We are confident that if you have not yet changed your heating radiators, then you have yet to do so, which means you will need to solve a lot of questions at once: whether to do it yourself or invite a specialist; what materials to use; what technology to use. Replacing heating batteries with gas welding is the best alternative to the old ones cast iron radiators, which have already reached the end of their service life. But, unfortunately, it is often not only them that have to be changed. Many happy owners of apartments in new buildings are dissatisfied with the aesthetic appearance, heat transfer and safety of already installed heating devices.Replacing heating batteries with gas welding (from 4 pcs) 4000 rub

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 select high-quality materials; it is important to thoroughly follow the process technology. Otherwise, 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 installing radiators using gas welding is a process that requires an exclusively qualified approach. And, having become more familiar with the technology, you can easily verify this.
Replacing heating batteries with gas welding: the essence of the process
Gas welding at its core is heating the edges of parts of a structure. In some cases, filler material is used in the process. The main advantage of the technology is the absence of the need for a source electrical energy, as well as high reliability and tightness of the resulting seams. But in order to achieve this effect, you need to know some features. For example, the power of the heat source must be sufficient to carry out a continuous process, and the temperature must be higher than the oxidation temperature of the metal in the gas.It is equally important to choose the right special equipment for welding work. You will need to purchase a generator (acetylene or some other gas), as well as an oxygen cylinder and gas reducers. And, of course, the welding device itself. It can be a torch or a cutter with a set of replaceable tips. The mandatory list of equipment also includes: a rubber hose, which is necessary to transfer gas to the tool from cylinders, and a fire-preventing valve.
Replacing heating batteries with gas welding requires that you achieve strong connections, which means that you need to approach the installation of equipment and the choice of welding method as responsibly as possible. You can choose one of several existing types 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 edge groove. The most profitable and economical methods of cutting pipes are oxygen, manual and mechanized.
As you already understand, replacing heating radiators with gas welding is a process that requires preliminary study in theory and then consolidation in practice. But few people, of course, want to train on a real object.
If you contact us for help, you will be able to consult on all your questions, as well as receive information on the approximate cost of replacing heating radiators.
The final estimate can be drawn up by a specialist who will conduct a final assessment of the property in person. And then you will only need to prepare the room for the start of work. To do this, it is better to remove excess furniture and close floor coverings and protect interior parts.
Our specialists will do the rest: deliver materials and equipment, agree on draining the central heating risers, and perform pressure testing of the system.
If desired, you can also order the transfer of radiators and risers to a more convenient location, as well as organize the installation of a boiler in a private house for an autonomous heating solution.
Our company is also distinguished by an individual approach to each client. You will be kept informed of each stage of installation, and your wishes will be taken into account when choosing materials for replacing heating batteries with gas welding. Our specialists are ready to answer every question you have, and the final result will be an effective and reliable solution for heating your home.
I install heating radiators regardless of the location of the old supply pipes.
In addition to the quality of installation, I also pay great attention to the aesthetics of the overall appearance of the connection.
I don't use old pieces of pipe, welded elbows or welded threads... just solid pipe that I bend and thread.
I use a “roller” pipe bender, which guarantees a small radius and a perfectly even pipe bend, regardless of the quality of the pipe being bent.
For packing taps and installing “American” valves, I use anaerobic sealant (guaranteed for the entire service life of the connection without corrosion).
In cases where the installation of taps is done on flax with paste, I roll notches, which guarantees the fixation of the flax and prevents it from being squeezed out.
When welding pipes, I use pipe joining into a socket... based on the requirement
Guaranteed welding without leaking welds the first time. (especially relevant in cases where it is not possible to pressurize the system)
Only high-quality and original materials and time-tested components.
Guarantee of Quality and Aesthetic appearance of all work performed.
and... Good mood for the entire service life of the heating radiators :)
pipe bending: comparison of bends of a roller pipe bender and a hydraulic one + bends with different bend radii... standard and small, which I use in my work
packaging materials: only high-quality anaerobic Loctite sealants and investment materials... Vibra-Tite paste + Geb flax
knurling of notches: additional guarantee from squeezing out flax when screwing and assembling threaded connections
socket welding: guaranteed high-quality welding joint, regardless of the conditions and ease of welding, recommended by SNiP
High-quality and original materials and components: FAR, RB, GEB, Loctite, Vibro-Tite, Fischer
Replacement of heating radiators with gas welding
Installation, installation of one heating radiator with a turnkey pipe bender - from 10,000 rubles
This amount includes... dismantling the old radiator and all the necessary preparatory and installation work: measurements, threading, crane packing, pipe bending.
As a rule, the riser is partially replaced from the floor to the middle of the riser, above the mounting sleeve, including complete replacement horizontal supply pipes. This allows you to achieve horizontal and parallel precision in the location 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, I only purchase the pipe itself, which I bend myself and cut threads only in the right places to install taps at the work site... 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 connection types - from 12,000 rubles
Remove the convector (old radiator) and straighten the heating riser - 6,000 rubles
Approximate time to complete gas welding work -
from about 3 days (it all depends on the complexity and number of radiators)First and second day: arrival and preparatory work for assembling new radiators, attaching brackets and hanging radiators (if possible), taking measurements, bending and cutting pipes, cutting threads and packing valves - the most complete preparation before the final stage of pipe welding.
The third day: turning off and draining the water for the final final stage of work - re-welding the supply pipes.
As a rule, the last stage of welding (including adjustment) takes approximately 1.5 - 2 hours for each radiator.
Re-welding of water supply risers with gas welding
Overcooking of one water supply riser in a straight line (galvanization) - from 15,000 rubles .
Approximate time to complete gas welding work - approximately 3 days (depending on complexity)
First and second day: arrival and preparatory work... preparation of riser rods with welding of new bends, bending of pipes to move risers (if necessary) and packing of taps.
The third day: in the first half of the day, turning off and draining the water for the final, final stage of work... overcooking the risers.
As a rule, to avoid contamination, both water risers (cold and hot) are turned off at the same time... the time it takes to overcook two water supply risers at the same time is approximately 2 hours
Working with frozen pipes
Replacement and installation of one heating radiator with frozen pipes, without disconnecting the heating risers
Time required for freezing pipes- from approximately 3 days (it all depends on the complexity and number of radiators)
It all depends on the complexity of the execution... how many radiators are replaced, so many days of work, taking into account the stages and preparatory work+ installation itself.
As a rule, work occurs in several stages:
1. The most difficult thing... is freezing the riser and dismantling the old convector with a temporary jumper 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 supply pipe blanks.
3. The final stage... re-freezing the riser, with adjustment and final connection of the new heating radiator.
PS. The final price of the work is determined by me only after reviewing the photographs with measurements and understanding the task!
Thermal Imager Inspection
Inspection and identification of heat loss using a Thermal Imager, which allows you to clearly see all defects in the junction of walls and window openings
degree of heating of heating radiators and other cold bridges - 5,000 rubles
PS. in cases of ordering replacement of heating radiators, inspection using a thermal imager... FREE OF CHARGE!!!
Departure, Consultation and Measurements
Visiting the site for inspection, measurements and consultations (at the customer’s request) - 5,000 rubles
PS.Usually, to understand the work, photographs with measurements by mail are enough for me and there is no need for a special visit!!!
This service is for those customers who, for some reason, cannot or do not want to take measurements and it (this service) does not guarantee that I will undertake the fulfillment of your order and in any case it is paid separately, regardless of whether I will fulfill your order or not, since this is primarily a consultation and measurements, according to which in any case I will give you a recommendation and calculation for the selection of radiators, materials and connection diagram.
Transport and other expenses
Purchase and delivery of pipes and components - from 3,000 rubles. (the components and pipes themselves are paid separately)
Also, this amount includes gas refilling (acetylene + oxygen), cleaner + anaerobic sealant, flax with paste and other consumables.
Minimum order:
Due to the technological features of my installation of heating radiators and the need to bring a lot of tools to the site (a whole workshop) + purchase and preparatory work...minimum order from 3 heating radiators or 33,000 rubles
PS. The final price of the work is determined by me only after viewing photos with measurements and understanding the task.
When building a new house or during a major renovation of an apartment, you have to resolve the issue of installing 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 operating system.
There are several options for connecting pipes: replacing heating radiators with gas welding, electric welding or a threaded method. Although each technology has pros and cons, most craftsmen are inclined towards gas welding work. Why? Let's look at it 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 heated in 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 general heating of the house for at least several hours, which is unlikely to please the neighbors
For special weld strength, filler material in the form of wire or rod is used. When the hot metal cools, a monolithic joint is formed.
Advantages and disadvantages of joining pipes by welding
One of the main reasons for the popularity of the gas welding method is the specificity of the work of our heating systems. During circulation, all structural elements are constantly under pressure, which deforms the joints.
Therefore durable Weld reliably protects against breakthroughs and helps prevent accidents during short pressure surges and even, which often accompany the startup and shutdown of centralized heating.
