Bellows expansion joints with a corrugated metal tubing expansion joints. Stretching it along to the pipe axis, also allows a small amount of bending. Common Axial bellows expansion joints with axial length compensation in the pipeline. To avoid exceeding the allowable amount of compensation, the bellows are provided at both ends of the rod or the protection of the protection ring disposed on both ends of the pipe guide bracket connected to it. Another angle type and horizontal-type expansion joints angle to compensate for the pipeline deformation and lateral deformation. Advantages of this type of expansion joint is a space-saving, material saving, ease of standardization and mass production. Bellows expansion joints are generally used for temperature and pressure is not high on the short length of pipe. With the improvement of the bellows production technology, this kind of expansion joints range of applications is expanding. Currently, bellows expansion joints used in piping maximum pressure of 6.0 MPa.
