Rubber-cloth expansion joints are designed to prevent possible gas leakage in the areas of stress of medium and low pressure underground gas pipelines, in areas with increased seismic activity as well as in areas which are exposed to soil movement under pressure from mine workings, landslides, etc.
Compensators are installed at the joints of gas pipes at a distance of 30-100 meters from each other and work on tension, compression and bending in conditions of constant contact with natural gas preventing gusting of gas pipelines.
Main technical characteristics.
- Compensating ability for compression-stretching - up to 150 mm. (counting from the normal unstressed state). - Working environment - natural gas - Operating temperature range is from -30 to + 40 ° C. - Working pressure - 3 kg / cm2 - Type of connection with the pipe - flanged according to GOST 12827
An example of the designation of the compensators "KS-150" where KS is the type of compensator (medium pressure),150 - diameter of the nominal passage, mm.
