Replacing batteries using gas welding: an analysis of the general technology and small nuances

Welding battery replacement process

If it is planned to change old radiators for batteries of a different type or change the number of sections, this must be agreed with the management company. You also need to provide documents confirming that the work will be performed by a qualified welder. Self-employment is punishable by a large fine.

Preparatory work

First of all, nearby furniture is removed from the welding site, adjacent sections of the wall and floor are covered with non-combustible material. To shut off the heating and drain the water in an apartment building, a specialist from the housing office is called. In private houses and autonomous heating systems, a drain valve is provided for such cases. Then, using a grinder, the old batteries are dismantled. Pipes suitable for the radiator must be cut evenly so that there is no difficulty when installing a new one.

Assembling a new heating system

You can assemble and install a new heating battery yourself without calling a wizard. For this you need to stock up:

• a set of nuts (under the battery);
• two ball valves;
• Mayevsky's crane;
• packaging paste;
• linen seal or fum tape.

Before tightening, the nuts are treated with paste, and a sealant is wound around the threaded joints. Ball valves are installed on the supply and return pipes. They are necessary to disconnect the radiator from the heating system in emergency situations. On the other side of the battery, a Mayevsky crane is screwed in at the top. Air plugs, which are often formed in central heating systems, will descend through it.

Ball valves are installed without fail to turn off the radiator in emergency situations

Gas welding

The completed battery is put in place, hanging on special mounts. To prevent air from accumulating inside, the installation of heating radiators is carried out according to the building level. Dirt is removed from the ends of the elements to be joined and degreased. The supply and return pipes are connected to the radiator at a slope so that air pockets do not form.So that the circulation of the coolant is not disturbed when the valves are closed, a jumper from a pipe of a slightly smaller diameter is welded on the radiator between the supply and return.

Welding is carried out by heating the joint with a torch while feeding the filler wire. Melting, it fills the gap between the ends. Ideally, the filler wire material should be the same as that of the pipes or as similar as possible in composition. The best results are obtained when working with an acetylene torch. The use of methane and propane is permitted provided that their combustion temperature is twice the melting temperature of the filler wire. The heating rate and the type of seam are determined by the welder, depending on the wall thickness and the material to be welded.

Cleaning and painting

At the welding joints, scorch marks and black stains are formed. To remove them, processing is carried out followed by staining in the following order:

1. The surface of the pipes is cleaned with sandpaper No. 3 or 4. If there are sagging from welding on the seams, they cannot be removed with a grinder, as the strength of the connection will decrease.
2. From the cleaned places, first with a damp cloth, and then with a dry one, dust is removed.
3. Solvent degreasing is carried out.
4. Treated in two layers of anti-corrosion primer.
5. Heat-resistant enamel is applied in 2-3 layers so that the blackness does not shine through.

Pipes and radiators are painted when they are cold. Therefore, if the pipes are replaced in the winter, the heating will have to be turned off. The color is chosen in accordance with the design of the room or a contrasting option.

Accident during the heating season and outside it

The housing company is fully responsible for intra-house communications, if the tenants did not make repairs on their own. Therefore, if the pipe burst during the heating season, then all responsibility falls on their shoulders.

Outside the heating season, an accident can also occur, despite the fact that the coolant does not circulate at this time. Heat supply companies at the end of the heating season begin to conduct hydraulic tests.

This is necessary to identify problem areas and eliminate them before the start of the next heating season.

To exclude such actions:

• residents are temporarily disconnected from supply lines;
• service in each apartment installs valves.

Do not rush to immediately look for those responsible for what happened - we recommend fixing a breakthrough so that you can later use a photo or video when trying a case in court.

2 What are the requirements for installing gas water heaters in a private house

A prerequisite for any potential user of a water heater is to know what are the requirements for a gas colony in a private house.

First of all, you need to know the snip gas water heaters for a private house, which sets the requirements for the room in which the water heater is planned to be installed: the minimum area is 15 square meters, the ceiling height is at least 2 meters, the presence of a window is at least 0.5 m 2, the presence of ventilation (or installed hood for geyser in a private house), water pressure - from 0.1 atm., a wall under a gas column should be made of brick or concrete, otherwise insulation is required with a special cardboard made of basalt.

In addition, the standards for installing a geyser in a private house are required to comply with the following parameters:

1. There should be a margin of 60 cm in front of the front panel of the gas column;
2. The distance from the water heater to the gas stove is at least 20 cm;
3. The stopcock is mounted before the column is installed.

The rules for installing a geyser in a private house also regulate the procedure for legalizing the installation of a geyser. To obtain permission to install a water heater, you must obtain a project for your house and check the condition of the chimney (after which you receive an act), then the owner of a private house draws up an application for the conversion of his home.

You will also need those column passport, or its model (if the latter has not yet been purchased). After that, you can contact GORGAZ to carry out the tie-in.

You should know the subtleties at each stage of installing a geyser in a private house. This will be needed both for partial installation with your own hands, and for calculating all the nuances of the work. Experienced professionals share the following tips:

• If you decide to disguise the geyser in a snag cabinet, this is possible. But you should be aware that such a cabinet should not have a bottom, and the side walls should have high-quality insulation;
• If you hesitate in choosing between installing a chimney pipe, opt for corrugations made of laminated aluminum. Such a pipe is perfect for a private house, as it is easy to install, quite reliable and inexpensive, and inside it has steel pipes that prevent sagging;
• If you plan to mount a geyser instead of an old one that has become unusable, then it is best not to change the installation site. So you save time and some money;
• Remember that in case of unauthorized insertion into the gas pipeline and connection of the gas column, you will face administrative responsibility, in the form of a fine.

Paying attention to customer reviews, there is often a problem when the geyser freezes in a private house

Masters advise first of all to pay attention to the draft in the chimney

Most often, a malfunction in the form of reverse thrust is the cause of the failure of the water heater. The collection of gas column condensate in a private house may appear if an ash pan is not installed in the system, and condensate is already drained from it. Otherwise, this problem will occur every winter season.

The presence of such an installation in a residential area is a reliable, popular, economical option for obtaining hot water of the required volume with a centralized gas supply or from a cylinder.

In addition to specific information on the site, you can also study specific problems for other people on this topic who have already bought a gas water heater or instantaneous water heater and thus avoid them. You will find a regularly updated list of such problems and their solutions.

This is the least expensive and time consuming option. When replacing, there is no need to obtain a project. Before starting work on replacing an old water heater, it is necessary to obtain certified copies of the schemes, a plan for installing gas, water, and smoke systems from the Housing Office. The gas supply plan must indicate the location, technical parameters of the device.

After receiving the documents, you must write an application to Gorgaz with a request for permission to replace the old equipment with a new one, while maintaining its previous location, an application for permission to work on gas and water communications in your home.

How to get work permits?

Only professional gas welders who have a certificate of education in this specialty are allowed to install heating batteries using gas welding. In addition, the welder must have a valid fire safety permit. It is desirable that the specialist has experience (excellent, if many years) in gas welding. It affects the quality of the final result and the equipment used, which must be not only serviceable, but also meet the established safety requirements.

Gas welding work is carried out in overalls, in special glasses with a protective shield that prevents the eyes from catching "bunnies", as experienced welders say. We must not forget about gloves that protect the skin of the hands from the effects of negative factors.

The mandatory equipment of a gas welder includes such protective equipment as goggles, a shield, and work gloves. All listed items are intended for gas welding work.

Please note that at the moment in apartment buildings there is a ban on gas welding without obtaining permission from the authorized bodies. Violators of this legislation face a hefty fine.

How to legally change the heating in the apartment

Replacement of radiators in the apartment must be carried out with the consent of the management company.To do this, it is necessary to write an application to the chief engineer of the Criminal Code, where to petition for consideration of the possibility of replacing the radiator for certain reasons.

With the consent of the management company, you will have to order a project for the reconstruction of the heating system in the organization that has the approval of the SRO. Further, the chief engineer of the management company agrees on the project or sends it to the interdepartmental commission. After the MVK, the chief engineer again takes over. Next, to replace the pipe, hire an organization with an SRO approval (even if your relative is a certified welder, he can replace the radiator in the apartment only if he has a welder’s certificate and a fire safety permit). Copies of all documents are kept by the management company.

Welder's certificate

In case of refusal, you can go to court or insist on the management company fulfilling its obligations, including replacing the heating system in an apartment building.

It is interesting: Which pipes to choose for heating: which better options and why?

What is needed for electrical welding?

To weld pipes using electric welding, you will need a welding machine. Today, there are two types of such devices: devices made on the basis of a step-down transformer, and inverters that operate at high frequencies. The first type is used extremely rarely, since it is considered obsolete. The inverter is a more modern device that is simple and portable. It is possible to adjust the welding mode with high accuracy. True, inverters are considered less reliable in use. Therefore, to work with such equipment, it is necessary to have a certain qualification.

In addition, heating welding involves the presence of other auxiliary equipment:

• special mask with a light filter. It reliably protects the eyes and face from sparks and particles of molten metal during welding;
• overalls for body protection;
• suede gloves. With their help, the device in the hand will hold securely;
• electrodes;
• metal brush. Necessary for cleaning the pipe section before welding, to remove scale;
• a special hammer that is used to knock down scale.

What should be considered in advance?

If the decision to carry out repairs of this type is made, a number of questions should be answered:

1. When and by whom will the work be carried out?
2. What type of radiators should be used?
3. Is it necessary to replace the pipes leading from the battery to the riser?
4. How many sections will be needed for each room?

It is best to carry out such an alteration in the summer, because to start work, you must obtain permission from the local housing office. In winter, officials are extremely reluctant to give such permissions, because they will have to block the common riser and leave other apartments without heating for some time.

But even outside the heating season, getting permission can be difficult. Those who have already solved similar problems talk about the need to wait for several days, trying to get an appointment with the right employees, etc. Some faced pressure: they were recommended to hire plumbers from the Housing Office to do all the work.

There are no restrictions on this issue. The main thing is that the replacement of heating batteries is performed by an experienced plumber with the appropriate qualifications. It is possible to identify all the flaws made during inept installation only during operation.

Old radiators get dirty inside and out over time, cleaning does not always solve the problem of insufficient heating, replacement is a more effective option

It is best to go to the housing office in the summer, and not in the fall, which is the peak of the queues. By this time, all the necessary materials need to be purchased, pre-assembly of radiators, tools prepared, agreed with the team, if necessary.

If the house is connected to a central heating system, you should contact the maintenance service to agree on the alteration. Here they can perform the necessary calculations to accurately name the number of radiator sections, as well as clarify other technical issues.

Shut-off valves that are installed on the “supply” and “return” are necessary so that at any time you can turn off the water and remove the battery for repair or replacement

The lack of correct calculations can lead to an imbalance in the home heating system.

Previously, for the calculations, you will need information that is in the DEZ:

Most often, old batteries are replaced with new modern models, usually aluminum or bimetallic. Although cast iron, copper and steel products are also on sale. The type of radiator is needed when performing calculations.

When choosing a suitable radiator for a house or apartment, you need to focus on its main characteristics, which are detailed in the product data sheet.

You will need such indicators as the pressure that the device can withstand, the maximum temperature of the coolant, heat transfer and other data. They can usually be found in the technical data sheet.

If not only radiators, but also pipes leading to them are to be replaced, a suitable material should be selected. Usually it is steel, metal-plastic or polypropylene. Some masters strongly recommend using only steel communications for centralized systems.

Depending on the type of pipes chosen, you will need the appropriate equipment for welding them. MP and PP pipes are easier to install than steel. To work with metal, you need not only a welding machine, but also a device for threading. Therefore, if the old pipes are clean enough, it is recommended to leave them and replace only the battery.

Old cast-iron radiators retain heat well, but slowly release it, in addition, they are heavy, which complicates installation, so bimetallic and aluminum models are more popular

The weak point of metal-plastic structures is connections. They must be performed very carefully, installation errors often lead to leaks. The popularity of MP pipes is explained by their relatively low price. Plastic is more expensive, but more reliable, if the welding is done correctly, the tightness of the joints will be very high.

Under the selected radiator, you need to select suitable fasteners. In this case, it is necessary to take into account both the type of radiator and the material of the wall on which the installation will be performed: brick, concrete, etc. Batteries are usually supplied with brackets of the appropriate type.

To install one radiator, two brackets are usually used at the top and one at the bottom. Their position is carefully checked by a level in order to eliminate the possibility of distortion during battery installation. However, some models are set with a slight slope to ensure the removal of air that has entered the system.If there are more than twelve sections, another top bracket may be needed.

Replacing heating batteries with gas welding

Sooner or later, all owners of real estate objects have to think about what it is to replace heating batteries, what expenses it entails and is necessary, and this in general. And at the same time, how to choose radiators, you have to immediately think about how they will have to be changed later. There are several ways to replace a heating radiator. However, experts note that gas welding remains the most reliable and efficient of them. Let's consider this method in more detail.

• What is the feature of gas welding?
• Changing batteries
• Welder and equipment: what to consider?
• Gas welding vs. Threaded method: who wins?

Replacing heating batteries for welding: what you need to know

In order to save some money, some users try to replace the batteries in their home themselves. However, it should be borne in mind that replacing batteries requires 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, welding of radiators should be carried out only with the use of modern equipment and only by a qualified specialist. The welding process is as follows

First of all, it is important to find out what operating pressure is in the heating system, if it exceeds 8 atmospheres, then you should buy bimetallic batteries

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

Our specialists use only high-quality and reliable equipment that allows you to quickly dismantle and install the battery. Our welding equipment is stable and high quality, so that there are no complications in the battery welding process. The masters of our company have vast experience in welding, which allows them to perform work of any complexity with the highest quality and accuracy.

Replacing batteries with gas welding 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 carry out the replacement, it is important to correctly determine how the installation of heating radiators will be performed. There are many options by which the work 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 degree of reliability. Provided that the work is done by a highly qualified craftsman, the resulting seam will be reliable, thanks to which it can ideally serve for many years. The welded seam, in addition, will not require additional attention, as is observed when performing installation using mounted joints. This is due to the fact that the junction does not have an additional seal, which, as a rule, is short-lived in operation.
• Neat appearance.After the welding work is completely finished, the seam remains almost invisible, so that it does not spoil the external design of the room and can remain in the open.

Only an experienced craftsman 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 masters of our company are able to perform the installation of radiators using gas welding with high quality and accuracy.

The 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 a temperature that is required by the technology and the 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 battery replacement work consists of:

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

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

How to replace gas welding heating batteries

As already noted, with the help of gas welding, it is possible to install heating radiators with the highest quality and reliability. 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 quickly possible to connect steel pipes to a radiator, the outer diameter of which does not exceed 100 millimeters. The attachment points (weld seam) are reliable and able to withstand high operating pressure in the system, which eliminates the possibility of a breakthrough. It should also be noted that the seam made by the master looks very neat compared to the fittings and other available

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 ways to installation difficult to make the right choicewithout 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 replacement and installation work is not carried out properly.

Basic Battery Replacement Steps

To dismantle radiators in an apartment on an open heating system, you should obtain permission from the local housing office and heating networks. Separately, it is necessary to agree on the modernization of the design, for example, if you are planning move the batteries to another location, add or remove several sections.

Welding work, as already mentioned, is allowed to be carried out only by specialists with permission and vocational education - independent initiatives can result in a decent fine. Therefore, we will consider the main stages of the upcoming repair in order to avoid unpleasant surprises.

Performing preparatory work

To begin with, it is worth minimizing the possible consequences of the operation of a gas welding machine. Furniture close to the radiators must be taken out or closed from possible damage. Also protect the area of ​​the floor and wall adjacent to the battery.

Then water is drained from the heating system. If we are talking about a private house or other room with autonomous heating, a special tap is used, which must be provided for in the design.

In an apartment with central heating, it is impossible to independently turn off and drain the coolant from the system - you should call a specialist from the service organization. Next, you need to disconnect the radiators that have served their time. The easiest way to do this is with a grinder.

But even here you will need a good skill with the tool, because in order to connect new heaters with a minimum of effort, it is important to make a neat and even cut.

Assembling a new design

Next, the new radiator is packed. If you want to save on the services of masters, this work is quite feasible to do yourself.

Required materials and tools:

• A set of nuts (for radiators).
• American ball valve.
• Mayevsky crane.
• Wrench.
• Packing paste.
• Sealant (flax or fum-tape).

To assemble the battery, you need to seal the nuts, process with paste and screw onto the pipes at the junctions. The layout of the radiator is completed by installing cranes.

On the side of the connection with the heating system, an "American" is mounted in order to be able to block the access of the coolant to a specific battery. From above, on the opposite side of the pipe inlet, a Mayevsky crane is screwed with a wrench, with which it will be possible to remove the “plugs”, dumping air accumulations from the system.

Gas connection

The assembled radiator is suspended in place of the old battery using special fasteners, and the evenness is checked without fail with a building level. Before starting welding, the ends of the elements to be joined should be thoroughly cleaned of dirt, dust and degreased.

Next, the inlet and outlet pipes are welded with a verified slope, which helps prevent the formation of air pockets. To do this, the connecting segment is heated with a burner, while using a filler wire that fills the gaps between the fragments of the system.

The type of seam and the heating rate are chosen by the master, based on the wall thickness, pipe material and other professional nuances.

Seam cleaning and finishing

After the work of the gas welder, the pipes look unaesthetic: black marks and stains are unlikely to become an interior decoration. But this is fixable.

To process the welding site, you need to act according to the following algorithm:

1. Clean the pipe with sandpaper with grain size 3 or 4.With the inaccurate work of the welder, there may be a thick influx at the junction, which some try to even out with the help of the same grinder. But you should not do this - you can violate the strength qualities of the seam.
2. Dust the pipe - wipe it with a damp and then dry cloth.
3. Degrease with white spirit.
4. Coat with anti-corrosion primer in 2 layers.
5. Paint with heat-resistant enamel also in 2-3 steps (the lighter and more transparent the paint, the more layers may be needed to mask the black).

Of course, all painting work should be carried out before connecting the system, on cold pipes. If the batteries were replaced during the heating season, it is necessary to block the access of the coolant and wait for the system to cool completely.

You can decorate only pipes or the entire structure complete with a radiator. The color is usually chosen white, silver, bronze or to match the tone of the walls. But for some interior styles, you can also apply a contrasting shade, for example, dark chocolate, glossy black or spectacular red.

It is possible to open the system and fill the circuit with coolant only after the paint has completely dried.

Should batteries always be classified as common property?

In the decision of the Supreme Court of the Russian Federation dated September 22, 2009 No. GKPI09-725, it is determined whether the heating radiator in the apartment belongs to common property. Based on the provisions of the Housing Code of the Russian Federation, the highest judicial authority found that the heating elements of the in-house heating system, serving only one apartment, are not part of the common property of the owners of premises in the MKD.

We suggest that you familiarize yourself with the Law on obtaining an apartment for orphans

So, only batteries that serve more than one dwelling, including those without shutoff valves, which are located on branches from the risers of the in-house heating system and are located inside the apartments, are considered common property.
