Rubber ball-steel wire reinforced rubber
Used for axial length compensation on the pipe. In order to prevent exceeding the allowable compensation amount, a protective pull rod or a guard ring is disposed at both ends of the bellows, and a guide bracket is disposed on the pipe at both ends to which it is coupled.
There are also corner and transverse expansion joints that can be used to compensate for corner and lateral deformation of the pipe.
The advantages of this type of expansion joint are space saving, material saving, standardization and mass production, and the disadvantage is that the life is short. Bellows expansion joints are generally used on pipes with low temperature and pressure and short length. With the increasing level of corrugated pipe production technology, the application range of such expansion joints is expanding.
