Cast iron radiators, ribbed - photos, reviews, device

The finned tubes are equipped with metal fins, due to which their outer surface is increased. This leads to an increase in the efficiency of heat transfer by one and a half times. Ribbed products are used in industry and in everyday life. They are used to equip heat exchangers and coolers, heating systems, industrial refrigerating chambers, metal communications.

Finned tubes - products with special properties and characteristics

A few words about the design

Pipes with metal fins do not differ in terms of the overall structure, but the differences lie in the details - the shape of the petals and the ribbing coefficient.

The pipe consists of two parts.

The foundation. It is the pipe itself, which was made using anti-corrosion materials. The pipe must cope with pressure and sudden temperature changes. In the manufacture of pipes, three types of materials are used - steel, cast iron and non-ferrous metal.
Important! Depending on the tasks, either a refrigerant or a heat carrier is allowed through the pipes.
Ribs. They are attached to the base. Since the entire surface of the petals is heated, the efficiency of the pipe remains equally high, regardless of the temperature of the coolant.

Interesting! Ratio of ribbing = area of ridges + area of areas between them / non-ribbed surface. The higher the ratio, the higher the efficiency.

During the production process, cast iron pipes are cast immediately with ribs. When working with other materials, the following tricks apply:

crimping washers;
high-frequency welding of elements;
electric arc and resistance welding;
cross-helical knurling;
winding with tension of a metal tape on the base.

Interesting! Ribs with slots can sometimes be found. The slots also ensure efficient operation of the pipe.

Pipes made by rolling aluminum can withstand temperatures up to 350 ⁰C, while pipes made by winding a steel strip onto a base can withstand higher rates.

Advantages of finned tubes

Pipes with a heat-resistant layer coated with magnesium oxide have the following advantages:

high heat transfer coefficient;
high resistance to corrosion and temperature drops;
long service life;
work in any conditions, even in aggressive ones.

Due to these important advantages, heat-resistant finned pipes have the following advantages.

Turbulent air vortexes pass between the ribs. This allows you to increase the intensity of heat transfer throughout the pipe.
Resistance welding in the manufacture of a pipe with ribs consumes little energy, which means that there is no need for expensive equipment and special materials. In addition, this welding allows the creation of zones with low thermal resistance.
The use of a heat-resistant coating reduces the level of condensation, which increases the service life.

System advantages

Cast iron batteries have a number of significant advantages that make them the most optimal option when designing a heating system.The list of the main advantages of finned tubes made of this heavy-duty material is as follows:

high thermal conductivity;
weak susceptibility to corrosion both outside and inside the product;
affordable price;
service life over 100 years;
the ability of the material to retain heat for a long period.

A little about the scope

Finned tubes are extremely popular today. They can be seen wherever a room needs to be either heated or cooled.

As we mentioned earlier, the efficiency of finned tubes is based on the high heat transfer achieved by the design features.

Finned tubes are part of many devices in private homes and factories. In the first case, they are used in air conditioners, since they help in air cooling as much as possible. In the second case, they are used not only for cooling, but also for heating the room, and also help in getting rid of aggressive gases and liquids.

The most popular area of production where finned tubes can be found is mechanical engineering. There they are used in the manufacturing process of various devices:

compressors;
refrigerators;
electric dryers;
oil coolers;
air heaters.

Distinctive feature

Even after the appearance of an alternative in the form of bimetallic or aluminum sections, cast iron radiators have not lost their fans. Most likely, this lies in their technical characteristics, which were able to prove to everyone that cast iron heating devices meet all the requirements.

We believe that they should be told in more detail:

Rust resistant	Cast iron is not susceptible to corrosion, which is an important property, especially when the system is drained in summer.
Durability	A very important product advantage. If you follow all the rules of operation, including regular preventive maintenance, cast-iron batteries for heating a house can stand without repair for almost half a century.
Coolant quality	Alas, in centralized heating systems, the water quality is poor. It contains various chemical compounds, rust particles, alkali and others, to which the internal surfaces of the radiator do not react. In addition, it is not so easy to scratch and dissolve cast iron.
Clogging	Wide channels ensure normal circulation of the coolant. Therefore, even if there are foreign objects or deposits in the system, this will not be a problem.
Storage capacity	Cast iron products are very thermally inert. They take it for a long time, but then they give it up for a long time if the system is turned off. For example, after an hour, the heat transfer will be 30%. If the heat supply is periodically cut off, the batteries will be able to smooth out its short-term absence.

Cheboksary cast-iron heating radiators in modern design

Advice: cast iron radiators can withstand temperatures up to 150 ° C, and therefore can be used in a steam heating system.

Additional benefits:

The radiator walls are thick, which also contributes to the durability of the device... This is especially ideal for open-type heating systems where oxygen levels are always high.
Low price opens access to products for people with low material income... It should be admitted that a cast iron radiator is much cheaper than other metal alloys. When equipping a home, these savings can be decisive.

Another option for a heating radiator is a ribbed cast iron pipe

Among the shortcomings, the following should be noted:

A large mass of the product, so it will not be possible to cope with it alone, you will need help.
Impressive dimensions when compared with modern bimetallic or aluminum counterparts.
For 1 kW of thermal energy, an average of 45 kg of battery weight comes out.The indicator is much inferior to the same bimetallic or aluminum registers.
The maximum pressure for which they are designed is up to 15 bar, although for bimetallic this parameter is up to 40 bar.
Low heat transfer, which is why the room warms up slowly.
The inter-sectional space is of a complex shape, so it is difficult to clean the radiator from dust.

How to choose

Before sending to the store for a cast iron radiator, you must consider some technical criteria:

the heat transfer parameter of the section, which will help to select a product in accordance with the dimensions of the heated room;
the total mass of the radiator, this is necessary to select the mounting location;
height, width and depth of the device;
the total power of the register.

Heating cast iron radiators (China)

To calculate the heat output of a cast-iron battery for each individual room, use the following rule:

for a room with 1 window and 1 outer wall, 1 kW of heat transfer per 10 m2 of area is enough;
1.2 kW / 10 m2 will be required for a room with two outer walls and one window;
1.3 kW / 10 m2 is required to heat a room with 2 windows and 2 outer walls.

Battery "Breeze" meets all quality standards

We also recommend paying attention to the following factors:

the power is calculated at a standard ceiling height of 2.5 m, in case of an increase in the parameter, it must be increased proportionally;
if the room is equipped with double-glazed windows, the design capacity can be reduced by 15%.

Tip: you can calculate the number of required sections by dividing the total required power for heating the room by the power of one section.

The instruction recommends installing radiators under each window in the room. So you will be able to significantly reduce heat loss.

Standard dimensions of cast iron radiators:

section width - 40-60 mm;
depth - 110 mm;
center distance - 500 mm.

Modern tendencies

It is becoming more and more difficult for manufacturers to sell old models, so today the market is trying to capture the buyer with the originality of the design. Most of us, when we mention cast iron radiators, immediately associate with something rude and unaesthetic.

Therefore, the designers and designers decided to breathe new fresh solutions into the product:

A beautiful ornament can now be displayed on the surface of the device, which matches the style of the room.
It was possible to reduce the dimensions, while increasing the heat transfer.
The ribs are now positioned vertically, which also increased heat dissipation, and cleaning now takes place without problems.
New dimensions were added, which made it possible to place heating devices of a new generation in a small window-sill niche.
Legs appeared on some models, which saved homeowners from drilling walls. Now the radiator can be installed on the floor and connected to the heating network with your own hands.
The color palette has also diversified, in which there are green and purple tones, copper and bronze, silver and gold.
Recently, reproductions of old models of radiators, which resemble samples of distant eras, are gaining popularity. They are decorated with artistic casting and equipped with appropriate fittings. These exquisite models of products help to ennoble the interior, becoming a part of it. The cost of such products, of course, is higher than the standard ones, but you can choose or order an individual model that will exactly suit your taste and preferences.

What to choose - domestic model or foreign

Companies from many countries are represented on our market, including Germany, Great Britain, China, Czech Republic, Turkey, Italy and Spain.Their difference from domestic products is higher quality and aesthetic surfaces. In addition, the thermal power of the device remains the same, but its dimensions are significantly reduced.

Model range of radiators with legs made of cast iron Retro (Turkey)

For example, a Czech radiator holds 800 ml of coolant in a section, while a Russian classic MC-140 has 1.3 liters. So with the same heat transfer, the foreign version will be more compact and lighter.

The inner surface of foreign radiators is almost perfectly smooth, and this helps to reduce the resistance to the movement of the coolant and prevents the formation of scale layers on the walls of the battery.

Also, imported options are offered already painted, while domestic ones need painting after installation. One of the disadvantages of imported products is the high cost of models, which significantly exceeds the cost of domestic samples.

Do-it-yourself pipe finning - how to achieve this

When making pipes with finning on your own, it is imperative to take into account the decrease in the efficiency of the "handicraft" pipe in comparison with factory samples.

Finning a pipe at home can be done in the following ways:

welding;
wire winding;
notch in conjunction with welding;
threading with a lathe (be sure to make a deep profile);
notch and tension.
