The corrugated compensator also has a corner and a transverse expansion joint that can be used to compensate for corner deformation and lateral deformation of the pipe. The advantages of this type of corrugated compensator are space saving, material saving, standardization and mass production, and the disadvantage is that the life is short. Corrugated compensators are generally used on pipes with low temperature and pressure and short length. With the improvement of the production technology of corrugated pipes, the application range of such corrugated compensators is expanding.
