How much does one section of cast iron battery weigh

How much does a cast iron battery section weigh

Cast iron radiators have squeezed the market under the influx of modern developments in the field of heating devices, but they continue to be serious competition to the novelties. When choosing, it is important to consider the weight of the cast iron battery, since this parameter affects the complexity of installation and installation principles. In this article a master plumber will tell you how much a cast iron battery section weighs.

Cast iron radiators can vary in width and height. The width depends on the number of sections, which, in turn, is determined by the area of the heated room. The height usually ranges from 35 centimeters to one and a half meters. Batteries can also vary in depth. Most often this figure has a value of 50 to 140 centimeters and is chosen depending on the interior design room.

During installation the sections are made into one structure with the help of nipples and special radiator tongs. The joints are sealed with rubber or paronite gaskets. Channels filled with hot water can be round or ellipse-shaped.

Among the advantages of cast iron batteries, it is worth noting the following:

  • Longevity: the manufacturer’s stipulated service life is 50 years, but with proper care, it can last much longer;
  • Resistance to pressure of 9-12 atmospheres, which provides protection against water hammer (that is why cast-iron radiators and are commonly used in high-rise buildings with central heating);
  • Temperature endurance from 100 to 130 degrees;
  • The ability to produce a single section of power up to 160 kW;
  • Resistance to the effects of aggressive environment, provoking corrosion;
  • No need for frequent cleaning;
  • The ability to spread heat to other objects due to infrared radiation;
  • Simple modification;
  • Possibility to install the radiator of necessary power;
  • Affordable cost.

In the application of cast iron radiators noted and disadvantages:

  • Heavy weight, which makes it difficult to transport and install;
  • Complexity of installation, requiring professional skills;
  • Long heating time of the room due to the large volume of water;
  • High load on the pump, which has to pump a significant amount of water per heating cycle.

The disadvantages of cast iron radiators can also include the design uniformity, however, it is this indicator that is currently progressing and developing.

An elegant design of cast iron, of course, can not make, but now manufacturers produce batteries with a beautiful pattern on the surface. Such devices fit well into the interior, although they cost considerably more than simple equipment.

The question of how much does one cast-iron section weigh, interests everyone who has decided to buy radiators. Average weight of a standard radiator with 6 to 10 fins is 50-58kg. The classic sectional battery weighs 7.5 kg per cell.

A more specific figure depends on the height, configuration and wall thickness.

Currently, manufacturers offer lightweight versions of batteries made of gray cast iron, but radiators of the old type are still widely used.

There are also modern heavy installations, for example, especially popular now are considered vintage radiators made of cast iron. Models are floor units, made by the technology of artistic casting, the weight of a single link can weigh up to 12 kg.Cast iron batteries of the old type are unpretentious in operation. They can be recognized by their name: the designation “MS” is an indispensable “companion” to the names of older models, followed by a dash, the first of which indicates the depth of the sections, and the second. the distance between them.

Casting Calculations: Determining the weight of metal needed for casting

Radiator MS-90 can look as four- or seven-section construction. These batteries are ideally suited for Russian thermal networks. Installation in industrial and residential premises is possible.Technical characteristics:

  • Heat output. from 130 W;
  • Width of one section. from 7,1 to 9 cm;
  • Height. from 58. 58,1 cm;
  • Depth. from 9 cm;
  • Volume. 1,15. 1,45 l;
  • Weight of 1 section. from 5.48. 6.5 kg;
  • The distance between the axes. from 50 cm;
  • Temperature. up to 130 degrees;
  • Working pressure. 9. 12 atm.

Sectional radiators MS 140 is the only model that has “survived” to this day from the Soviet Union. Considered one of the most popular. Applicable in rooms with a low window sill.Specifications:

  • Heat output. from 130. 160 W;
  • Width of one section. from 9,3. 6,65 cm;
  • Height. from 38,8. 58 cm;
  • Depth. from 14 cm;
  • Volume. 1.11. 1.45 liters;
  • Weight of one section. from 5,4. 6,65 kg;
  • The distance between the axes. from 30. 50 cm;
  • Temperature. up to 130 ° C;
  • Working pressure. 9. 12 atm.

Among the pluses of old-style radiators is worth noting:

The disadvantages still include the heavy weight and unpresentable appearance.

In Russia, the production of cast iron batteries was launched not long ago, previously the radiators were supplied from Europe and China. However, until now, imported designs are considered of higher quality, however, and they cost much more.

The weight of the sections of foreign batteries depends on the manufacturer. For example, the mass of a popular Czech model Viadrus STYL 500 is 3.8 kg, and the weight of the sections of models of the Chinese firm Konner ranges from 3.5 to 4.75 kg (depending on the individual heat emission).

A well known Russian brand is EXEMET, which produces MODERN radiators, one “tooth” of which weighs 3.3 kg.

Modern models look much more attractive: they can have a flat front panel and a flat surface. Some units are fully ready for operation, while others require painting.

Designing the heating system it is required to calculate the weight of the radiator and the required number of sections in the radiators. Calculations are made on the basis of the capacity of one section of the heater (for the classic cast-iron product it is 170 W) and the thermal calculations of the room.To calculate the required number of sections and the total weight of the cast iron radiator, you should consider the area and heat loss of the room, which depend on the characteristics of the materials from which the walls are built, the presence of insulation. You also need to pay attention to the number of windows and type of window systems.

For a panel house the optimal value of heat flow is 0.041 kW/m3, for a brick house. 0.034 kW/m3, for buildings with insulated walls (regardless of the material from which they are erected). 0.02 kW/m3.

Given the considerable weight of one section of cast iron radiator, the number of links in a standard radiator varies from 4 to 10. In a large room it is more convenient to install two or three heating units in 4-5 sections instead of installing one extremely heavy radiator with a number of links more than 10.

Thus, cast iron radiators are the most heavy version of the heating system, which creates installation difficulties, but, despite this, cast iron radiators are the best devices to maintain heat in the apartment, time-tested. The equipment does not require special care, and the heavy weight and complexity of installation is compensated by long service and performance.

How much does a cast iron radiator weigh. weight of radiators from different manufacturers

To have information about how much a cast-iron heating radiator weighs, it is necessary for a number of reasons. For example, if radiators are purchased for installation in an entire private home, you need to calculate the carrying capacity of the vehicle transporting the radiators, as well as determine the number of movers who will carry them into the house.

To clarify the weight of cast-iron radiators of older models and modern counterparts made of other materials:

  • One section of standard cast iron radiators with a center distance of 500 millimeters weighs 5.5-7.2 kilograms, and with the center distance of 300 millimeters. from 4.0 to 5.4 kilograms;
  • weight of non-standard cast iron radiators is from 3.7 to 14.5 kilograms;
  • a section of aluminum battery at 500 millimeters spacing weighs 1.45 kilograms, and at 350 millimeters. 1.2 kilograms;
  • bimetallic devices with the distance between the axes equal to 500 millimeters weigh 1.92 kg / section, and at 350 millimeters. 1.36 kg / section.

When carrying out repairs and replacing heating equipment in the house, its owners are important to know how much an old cast-iron radiator weighs, in order to decide whether you can independently remove the old multi-section radiator to the street, because you need to calculate your own strength. But there is no such data.

The reason is that there are different models in operation. They have the same purpose, but different weight. In addition, the domestic market sells devices that differ in size and variety of shapes.

To date, for example, the names of traditional cast iron batteries are more than a few dozen, and models, made in designer style, and it is difficult to count. At the same time, such parameter as the weight of one section of the cast iron radiator differs greatly.

Advantages and disadvantages

Consider the main advantages of cast iron batteries:

  • Cast iron systems are durable and have a lifespan of 50 years, but with proper care they will last much longer. It is known to everyone and proven by time.
  • Withstand pressure of 9-12 atmospheres, which reliably protects the batteries from water hammer. That is why they are installed in multi-storey houses with central heating.
  • Easily withstand temperatures from 100 to 130 ° C.
  • One section can produce a thermal capacity of up to 160 kW.
  • Cast-iron radiators, unlike all others, are the most resistant to the effects of aggressive environment causing corrosion.
  • Have wide ducts, which also protects the batteries from water hammer, and does not require frequent cleaning.
  • Infrared radiation, which only cast-iron radiators have, is able to transmit heat to other objects. It makes the room retain heat longer after heating.
  • Easy to modify, making it possible to install a battery of the desired capacity. If necessary, it can be removed and increased, or decreased. For example: an old style cast iron radiator usually consists of 8-10. The larger the area to be heated, the more prefabricated heating parts are needed. So, for the desired thermal effect and comfort, in a room of 14 sq.m, only 4 sections are needed, which can be done by the usual and simple division of sections.
  • Affordable cost.

But the disadvantages of using cast-iron heating radiators are also swept up:

  • The main disadvantage. very heavy. So, the weight of one section without water reaches 7.5 kg. On average, set from 6 to 10 ribs, and weighs 50-58 kg.
  • Labor-intensive installation that requires special skills.
  • Low heat output due to high heat capacity. But at the same time, after complete disconnection, it contributes to a longer preservation of heat.

Cast iron radiators MS-140/500. technical specifications

Despite the fact that technology is not static, and new samples of heating equipment appear in the market every year, the good old batteries made of cast iron still occupy their niche and are still manufactured by domestic and foreign companies. In this article, the master plumber will tell you about the technical characteristics of the cast iron radiator MS 140/500.

Advantages and disadvantages of cast iron radiators MS-140/500

Traditional cast iron radiators are one of the most reliable heating devices, so they are still not superseded by modern counterparts from the market. The history of cast-iron radiators, approximately as it has come down to us, begins in the middle of the XIX century, and it was in Russia. They were first cast in St. Petersburg back in 1855. The “father” of the cast-iron radiator is generally considered to be the Russian entrepreneur Franz San Galli, the owner of the factory and at the same time. a talented inventor in the field of water supply and heating. The first batteries had an interesting name. “hot box” (heizkörper). And the technology of their casting, in principle, has not changed to this day. for this purpose they use gray cast iron and special clay molds.

Characteristics of cast iron radiator MC 140/500 are determined by the requirements of GOST 8690-94. Products corresponding to the state standards are notable for their durability, strength, anti-corrosion resistance. They are used in systems of steam heating of any structures practically without restrictions: in private houses, country cottages, apartments in apartment buildings, administrative offices, public buildings, industrial, warehouse, retail space. Equipment is designed for operation in moderate and cold climate.

The advantages of cast iron batteries include:

  • Low chemical activity, which ensures long service life in our networks. Officially the warranty period of 10 to 30 years, and operation life. 50 years or more.
  • Low hydraulic resistance. Only radiators of this type can stand in systems with natural circulation (some still put aluminum and steel tubular).
  • High temperature working environment. No other radiator can withstand temperatures higher than 130°C. Most of them have the highest limit of 110°C.
  • Low price.
  • High heat output. All other cast iron radiators have this characteristic in the “disadvantages” section. Only in the MS-140 and MS-90 the heat capacity of one section is comparable to aluminum and bimetallic. For the MC-140 heat output 160-185 W (depending on manufacturer), for MC 90. 130 W.
  • Not subject to corrosion when the coolant is drained.

Some properties are a plus in some circumstances and a minus in others:

  • High thermal inertia. While heating the section MS-140, may pass an hour or more. And all the time the room is not warm. But on the other hand it is good if the heating is turned off or a usual solid fuel boiler is used in the system: the heat accumulated by the walls and water keeps the room temperature for a long time.
  • Large cross-section of ducts and manifolds. Because of the large cross section in one section “fits” more than a liter of coolant. And it must be “driven” through the system and heat, and this is an extra cost for equipment (a more powerful pump and boiler) and fuel.
  • Large weight. Weight of one section with 500 mm center distance from 6 kg to 7.12 kg. And since you usually need 6 to 14 pieces per room, you can calculate what the mass will be. And you have to wear it and hang it on the wall. This is another disadvantage: difficult installation. And all because of the same weight.
  • Brittleness and low working pressure. Not the nicest characteristics. For all their massiveness, cast iron products must be handled with care: on impact, they can burst. The same brittleness results in a working pressure of 9 bar, which is not the highest. Compression. 15-16 atm the joints of which are sealed with rubber gaskets. The service life of the gaskets is considerably shorter than that of cast iron. In order to avoid leaks after several years of operation, the failed gaskets must be replaced.
  • Tendency to slagging of internal surfaces, which with time results in decrease of heat emission.
  • Appearance of these radiators is not refined enough, the surface requires painting. All sections are only primed.

Technical characteristics of radiators MS-140/500

MC group radiators belong to the category of sectional radiators. they are assembled of separate sections.

The sections are joined into a radiator using inter-sectional gaskets.

One section is pressed to the other by means of a nipple.

The ends of the radiator are closed with plugs, which can be shut-off and cap plugs.

Sections are cast in gray cast iron with graphite additives. Some parameters of the radiators MC 140 may slightly vary in the models of different manufacturers.

And now it is time to testify the technical characteristics of MC 140/500:

For example, the model MC-140-500-0,9-7 names radiator with a depth of 140 mm, the axial distance of 500 mm, the limiting pressure in the system of 0.9 MPa, with the number of individual blocks in the radiator equal to 7.

  • Installation of heating equipment should be entrusted to organizations specializing in the field of construction and installation work, which have the appropriate license. With the number of sections of less than 10 can be done in any way. bottom, top, diagonal. If the number of sections exceeds 10 it is recommended to connect diagonally: water inlet upwards and outlet downwards.
  • Before installing the radiator a hydraulic test should be performed to check the integrity of the device, the tightness of gaskets, the strength of nipple joints. For this purpose, a hydraulic test at 1.5 MPa is performed. If you find leaks due to nipple joints loosening, they must be retightened and tested again.
  • If the number of sections in a radiator is changed (increased or decreased), only gaskets specified by GOST 1412 should be used. After the radiator is assembled, check the strength of intersectional connections.This is done in a standard way. hydraulic testing under high pressure of 1.5 MPa, exceeding the maximum allowable loads. The precast should not leak or allow air bubbles to enter during testing.
  • After completing installation work is pressurized the entire water heating system, based on the results of which is an act of commissioning the facility.

But knowing the benefits and technical features of the appliance is not enough. Before you make a purchase, find out how many sections you need to provide a comfortable temperature in your home.

Accurate determination of the number of sections in the radiator heating is a long thing. You need to consider the region, the wall material, what are the windows and doors, how many windows in the room, what their area, whether the room below is warm or cold, etc.д. If you need a method of exact calculation, see here, but approximately can be calculated based on the area of the room. It is believed that on average 100 Watt of heat is needed to heat 1m2 of floor space. Knowing the area of your room, you determine how much heat you need: multiply the area by 100 W. Then divide by the heat output of the chosen model of radiators.

For example, in a room of 12m² we put a MS-140M-500-0.9. The heat output of the section is 160 W. Calculation:

  • Total heat required for 12m² 100W = 1200W
  • How many sections 1200 W / 160 W = 7.5 pcs. Let’s round off (always upwards. let it be warmer) and get 8 pcs.

Radiator MS 140 refers to the category of thin-walled equipment, so in order to maintain the integrity and prevent cracking, throwing and dropping the product is prohibited.

Equipment can be transported by any mode of transport provided it is protected from mechanical damage, falls, atmospheric precipitation.

The cast iron products should be stored in a dry room under a roof or shelter. Temperature conditions of the storage room. from.50°C to 50°C. Humidity at 15°C: 80%, at 25°C: up to 100%.

Acceptable ways of storing radiators are stacked up to 1.5 m high or in bundles, no more than two above the other.

Loading, moving, unloading stacks or packages can be done mechanized by forklifts or cranes. The packaged goods to be moved must be firmly secured on a pallet.

In the story. Recommendations for transporting, assembling and disassembling cast iron radiators MS-140

So, the cast iron radiator MS 140/500 can be safely installed in their homes. They are slightly inferior to the technical characteristics of new devices, but the price is their advantage. On top of everything else, they have a long trail from the past, proving their suitability throughout the 20th century, both in our country and abroad. The main indicator was a long service life.
