Structural Features
The axial internal pressure expansion joint is composed of a bellows and two end pipes. The end pipe is either directly welded to the pipe, or welded to the flange and then connected to the pipe flange. It is mainly used to compensate for the axial displacement. Compensating for the lateral displacement or the combined displacement of the axial and lateral directions has the ability to compensate for the angular displacement, but it is generally not used to compensate for the angular displacement.
The tie rod is mainly used for rigid support during transportation or used for product pre-deformation adjustment. It is not a load-bearing part
