The connecting branch pipe can be made of ordinary galvanized or alloyed steel, silicon-manganese grades 09Г2С, 09Г2ДТ, 09Г2Т, stainless steel ст 20 are actual. All axial expansion joints for welding differ in the following parameters:

· Range of working stroke;

· Internal section;

· Limiting pressure;

· The limiting operating temperature ;;

· Type of connecting fittings.

At the request of the demandor, a waterproofing or anticorrosive layer is applied to the outer part of the casing and the connecting fittings of the compensator.

Application of

Compensators for welding serve to compensate for thermal expansion or inaccuracies in mounting on straight sections of pipeline systems of water heating, pumping installations, heating systems and similar structures. These devices are in many ways superior to other varieties of expansion joints. In addition to performing the basic tasks, this device facilitates the construction and commissioning of heating systems, reduces the loss of thermal energy.


· Effective compensation of temperature expansion and vibrations;

· Optimization of pipeline layout;

· Reduction of metal consumption of the pipeline contour;

· Extension of pipeline operation;

· Compliance with the maximum performance of pipelines at pressures up to 125 kg / cm 2 and temperatures from cryogenic to + 450 ° C;

Can be used in circulating systems for water, gas, steam, oil products, refrigerants, etc.


Axial expansion joints for welding are referred to as non-remountable devices. But for 30 years they do not require maintenance or replacement.
