Model: DN600-DN4000, pressure level 0.25 MPa-0.6 MPa. Connection modes: 1, flange connection type 2, nozzle connection type Axial compensation: 60mm-300mm. Usage: Each end of the expansion joint has a working bellows, and there is a Balanced Bellows in the middle. The expansion joint can withstand internal pressure thrust through a force-bearing member (large tie rod or tongue tube). Therefore, only the intermediate fixing bracket is needed for the piping system. Such expansion joints can only absorb axial displacement.
