When building a new house or overhaul apartments have to deal with the installation of new heating elements. Moreover, the problem here is not only in the choice of radiators and pipes through which the coolant will move, but also in the method of combining disparate parts of the structure into one reliably working system.

There are several options for connecting pipes: replacing heating batteries with gas welding, electric welding or a threaded method. Although each technology has pros and cons, most craftsmen tend to prefer gas welding. Why? Let's consider in detail and with examples.

The fastening of heating pipes by gas welding is carried out according to the following principle: the end parts of the two elements are combined, and then gradually warmed up in the tribe of the gas-oxygen mixture to high temperatures.

It is best to replace radiators in the warm season, since during the cold season you will have to turn off the common house heating for at least a few hours, which is unlikely to please the neighbors

For extra strength of the seam, a filler material in the form of a wire or a rod is used. When the hot metal cools down, a monolithic joint is formed.

Advantages and disadvantages of welding pipes

One of the main reasons for the popularity of the gas welding method is the specificity of the operation of our heating systems. During circulation, all structural elements are constantly under pressure, which deforms the joints.

Therefore, a durable weld seam reliably protects against breakouts and helps to prevent accidents during short pressure surges and even that often accompany the start-up and shutdown of centralized heating.

1. I install radiators regardless of the location of the old supply pipes.

2. In addition to the quality of installation, I also pay great attention to the aesthetics of the general form of connection.

3. I don't use old pipe pieces, bends and welded threads ... just a solid pipe that I bend and thread.

4. I use a "roller" pipe bender, which guarantees a small radius and perfectly straight pipe bend, regardless of the quality of the pipe being bent.

5. I use an anaerobic sealant to package the taps and install the American women (guarantee for the entire life of the connection without corrosion).

6. In those cases where the installation of taps is done on linen with paste, I make knurling of notches, which guarantees the fixation of the flax and prevents it from being squeezed out.

Replacement of gas-welded heating radiators

Installation, installation of one heating radiator with a turnkey pipe bender - from 10.000 rubles

This bag includes ... dismantling the old radiator and all the necessary preparatory and installation work: measurements, threading, packing taps, bending pipes.

As a rule, there is a partial replacement of the riser from the floor to the middle of the riser, above the mounting sleeve, including a complete replacement of the horizontal supply pipes. This makes it possible to achieve horizontal and parallel accuracy of the positioning of the supply pipes in relation to the radiator and the wall. As a result, it allows you to place the radiator as expected, regardless of the location (height) of the lower and upper horizontal supply pipes.

Since I use a pipe bender, therefore, only the pipe itself is purchased, which I myself bend and cut threads only in the right places for installing taps at the place of work ... and all this (except for the pipe itself) is already included in the price of installing the radiator !! !

Steel tubular and other non-standard designer radiators Zender, Arbonia, bay window, niches and other non-standard types of connection - from 12,000 rubles

Remove the convector (old radiator) and straighten the heating riser - 6.000 rubles

Estimated time for gas welding work - from about 3 days (it all depends on the complexity and the number of radiators)

First and second day: arrival and preparatory work on the assembly of new radiators, fixing brackets and hanging radiators (if possible), measurements, bending and cutting pipes, cutting threads and packing valves - the most complete preparation before the final stage of pipe welding.

The third day: shutdown and drainage of water for the final final stage of work - overwelding of the supply pipes.

As a rule, the last stage of welding (taking into account the fit) takes about 1.5 - 2 hours for each radiator.

Overcooking of gas-welded water supply risers

Overcooking of one riser of water supply in a straight line (galvanized) - from 15,000 rubles .

Estimated lead time for gas welding - about 3 days (depending on the difficulty)

First and second day: arrival and preparatory work ... procurement of stubs of risers with welding of new bends, bending of pipes for displacement of risers (if necessary) and packing of taps.

The third day: in the morning, shutting down and draining the water for the final, final stage of work ... overcooking of risers.

As a rule, so that there is no admixture, both water risers (cold and hot) are turned off simultaneously ... 2 hours

Working with freezing pipes

Replacement, installation of one heating radiator with freezing pipes, without disconnecting heating risers

Time of work with freezing pipes- from about 3 days (it all depends on the complexity and number of radiators)

It all depends on the complexity of the execution ... how many replaceable radiators, so many days of work, taking into account the stages and preparatory work + the installation itself.

As a rule, the work takes place in several stages:

1. The most difficult ... is freezing the riser and dismantling the old convector with a temporary bridge to restore circulation through the heating riser.

2. Assembling a new radiator and hanging it in the right place, followed by taking measurements and preparing the necessary blanks for supply pipes.

3. Final stage ... re-freezing of the riser, with fitting and final connection of a new radiator.

When replacing radiators, many owners use an effective and reliable method of connecting pipes using gas welding. After welding, strong seams are formed that are able to withstand any pressure of water and any temperature.

Gas welding and threaded method: which is better

Installation of heating radiators is carried out exclusively by specialists. To use gas welding, an employee must have a special education and a permit to work with a gas welding machine.

It is desirable that he has experience in this area, because not only durability, but also operational safety depends on the correct connection of pipes.

The use of a threaded connection method does not require special skills and equipment. The process itself consists in twisting parts of the heating system together according to the principle of a constructor. A threaded connection takes much less time and cost for installation, but at the same time, the reliability of work is lower than when welding.

Even at high water pressure, the gas-welded seam will withstand the pressure without any problems, unlike a threaded connection. In the second case, a violation of the integrity of the radiator and a breakthrough due to strong flow water.

From the point of view of appearance, gas welding also benefits - for threaded connections, various connecting elements, nuts, fittings, and seals are used. Welding seams can be cleaned and painted over the pipe, making the seam virtually invisible.

Ultimately, the cost of gas welding can be lower than threading batteries.

Replacing heating batteries with gas welding: operation algorithm

If it becomes necessary to carry out gas welding in the apartment, you must obtain permission to perform them. Before starting the welding of radiators, you need to prepare the room - remove all flammable objects from the welding site, close the floor and furniture from sparks.

Gas welding is used for any type of metal of any shape and size.

In addition to gas welding machine, to replace the radiators, you will also need a grinder with a metal circle, a tape measure, a set of nuts, an adjustable wrench, investment paste and flax.

Replacing radiators step by step:

1. Draining water from the heating system. If the coolant is not removed from the old batteries, during dismantling, water will flow directly into the room and a flood may occur.
2. Dismantling of old radiators. Pipes are cut with a grinder with a metal nozzle, while you need to adhere to safety rules - use protective goggles and gloves.
3. Packing a new battery. At the joints, the nuts must be sealed with flax, lubricated with investment paste and screwed tightly onto the pipes protruding from the battery. In the place where the pipes are attached to the heating system, an American faucet and Mayevsky's faucet are screwed on.
4. Installing batteries. The new battery is put in place of the old one, after which all connections to the heating pipes are fitted by welding. After completing all welding work, the seams are cleaned.

When the work is completed, you need to check the heating system for strength. All joints must be sealed and well sealed so that the seams are not damaged when the coolant is supplied.

Installation of gas-welded heating radiators: what is needed for this

Sooner or later, the owners of both apartments and cottages are faced with the need to replace old pipes and radiators of the heating system. The process of installing new batteries is quite serious and must be taken seriously.

To carry out work on replacing the batteries, you need to write an application to the housing maintenance office with a description of the problem and the whole essence of the request. After considering the application, the housing office must consider the application and give an answer to the owner of the apartment. In case of agreement, the date of the work is discussed.

In no case should you replace batteries without warning, such amateur activities are fraught with fines, since a ban has been imposed on gas welding.

On this day, central heating is turned off throughout the house - this work can only be carried out by an authorized plumber or another employee of the housing office.

You can dismantle old batteries yourself, but it is recommended to entrust the installation of new radiators to a certified specialist. If you contact a specialized company that replaces batteries, all documents, from the permit and ending with the technical passport, can be dealt with by the company's employees. True, you have to pay for everything.

How to work with gas welding: instructions for use

Gas welding is widely used for automotive and construction works... When welding, the metal heats up, due to which the edges of the elements to be joined are melted. A special wire is deposited on this joint.

When welding, one of the flammable gases is used - acetylene, propane, methane, etc.

When working with a gas welding machine, it is very important to observe safety precautions. There should be no objects around the workplace that could catch fire. There should be a fire extinguisher or a bucket of water nearby. The technician must wear a protective suit with a mask and goggles to protect against sparks. In addition to the burner, it must have a set of 4 nozzles of different sizes.

The accuracy and accuracy of welding seams depends on practice - frequent use of a gas welding machine will help you gain not only experience, but also professional skill that allows you to work with the most complex orders.

How to work with gas welding (video)

Using gas welding to replace batteries in apartment building is the most acceptable and reliable method. The seams at the joints allow to withstand strong pressure, and exclude the violation of the integrity and tightness of the heating system.

Welding heating batteries: what are the advantages

Due to all the advantages of welding, many consumers prefer this option when replacing batteries. Welding heating batteries has the following advantages:

• Careful appearance, after painting weld remains practically unnoticeable.
• A high degree of reliability, provided that the welding work is performed by a specialist, the seam is characterized by high strength and durability. It is important to note that the weld can provide the system with much greater reliability than any other modern connection, such as a fitting.

The specialists working in our company are able, thanks to the availability of modern welding equipment, to install the batteries as soon as possible.

Replacing heating batteries for welding: what you need to know

In order to save some money, some users are trying to replace the batteries in their home on their own. However, it should be borne in mind that replacing batteries requires from the master not only knowledge and skills, but also compliance with certain rules. Violation of the battery installation process can lead to an accident and additional financial costs... Therefore, the welding of radiators should be carried out only with the use of modern equipment and carried out only by a qualified specialist. The welding process is as follows. First of all, it is important to find out what is the operating pressure in the heating system, if it exceeds 8 atmospheres, then bimetallic batteries should be bought.

Water is completely drained from the heating system, after which the old batteries are cut out with a grinder. The ends of the pipes are thoroughly cleaned of dirt and rust, after which a new battery is installed in the vacant space and, using a welding machine, is welded to the pipes of the heating system.

Our experts use only high-quality and reliable equipment that allows you to quickly dismantle and install the battery. Our welding equipment it is characterized by stability and quality, due to which there are no complications during the welding process of batteries. The masters of our company have vast experience in welding, which allows them to perform work of any complexity as efficiently and accurately as possible.

Replacement of gas-welded batteries is a guarantee of high-quality seams!

The appearance of new proposals on the heating equipment market prompts the population to think about replacing old batteries with new heating radiators. In order to perform a replacement, it is important to correctly determine how the installation of heating radiators will be performed. There are many options with which the job can be done, but the most effective is to use gas welding. This is due to the fact that replacing batteries with gas welding has many advantages, such as:

• Increased reliability. Provided that the work is done, there will be a highly qualified craftsman, the resulting seam will be distinguished by reliability, thanks to which it will be able to ideally serve for many years. In addition, the weld seam will not require additional attention to itself, as is observed when performing installation using assembled joints. This is due to the fact that the junction does not have an additional seal, which, as a rule, is fragile in operation.
• Neat appearance. After the welding work is completely finished, the seam remains practically invisible, so that it does not spoil external design premises and can remain in an open place.

Only an experienced master should be trusted to install heating radiators, since the efficiency and economy of the heating system will depend on the quality of the work performed. The craftsmen of our company are able to perform the installation of radiators using gas welding efficiently and accurately.

Advantage of replacing batteries with gas welding

Welding is a special process in which molten metal is poured between the edges of parts heated to a certain temperature. It is important to note that the edges are heated to the temperature required by the technology and characteristics of the material itself.

Gas welding works are carried out for welding metal parts of various shapes, in addition, welding is used to eliminate defects from a metal surface, regardless of its shape and size.

Gas welding work on replacing batteries consists of:

• preparatory part;
• welding (seam application);
• elimination of cracks and cavities from the surface of a metal part;
• smoothing seams (if necessary).

Only specially trained specialists are allowed to perform gas welding works, since only they are able to weld metal surfaces to each other as correctly and efficiently as possible.

How is the replacement of heating batteries by gas welding

As already noted, using gas welding, you can install heating radiators as efficiently and reliably as possible. The main explanation for this is that the metal edges of the pipe and radiator are connected by molten metal, which is formed as a result of the melting of the filler wire. With the help of gas welding, it is easy and most importantly quick to connect steel pipes with a radiator, the outer diameter of which does not exceed 100 millimeters. The attachment points (weld seam) are distinguished by their reliability and the ability to withstand high working pressure in the system, which excludes the possibility of a breakthrough. It should also be noted that the seam made by a craftsman looks very neat compared to fittings and other available
