Axial movement of a 321 stainless steel corrugated compensator is considered an extension or compression of the piping system on its longitudinal axis, which means that the overall length of the expansion joint will extend or compress during the absorbing movement. Axial expansion joints designed to absorb larger movements can contain one, two or more bellows in a single unit and can also achieve greater movement by pre-tensioning or installing multiple expansion joints on pipe sections . . Depending on the nominal diameter and length, 321 bellows expansion joints are able to absorb small lateral and angular deviations as well as installation tolerances.
The 321 stainless steel corrugated compensator consists of the bellows (elastic element) of the main body and accessories such as end pipes, brackets, flanges and conduits. It has excellent flexibility, corrosion resistance, ultra-high temperature and high pressure resistance. It can be connected in any direction of the pipeline to compensate for temperature and absorb vibration, reduce noise, change the direction of medium transmission, eliminate mechanical displacement between pipelines or between pipelines and equipment, etc.
