Today, a wide variety of materials are freely available, and on the Internet you can find any instructions and, of course, try to replace heating devices yourself. But can you then be sure of the reliability of the result of your work? After all, it is not enough to choose high-quality materials, it is important to thoroughly observe the process technology. Otherwise, after all, you can be left without precious heat at the most inopportune moment - for example, in the midst of winter frosts. So, it is obvious that the installation of radiators using gas welding is a process that requires an exceptionally qualified approach. And, having become acquainted with the technology closer, you can easily verify this.

Replacing heating batteries with gas welding: the essence of the process

It is equally important to choose the right special equipment for welding. You will need to purchase a generator (acetylene or some other gas), as well as an oxygen tank and gas reducers. And, of course, the welding device itself. It can be a torch or a cutter with a set of interchangeable tips. Also, the mandatory list of equipment includes: a rubber sleeve, which is necessary for transferring gas to a tool from cylinders, a fire safety valve.

Replacing heating batteries with gas welding requires that you achieve strong connections, which means that it is necessary to approach the installation of equipment and the choice of welding method as responsibly as possible. You can choose from several existing types of connections, the most popular of which is butt. But if the material used has a thickness of more than 5 mm, then you will already have to choose a Y- or X-shaped cutting of the edges. The most profitable and economical ways of cutting pipes are oxygen, manual and mechanized.

A question that sooner or later arises in front of almost every tenant, whether it is an apartment in an apartment building or your own house in the private sector.

Among the variety of existing types of heating batteries and how to install them, it is difficult to make the right choice without having special knowledge and experience in this area.

Therefore, whether the heating batteries will be replaced by gas welding or a threaded method, and what type of radiators to use, it is better to decide together with qualified specialists. There is a high risk of costly property damage if the replacement and installation work is not done well.

Advantages and nuances

Today, the replacement of radiators of heating systems with gas welding is gaining more and more demand. This is easily explained: the resulting weld at the junction of the radiator with the pipe (riser) is much stronger than the welded parts themselves.

Such a connection is able to withstand both strong water hammer and high pressure, under which water is supplied to the heating system in all apartment buildings. Using the gas welding method, problems of leakage and breakdown of connections, as well as wear of its seal can be prevented.

When not to use

The appearance of a neatly cleaned weld is more aesthetically pleasing compared to bulky threaded connection fittings. However, it should be noted that gas welding is more suitable for dwellings with a central heating system. In private homes, batteries need to be cleaned and vented from the system much more often, so a threaded connection in this case is more optimal than a welding one: it will facilitate the installation process if necessary.

Replacement principle

Gas welding is the process of joining several parts by heating their mating edges and filler material to a melting point. The result is a high-strength joint that can withstand significant loads. Gas welding is carried out using special equipment: as a rule, it is an acetylene generator, an oxygen cylinder, gas reducers and a burner.

Execution of work

When performing gas welding work, first you need to obtain the appropriate permit for their implementation, if we are talking about an apartment building. It is also important to make sure of the qualifications of the welder who will carry out welding work: he must have the appropriate certificate and a valid fire safety permit.

Main stages

Very wide: bimetallic, most popular, aluminum, panel, cast iron. Each type has its own advantages and disadvantages, and the choice depends on the installation site and operating conditions.

Preparation and assembly

Before starting welding work, it is necessary to prepare the room: isolate the furniture, close the walls and floor from possible damage. It is necessary to drain water from the system, remove the coolant (in other variations). Next, with the help of a grinder, it is necessary to dismantle the spent radiators

After all the preparatory work, you need to assemble a new battery for installation. To do this, the nuts at the joints are sealed with flax, smeared with investment paste and tightly wrapped. A special air bleed valve is installed on top, and an American ball valve with a drive is placed on the side of the pipe connection.

Installation

The installation of a new battery is carried out on special brackets, after which all connections with pipes are adjusted - they are welded, and then the seams are cleaned. It should be borne in mind that gas welding usually produces a connection of pipes not exceeding 100 mm in diameter.

After welding, be sure to check the system for strength and tightness. Replacing radiators with gas welding compared to the threaded method is a longer and more expensive process, which has some disadvantages. But quality, reliability and durability are an indisputable and winning advantage.

More about the differences

Replacing batteries by gas welding differs from the threaded method in several ways. So, in addition to the already mentioned aesthetics and the absence of massive nuts and fittings, gas welding allows you to create very strong connections.

So, in the threaded method, more than 12 seams are created, and in the gas welding method, as a rule, no more than 5. This protects the batteries from breaking through the heating system during pressure surges. The absence of seals also contributes to the durability of the structure.

The welding connection is indispensable, since this is the only way to replace batteries in high-pressure systems: in such cases, the thread simply cannot withstand the load and the pipes break through.

Over time, the owners of their own home ownership or apartments in a multi-storey building have to deal with the replacement of heating batteries. It is advisable to determine how to install radiators - using gas welding or a threaded method - together with highly qualified specialists.

Benefits of replacing appliances with gas welding

Without the possession of special knowledge and skills in carrying out work in this area, it is difficult to decide on the option of installing radiators. It is important to remember that poor-quality installation of heating equipment can result in costly damage to personal and sometimes other people's property.

In recent years, heating batteries have been increasingly replaced by gas welding. The reason for the great demand is that the resulting weld at the junction of devices with a riser (pipes) significantly exceeds the strength of the elements joined together.

This type of connection is able to withstand water hammer and increased pressure of the coolant supplied to the heating system in multi-apartment buildings. The use of gas welding when replacing radiators makes it possible to avoid leakage and rupture of the joints, as well as wear of the seals used.

Features of the use of gas welding

Outwardly, a neatly cleaned weld looks more aesthetically pleasing than bulky threaded fittings. But at the same time, it must be borne in mind that the installation of heating radiators for gas welding is more suitable for residential facilities with a centralized heat supply system.

In turn, in private households, it is necessary to more often perform work related to the removal of air from the heating structure and cleaning the batteries. For this reason, in this situation, the use of a threaded connection is preferable compared to a welding one, since it makes the process of dismantling / mounting devices easier.

The nuances of gas welding work

The connection of several parts during gas welding occurs by heating the joined edges and filler material to the melting point. As a result, the formed connection is characterized by high strength and the ability to withstand significant loads.

Batteries are replaced by gas welding using special equipment - an acetylene generator, an oxygen cylinder, a burner and a gas reducer. To carry out gas welding work in an apartment building, you need to obtain an appropriate permit. The welder who must perform this type of work must have the appropriate certificate and fire safety permit.

Stages of work on replacing heating batteries

Each model range of radiators has advantages and disadvantages, depending on the place of installation and operating conditions.

Change the batteries in stages:

1. Preparatory activities. Before replacing batteries in gas welding, you need to prepare the room, namely, isolate pieces of furniture, cover the floor and walls, protecting them from damage. Fluid is drained from the system. Using the grinder, the devices that have become unusable are dismantled.
2. Assembling a new radiator. At the joints, the nuts are sealed with flax, smeared with investment paste and carefully tightened. A crane is placed on top, designed to release air, and from the side of the dock with the pipe, a crane is installed - an American with a drive.
3. Installing a new radiator. It is placed on special brackets, after which all connections with pipes are adjusted - they are welded, and then they are cleaned. You need to know that gas welding is carried out with pipes whose diameter does not exceed 100 millimeters.
4. Final stage. After the replacement of heating radiators for gas welding is completed, the heat supply system should be checked for the strength of the connections and their tightness.

The use of gas welding compared to the threaded method is a more expensive and time-consuming process, which has disadvantages. But the advantage of this installation method is its durability and reliability.

The difference between the two replacement options

Replacing batteries with gas welding has several advantages over the threaded method:

• welding creates very strong connections;
• the seam is more aesthetic than the presence of massive fittings and nuts;
• the absence of seals contributes to the durability of the joints;
• this is the only way to mount radiators in systems with increased pressure, since the thread will not withstand such loads;
• when using the threaded method, more than 12 seams are formed, and when gas welding - no more than 5.
