteries

The cast iron radiator belongs to the classics of the genre. It has been used for more than 100 years and not a single modern model is still capable of completely ousting it from the market. Cast iron radiators are in demand due to the characteristics of the material itself.

Important advantages of cast iron are:

1. corrosion resistance,
2. long service life,
3. Undemanding to the quality of the coolant,
4. Excellent heat transfer
5. Undemanding in application.

Everything can't be so smooth, and two flaws are still there.

• One lies in the mass. How much does a cast iron battery section weigh? Weight 1 section cast iron radiator is approximately 7.5 kg. Thanks to simple deductions, we can conclude that a standard battery of 7 sections will weigh 52.5 kg. To provide comfortable temperature in a room, one section of the heating element is usually not enough. Based on these circumstances, in order to ensure the reliability of the structure, it is necessary to think over ways of attaching the radiator elements to the wall. Let's do the calculation with an example. The Soviet model MS 140, which is still on the market, has a considerable mass - 7.12 kg. The volume of its one section is 1.5 liters of water, the total mass is 8.62 kg. The thermal power in this case is approximately 170 watts. How many sections are needed to heat a room of 20 m2? If it is necessary to heat a room of 20 m2, then 12 sections will be required, then the mass will be 85.4 kg, plus water - 103.4 kg.
• The second negative point of cast iron is its fragility. Therefore, in order to carry out the transfer of a product with a large mass and its fastening, it is necessary to do all manipulations with it as carefully as possible, preventing the slightest impact in order to avoid microcracks invisible to the eye. Since in the process of working with the inevitable increase in pressure in the heating network, the resulting cracks will begin to increase, which will end in radiator leaks.

Basic characteristics of a classic radiator

A standard cast iron battery consists of 4-10 separate sections. Its size depends on the choice of the thermal regime in the room and architectural features Houses.

Despite the difficulties encountered when installing a heavy cast iron heating radiator, this is still not considered the main problem. The main task is to fulfill correct installation batteries. To implement it, it is not enough to know only the mass of the product, it is necessary take into account the following points:

• Distance between axles. Standard models may have 350 or 500 mm. Batteries with a large height are characterized by proportional dimensions between the axes.
• Depth. Standard sizes 92, 99, 110 mm.
• Section width. The sizes are in a slightly larger range - 35 - 60 mm.
• Section volume. This is the amount of coolant that is needed to completely fill the radiator element. The volume depends on the size of the section. Average values ​​range from 1 to 4 liters.

An important problem with installing a classic cast iron battery is that it is only designed for wall mounting. At the same time, most modern houses are made from porous materials , such as aerated concrete, foam concrete, as well as SIP-panels with foam filling. These walls need a special fastening of a complex design with multi-point fixation, which is unlikely to be to your liking.

Modern models of heating radiators

For mounting on walls, various manufacturers have developed new models made of gray cast iron, their weight is much less than the old classic samples. For example, let's describe the Czech heating radiator Viadrus STYL 500. How much does 1 section of this heating radiator weigh? And how much will the mass of the whole structure be?

Weight of 1 section is 3.8 kg, water holds 0.8 liters, so the mass of one section of the radiator with water will be 4.6 kg. With a heat flow of 140 W, 14 sections will be required to heat a room of 20 m2, respectively, by weight, 64.4 kg with water will come out. Thus, this indicator differs downward by 40% than that of the classic MS 140 sample. If this value is divided into two parts (32 kg each), then we can conclude that installation on walls made of modern materials, including porous concrete, it is quite possible to implement without additional fasteners.

Even more lightweight construction developed by Russian manufacturers. Their heaters are offered under the EXEMET brand, the MODERN model has the following weight characteristics:

One section from this manufacturer weighs 3.2 kg, heat dissipation is 93 watts. To heat a room of 20 m2, 22 sections are required, then the total mass will be 70.4 kg. These parameters are not bad, especially considering that the company produces models with possible installation on the floor.

vintage model

A few words about the vintage cast iron battery. Its weight exceeds the Soviet model, which can reach 14 kg. These heaters outwardly very much resemble the old ones, which were installed in the distant 19th century in residences and estates.

The EXEMET FIDELIA model weighs 12 kg, heat dissipation is 156 W, the total weight of the device for our example is simply monstrous - 154 kg. The complex issue of installation is irrelevant here, since the first and last sections equipped with legs to place the device on the floor.

So, in order to provide the heating system with uninterrupted service, one cannot ignore such important indicators as the weight and volume of the battery section. Due to the correct calculation of the load on the fasteners, you can count on the reliability of the installation and the long-term operation of the device.

Despite the greatly expanded last years range of heating appliances, classic cast iron radiators are still common and in high demand. And although these devices have many advantages in comparison with competitors, a number of nuances must be taken into account when choosing. Among the most important of them is the weight of a cast-iron battery (with 1 section or more). This parameter is of key importance at all stages from acquisition and installation to operation.

Description of cast iron radiators

Cast iron heating appliances have been popular and in demand for two centuries. With the advent of more modern products made from steel, cast iron batteries began to be called old-style radiators. However, the status of obsolete devices does not prevent such models from occupying a significant share of the market for space heating devices.

The novelties that filled this niche did not succeed in completely replacing the type of cast iron batteries. The latter are worthy competition to modern models. The features that they possess endow them with many advantages.



Production and design

For the manufacture of 1 section, or, in other words, 1 fin of an old-type radiator, cast iron is used as a material. Regardless of the size of the future battery, all sections are produced separately.

Then required amount finished sections by means of nipples is assembled into a single structure. The joints must be sealed with paronite or rubber gaskets.

Cast iron radiators



Varieties and their differences

The existing range of cast iron radiators is huge. Models differ from each other both in appearance and in technical characteristics. The main difference is the size. Cast iron radiators vary in width, height and depth.




The battery width is the number of sections (ribs). The value of this parameter is directly related to the area of ​​the heated room. The larger it is, the more sections will be required to heat it, and the longer the radiator will be.

Height, or center distance, has a wide range. The same applies to such an indicator as depth. Typically, model parameters fluctuate:

• in height - from 30 cm to 150 cm;
• in depth - from 50 mm to 140 mm.

Deviations from these standards are also possible. The required values ​​​​are determined depending on the needs and features of the interior of the room.

In addition to dimensions, batteries differ in the nuances of design and structure. For example, channels that fill hot water, are of two types:

• round;
• elliptical.

Advantages of the models

The popularity and demand for cast-iron radiators is due to their advantages that they do not have. modern models heating appliances.

One of the main advantages of cast iron batteries is long term exploitation. Manufacturers claim that the life of the device is 50 years. But if the radiator is properly looked after, it will last much longer than the specified period.

Another important characteristic is strong pressure resistance. The battery can withstand both 9 and 12 atmospheres without any problems. This determines the protection of the device from water hammer. It is for this reason that cast iron radiators are traditionally installed in multi-storey buildings with centralized system heating.

In addition to resistance to pressure, such devices have excellent endurance in relation to high temperatures. The device is able to withstand heat from 100 to 130 degrees Celsius.

Enough equipment unpretentious in operation. The cast iron radiator resists well both external and internal influence aggressive environment, which has a provoking effect on the corrosion process. Thanks to these and other characteristics, such models do not need frequent cleaning, which is required by other varieties.

It should be noted that 1 section produces heat with a power of up to 160 kW. But the level of heat generated depends not only on the number of sections that make up the battery. Cast iron appliances are capable of distributing heat to other objects through infrared radiation. Therefore, in fact, the heating power that only one radiator gives is multiplied several times.

The design of the device makes it easy to modify if necessary. In addition, you can initially select a device with the desired power. And also among the advantages of cast iron models should be noted their reasonable cost.

Device Disadvantages

Of course, these devices are not perfect and have some drawbacks. Compared to the number of advantages, these disadvantages are insignificant, but they should still be taken into account.

Cast iron radiators put a lot of pressure on the pump, since for each warm-up cycle it must pump a large volume of water. Another drawback is associated with such an amount of water - it takes quite a long time to warm up the room.

The disadvantages of many include the appearance of cast-iron appliances. Manufacturers took this into account, but in the process of eliminating one minus, another arose. Today, on the market of heating devices, you can find radiators with an attractive look - there is a beautiful pattern on the surface of the sections. But the price of "decorated" models is much higher than that of simple batteries. That is, the solution to the problem of external clumsiness led to an increase in cost. When purchasing a device, you will have to choose - either appearance or price.

One of the main disadvantages is considerable weight cast-iron heating radiators - products made from other metals are noticeably lighter. Because of this feature, the device is very difficult to transport and install. The labor-intensive process of installing heating equipment requires workers to have professional skills. A person who does not have experience in installing just such models is better not to take on this matter.

Cast iron radiator - pros and cons! REVIEW! Characteristics

Mass of the heating device

Sections of an old-style cast-iron battery weigh differently. This is due to the fact that the models on the market have significant differences in parameters. The mass of the heating radiator directly depends on the configuration of the device as a whole, its dimensions (that is, the number of ribs, center distance and depth), as well as on the wall thickness of the sections.

There is no absolutely exact information about the mass of a device made of cast iron - such a value can only be indicated for each specific model separately. But it is possible to give average or closest values.

The main value that you should know is the weight of a cast-iron battery with 1 section, since this indicator allows you to calculate the approximate weight of a radiator with a large number of fins. Classic standard model with single section weighs about 7-7.5 kg(for comparison, it is difficult to find 1 section weighing more than 2 kg among equipment made of other metals).

Now, based on this average, you can calculate, for example, how much a cast-iron battery of 10 sections weighs. Thus, the approximate mass of this heating equipment is 70-75 kg. It should be remembered that such calculations are only indicative - the real value may turn out to be different (both up and down).

Device types by weight

It is customary to divide radiators into standard and non-standard. The mass range of 1 rib in the first, with their characteristic center distance of 300 mm and 500 mm, is 4-5.7 kg and 5.5-7.2 kg, respectively. For non-standard ones, 1 section can weigh on average from 3.7 kg to 14.5 kg.




It is possible to apply another classification. Cast iron models currently produced by manufacturers and popular with consumers can be divided into three main types:

• classic (or old-style);
• vintage;
• lightweight.

Classic radiators are easy to recognize by name. They are always denoted by the letters "MS", after which two numbers follow through a dash - the depth of the sections and the center distance. One of the most common standard models:

• MS - 140 - 500;
• MS - 140 - 300.

The mass of 1 section of the first is usually 7.1 kg, and the weight of 1 rib of the second is 5.7 kg.

Representatives of the vintage type are now at the peak of popularity, despite the fact that these are the heaviest radiators of all. The mass of 1 rib can be 12 kg. Due to their heavy weight, vintage devices are classified as floor standing devices. These batteries look very attractive. They are produced using art casting technology, which makes them not just heating equipment, but a real decoration of the interior of the room.

Lightweight models are made of gray cast iron. This is the most modern variation of cast iron radiators, but so far it is also the least popular variety.

Influence of equipment weight

As already noted, the weight of the cast-iron radiator section and the battery as a whole predetermines the principles of installation and the complexity of installation. Only starting from this parameter, it is possible to determine the required carrying capacity of transport for delivery and a sufficient number of loaders and workers.




The heavy weight of the batteries causes some difficulties during installation and installation. It is impossible to carry the equipment alone - only two people and with the utmost care and caution. Despite its mass and apparent strength, cast iron is a rather brittle material. Even from a light blow, microcracks can occur on it. Subsequently, already under the influence of the coolant, these microdamages will increase, which will result in depressurization of the heating equipment.

Another problem is the correct and reliable installation batteries. The sturdy fixing wall mount is quite difficult to mount.

But if the wall is based on light porous blocks, this is almost impossible to do. Under such circumstances, it will be necessary to establish heating device on the floor.

When it comes to the purchase and installation of cast iron heaters, the very first association is the heavy Soviet radiator and all the difficulties of moving and installing that are associated with it. In fact, there are a lot of varieties of these devices, their mass varies over a wide range. Our goal is to convey how much a section of a cast-iron battery of various configurations weighs and solve the problems associated with this.

classic batteries

Indeed, 1 section of the classic Soviet battery MS 140, which is still commercially available, has a considerable mass - 7.12 kg. If we take into account the fact that the volume of one section of the MC 140 cast iron battery is 1.5 liters of water, then the total mass will be 8.62 kg. Knowing that the thermal power of each section is approximately 170 W, then for an average area of ​​​​20 m2, 12 such sections will be required, which will be 85.4 kg in weight, and 103.4 kg together with water.

You can say that it is not necessary to install one large device, but you can divide it into two, and you will be right. Nevertheless the net weight of old-style cast-iron batteries would then be 43 kg that, according to labor protection rules, it is not allowed to lift one person, an assistant will be required.

The second problem is that classic radiators are only for wall mount, and the vast majority modern houses It is built from porous materials, at best, from aerated concrete or foam concrete, at worst, from SIP panels filled with foam. Such walls will require special mount for cast iron radiators of complex design with fixation at many points, which is unlikely to please you.

Modern cast iron radiators

For wall mounting, there are new products made of gray cast iron from various manufacturers, whose weight is much less than the traditional MC 140. For example, the Czech heating radiator Viadrus STYL 500, shown in the figure.

Its characteristics are as follows: the mass of 1 section is 3.8 kg, the water capacity is 0.8 l, for a total of 4.6 kg. With an available heat flux of 140 W, our room of 20 m2 will require 14 pieces, which will be 64.4 kg in weight along with water. This indicator is 40% less than that of the MC 140, and dividing it into 2 parts (32 kg each device), it becomes clear that it is possible to install cast-iron radiators on walls made of porous concrete without special additional tricks.
Offers an even lighter design Russian manufacturer, which sells its heating appliances under the EXEMET brand, namely the MODERN model.

Here, one section of the radiator weighs only 3.2 kg with a heat output of 93 W; in a room of 20 m2, 22 sections with a total weight of 70.4 kg are needed. This indicator is also quite good, especially considering that the company manufactures these batteries with the possibility of floor installation.

It is impossible not to say a few words about such a product as a vintage cast iron battery, whose weight is even larger than the Soviet MS 140 and in some cases reaches 14 kg. These heaters, by their appearance, resemble the old ones, installed in residences and estates in the distant 19th century.

The EXEMET FIDELIA model shown in the figure has a weight of 12 kg with a heat output of 156 W, which makes the total weight of the cast-iron radiator for our example simply monstrous - 154 kg. But as you can see in the image, here the installation issue is solved differently: the first and last sections have legs for placing the heater on the floor.

Conclusion

Nowadays, it is possible to choose a cast-iron heating device in relation to different conditions installation, including weight. Thanks to floor installation too heavy vintage batteries do not even need brackets for mounting, except perhaps as an additional fixation to the wall.

What is the weight and volume of a cast iron battery?

When it comes to buying cast iron, an association immediately arises with heavy old appliances that cannot surprise you with anything other than their dimensions. But are such associations justified, or are they just stereotypes? Let's figure it out and find out what is the weight and volume of one section of the cast iron radiator.

Old style batteries

There are two types of old-style cast-iron radiators:

• classic;
• vintage.

One section of a classic cast iron battery weighs an average of 7.1 kg. In practice, slight deviations in the direction of increase are possible - up to 7.5 kg, depending on the height of the device. This is the mass of the hollow section, but together with the coolant, its weight will be 8.6 kg: the volume of the old-style radiator section is 1.5 liters.

The thermal power of one cast iron section is approximately 170 watts. Thus, to heat a room of 20 sq.m. 12 sections will be needed, which will be 85 kg in weight, and after filling with coolant - 103 kg.

Advice. In order to avoid problems with the installation of the radiator, it is not recommended to buy a device with a net weight of more than 43 kg - it is better to install two 6 sections instead of one battery for 12 sections.

The second type of cast iron appliances is a vintage radiator. Its section weighs even more than the classic one - 12-14 kg. But the heat output of the device is lower - 156 W per section. The volume is the same - 1.5 liters per section.

Vintage cast iron radiator

Modern radiators

The weight of the so-called lightweight cast-iron batteries is on average two times less than the mass of classic ones and three times less than vintage ones. Naturally, other parameters, including volume and power, also differ:

• One section of a standard modern cast iron battery weighs from 3.2 kg to 3.8 kg. On average - 3.5 kg.
• The volume of the coolant is 0.8 l. The filled section weighs 4.3 kg.
• Heat output of the section - 140 W. For heating a room of 20 sq.m. You will need 14 sections. The weight is heating structure together with water will be 60 kg.

Advice. If you use two 7 sections each, that is, weighing 30 kg each, instead of one battery for 14 sections, you can do without additional clamps during installation - basic fasteners are enough for lightweight devices.

So, we have several types of batteries that differ in both weight and volume. So, if you want to see cast-iron radiators in your home, you always have a choice: from relatively light modern ones to unthinkably heavy, but spectacular vintage ones.

How much does a cast iron battery weigh: video

People of the older generation remember very well that during the period of mass housing construction in the 60s and 70s of the last century, exclusively cast-iron heating radiators were installed everywhere in new houses. And many of these batteries, having already served By century, or even more, they are quite coping with their task to this day. Interestingly, when attempts were made to massively transfer the construction industry to steel plate or panel radiators, it was perceived by the population without much enthusiasm. The owners of new apartments, having wintered with such "novelties", ruthlessly cut them off and looked for an opportunity to install "good old" cast iron. There were times when this even caused a rush demand, cast-iron batteries fell into the category of scarce goods, and it was not so easy to find them.

How did cast-iron batteries win such high confidence? The secret lies in the operational potential inherent in them. Let's take a closer look at such a battery, or, as it is correctly called, the MS 140 cast-iron radiator technical characteristics, varieties, advantages and disadvantages, basic installation rules. In addition, we will try to independently calculate how many sections are required for the battery so that it fully copes with the task of heating a particular room.

The main advantages and disadvantages of cast iron radiators MS-140

If you go to a specialized hardware store, you can see for yourself that wide choice modern heating appliances. The buyer is offered steel radiators various modifications - from panel to tubular, light aluminum with a very high heat transfer, the most technologically advanced and reliable bimetallic. Almost all of them have very original performance, which will easily fit into the interior of the living room.

So why are there many consumers who reject all new developments and still opt for cast-iron radiators?

• The undoubted advantage of cast iron batteries is their highest durability and reliability. Manufacturers estimate their service life at about 50 years. This is not an exaggeration at all, as practice shows that such heaters, with proper care, last much longer.

A vivid example of this is the record-breaking battery installed in one of the palace complexes of Tsarskoe Selo. It has been serving regularly for more than 110 years, and so far does not give any reason to doubt its reliability and make any replacement. But this is an officially confirmed fact, but in fact, it seems that in the houses of the old housing stock you can find radiators with more solid experience.

By the way, not everyone knows that the history of cast-iron batteries, in approximately the same form that has come down to us, originates in the middle of the 19th century, and it is in Russia. They were first cast in St. Petersburg back in 1855. The "father" of the cast-iron radiator is considered to be the Russian entrepreneur Franz San-Galli, the owner of the plant and at the same time a talented inventor in the field of water supply and heating. The first batteries were worn interesting name- "hot box" (heizkörper). And the technology of their casting, in principle, has not changed to this day - gray cast iron and special clay flask molds are used for this.

"Father" of the cast-iron radiator Franz San Galli and a monument in honor of the 150th anniversary of this device

To finish with a historical digression, one more eloquent fact can be mentioned. Have monuments been erected to many objects of human life? But the cast-iron radiator deserves such an honor! In commemoration of the 150th anniversary, in 2005, a monument - a bas-relief - was erected at the Samara State District Power Plant. Is this not evidence of the highest reliability of the cast-iron radiator and its undeniable popularity?

• The unpretentiousness of a cast-iron radiator to any heating systems is one of its most important advantages. And it consists of several parameters:

- Firstly, it is able to withstand very serious baric loads - for them, a line of 10 ÷ 12 atmospheres is considered quite acceptable pressure.

- Secondly, the operating temperature range - up to 130 degrees, allows them to be used in central systems with high pressure and coolant temperature.

- Third, cast iron sections batteries have wide internal cavities and channels. This is both a minimal risk of blockages and high resistance to water hammer, which is not uncommon in central heating systems.

- Fourth, cast iron casting practically immune to corrosion. This means that radiators are absolutely “not capricious” in terms of the quality of the coolant. It is no secret that the water circulating through the pipes of central heating systems is very far from clean, and its aggressive environment is simply contraindicated for many other batteries. But not for cast iron.

Summary - cast iron batteries are suitable for any central and autonomous systems heating without limitation.

• The high heat capacity of cast iron allows you to hold heat longer, effectively heat the room. Moreover, it is these batteries that, in addition to convective air heating, have the ability to give off heat with infrared radiation to the maximum extent, and this is a very significant help to the entire heating system. Remember the "hot" cast-iron batteries - even at a distance from them you feel warm. No other radiator can compare with them in this matter.
• Cast iron batteries MS-140 are a collapsible design. This allows you to set the number of sections required for a particular room, change it as needed, and replace the emergency unit.

• The price of such cast-iron radiators is quite affordable. Often, for reasons of economy, even used batteries are purchased by owners, which, after washing and proper sorting, will last for a very long time.

Some of the advantages are a kind of "double-edged sword". So, for example, wide channels - On the one side, good, but to fill them, much more coolant will be required. And the high heat capacity of cast iron predetermines a very significant thermal inertia of radiators. To bring them to a working state, much more energy consumption will be required, that is, the boiler at the start-up stage will work with a greater load, with virtually no pauses. True, this is compensated during operation - cast-iron batteries will remain hot longer even after the heating is turned off.

After the foregoing, one might get the impression that cast-iron radiators are practically devoid of serious shortcomings. However, this is not so - they also have very significant "minuses":

• For all positive qualities cast iron, it is a non-ductile, hard and brittle alloy. It does not like accentuated mechanical loads - it can simply crack. The lack of plasticity is also a big risk of damage during sudden temperature changes, the crystal lattice "does not keep up" with linear thermal expansion. For example, if the moderator suddenly gets into the battery warmed up to high cold water, then the walls of the section may crack. Similarly - and negative temperatures: if the battery is frozen, then with a very high degree of probability it will fail.

• The second important drawback is excessive massiveness. Even one section (with a center distance of 500 mm), not filled with coolant, depending on the specific model, it can weigh 6 ÷ 7.5 kilograms. Plus, a lot of connecting nipples and plugs. As a result, an average battery, say, only seven sections, can already give a load of about 50 kilograms. And if you add the mass of the coolant (and in each section it is another 1.45 kg), then the total weight already jumps over 60 kg. And after all, we are talking about a relatively small battery! What then to say about the assembly in 10 or more sections.

This feature significantly complicates the installation work - alone, without an assistant, it sometimes becomes an impossible task to perform them. In addition, powerful brackets or hooks are needed. And one more thing - not every wall structure is able to withstand such a load.

Have to think enough complex structures, with an emphasis on the floor surface or even with amplification back side of the wall.

True, some models of cast-iron radiators can be equipped with stand-legs, or they can be directly designed for installation on the floor - in this case, the legs become part of the structure (for example, on the extreme sections of the battery).

• Most of the radiators coming from factories have only a primer layer. This means that in order to give the batteries maximum aesthetics, you will have to paint them yourself, and this is not as easy as it might seem.

In addition, such repainting will have to be carried out regularly, at least once every 3 to 5 years.

In fairness, it must be said that some manufacturers still meet the needs of consumers, and their products go on sale after a cycle of multi-layer staining with persistent polymer paints or even powder coated. It is clear that such radiators are already significantly more expensive.

• A disadvantage similar to the above is that cast-iron radiators are often scolded for being unaesthetic, as says, "barracks" appearance.

To be honest, this is a very subjective question, that is, it lies in the plane of personal preferences. Steel panel radiators may also not shine with beauty, but someone does not like the too modern look. bimetallic batteries, which can be difficult to fit into some interior styles.

In the end, no one bothers to cover the radiators with a decorative screen (of course, so as not to worsen the efficiency of the heating system).

How to properly close the radiator grill

Installation decorative screen, boxes, gratings will help to cope with the problem of the unaesthetic appearance of the heating battery. How to correctly, so as not to reduce the efficiency of the heating system at home - read in a separate publication of our portal.

And some manufacturers also practice casting sections with decorative designs - on the walls of the radiator, original “antique” relief patterns are obtained.

Main technical characteristics of cast iron radiators MS-140

Now - about specific technical specifications various models of cast-iron radiators of the MS-140 series

What does the abbreviation "MS" itself mean - on this score, by the way, there is no consensus. There are versions of "modified standard", "Moscow standard", "metal sectional", "mounting sectional" and other options.

But "140" is quite certain value, specifically indicating the depth (distance from the rear to front side) of each section - 140 mm. Usually this name is accompanied by a second numerical value.

• For example, the abbreviation MS-140-500 indicates that this is a cast-iron radiator with a section depth of 140 mm and a center distance of 500 mm.

This is the most common a series that was used for installation in apartments of high-rise buildings during their mass construction. The average heat transfer power of such a section is about 160 watts.

MS-140 radiators can have different center distance - 500 or 300 mm

• But this series also includes radiators MS-140-300. As is clear from the classification name, they differ in center distance - only 300 mm. Such batteries were not so popular, but in some cases (for example, low window sills), they were used. Of course, their heat exchange area is significantly smaller, which is also reflected in the heat transfer power characteristic - only about 120 W from one section.
• MS-140-500 and another variety are produced. In them, both vertical channels of the section are connected on the outside by diagonally located ribs. Such finning sharply increases the area of ​​active heat transfer, and the power of the section increases to 190 watts.

True, such radiators are difficult to paint, and also require frequent cleaning. The area of ​​dust settling on flat surfaces ribs is large, and if they are very dusty, it is no longer necessary to talk about 190 W from the section - losses can be on the order of 30 ÷ 40 W.

The raw material for casting the sections themselves, as well as very often - deaf or through plugs, is gray cast iron (according to the classification - SCH -10). Couplings-nipples are made either from ductile iron (KCh - 30 - 6-F), or from steel (08 KP or 08 PS). The thread on the sections, nipples and external on the plugs is G1 ¼ʺ The through plugs also have a threaded hole G ¾ or ½ inch.

The tightness of the connecting nodes between the sections is ensured by ring gaskets. For their manufacture, a special heat-resistant rubber (PI or TTC), or paronite, is used.

A number of enterprises are engaged in the production of cast-iron radiators in Russian Federation and in neighboring countries. They all adhere, in principle, to the same technical standards, although battery performance may vary slightly.

Among the MS-140 cast-iron batteries on sale, the most common products are the products of the Novosibirsk plant OOO Dekart, the Nizhny Tagil boiler and radiator plant, and the company Santekhlit from the Bryansk region. The radiators of the Minsk Heating Equipment Plant and the Lugansk Casting and Mechanical Plant are in good demand.

Let's take a closer look at them.

Pig-iron radiators of the Plant of heating equipment, Minsk

The products of our Belarusian neighbors enjoy the widest popularity. Radiators of the Minsk Plant are always of high quality and interesting engineering solutions.

In addition to the usual forms, the product range includes radiators with legs for outdoor placement– this allows you to get rid of a complex and time-consuming hanging procedure

The designers of the enterprise are also trying to get away from the annoying forms. Thus, the production of cast-iron radiators has been mastered, structurally remaining the same MS-140, but having a smooth enameled front surface. In addition, options with artistic relief casting in retro style are also offered.

In a word, despite the seeming similarity of all cast-iron radiators, the buyer still has a choice.

The main technological methods of mounting cast-iron batteries MS-140

During the initial installation, the battery is assembled from the required number of sections. However, sometimes circumstances force the owners to either increase the radiator if its total power is clearly not enough, or, conversely, make it smaller. In addition, and in situations occur during operation when it is necessary to disassemble the battery, for example, to replace a failed section or for maintenance, cleaning or flushing.

Heating radiators require maintenance

The low quality of the coolant can lead to a gradual overgrowth of the channels inside the radiators. How to conduct it yourself - read in a special publication of our portal.

To fully understand how cast iron batteries are disassembled and assembled, it is necessary to understand the principle of connecting the sections to each other. Attention to the diagram:

Each section (item 1) has two G1¼" threaded sockets on each side, top (item 2) and bottom. The distance between their centers is the center distance, which is indicated in the product classification. Thread from horizontally opposite sides of the section opposite directions(left and right), while the upper and lower sockets on the same side must have the same thread direction.

Plugs (pos. 3) are installed on the end sides of the assembled battery. They can be through, with a threaded hole, or blind. Depending on the installation side of the plugs, they can also have a right-hand or left-hand thread. The diameter of the internal morning thread is G ½ or ¾ inch, always only the right one - pipes, shackles or fittings are connected (packed) here for further insertion into the heating circuit, or taps for air release.

Sections are interconnected with nipples (pos. 4). This part is a cylindrical coupling with two counter-directional threaded sections that converge in the center of the nipple. A gasket (pos. 5) must be installed between the sections.

On inner surface The cylindrical nipple has special projections (protrusions) (pos. 6), which are necessary for engagement with splines (pos. 8) of the mounting key (pos. 7). The wrench itself may have a welded T-handle for applying force, a loop for inserting a lever, or a faceted bar surface for gripping it with a gas wrench.

1 - nipple (protrusions for the key are clearly visible).

2 - O-rings, paronite (as shown) or rubber. They are installed between the sections and under the radiator caps.

3 And 4 - blind and through plugs. There are left and right.

Installation of a heating battery from separate sections is shown in the diagram below:

For installation work it is best to prepare yourself a comfortable platform, for example, on spacious workbench or on the floor. It is recommended to cover the surface with a sheet of plywood so as not to scratch the ribbed edges of the sections.

How the sections are assembled into a single battery - schematically:

1 - Gaskets are put on the nipples so that they stand in the center, in the place where the two threaded sections converge. The sections are located coaxially, the correctness of their mutual placement must be checked - at the junction, the thread in the sockets must be counter-directed. Usually the manufacturer puts brand marks on the sections - this will help to avoid mistakes, since these marks should take a uniform position.

2 - Through the section window, an assembly key is inserted so that its working head with slots enters the nipple. It is best if you have two keys at your disposal - it will be easier to work this way, alternately moving from one to the other. The sections assembled together are brought together and pressed against one another. By rotating the key, the nipple is rotated - at the same time, it is necessary to ensure that it simultaneously "cashed in" on both sections. A similar operation is done on the opposite side. Then, alternately, avoiding distortions and wedging, the nipples are screwed in, simultaneously pressing the sections one to the other. Twisting is carried out until the tightest contact in the connecting knots. Experienced plumbers "by eye" are able to determine the required effort during assembly. The manufacturer in the technical documentation indicates that the moment of application of force during tightening should not exceed 15 kgf × m so as not to deform the thread and protrusions on the inner surface of the nipple.

3 - after mounting the first two sections, you can attach the third in the same way, and so on, until the required battery is fully assembled.

4 - it is quite possible to connect the battery and "fragments" - several sections pre-assembled into blocks. The only requirement is that the length of the mounting key rod is enough. By the way, it is in this way that they usually dismantle and replace the failed section if it is located somewhere in the center of the battery. There is no need to sequentially disassemble the entire radiator - dismantling is carried out only at the right point.

It is clear that the dismantling is carried out in the reverse order. However, there are situations when corrosion has "eaten" the protrusions on the inner surface of the nipple, and it is not possible to unscrew it. There is only one way out in this case - carefully cut with a “grinder” at the location of the gasket between the sections, and then heat the remaining fragments of the nipple and unscrew them from the sockets.

When reassembling after disassembling the radiator, of course, it is worthwhile to carefully evaluate the integrity and "survivability" of the nipples - they are inexpensive, and it would be reasonable to replace "doubtful" parts with new ones.

How many sections of the MS-140 radiator will be required to heat the room?

There was one more unanswered question - how many sections are needed in order to ensure full heating of a particular room?

There is a simple rule that 100 V is required for heating t t heat energy per square meter tr square footage of the premises. This means that it will not be difficult to calculate the amount - the area is multiplied by 100 and divided by thermal power one section of the selected radiator model.

For example, a room of 18 m² requires, respectively, 1800 kW of thermal energy. So, if a typical MS-140 with a specific power per section of 160 W is selected, the required amount will be 11.25. The value is rounded up to the nearest integer. Total - 12 sections.

The calculation is indeed simple, but very inaccurate. The fact is that 100 W / m² is a very average value, and in different climatic conditions, of course, does not fully reflect the need for thermal energy - somewhere this may not be enough, and in the southern regions such power will simply be excessive. In addition, the features of the building, the location of the room on the cardinal points, the size and number of windows and their design, the degree of insulation of the walls and ceiling are of considerable importance. Even the method of inserting batteries into heating circuit- and he is able to affect the heat given off by radiators.

Therefore, we suggest the reader to use a special calculator, which already contains most of the criteria affecting the required heating power. Enter the requested values ​​- and immediately get the result, depending on the selected type of cast iron radiator.
