External Pressurized Axial Expansion Joint

The external pressurized axial expansion joint consists of an inner tube, bellows, outer tube, and associated components. The bellows, subjected to external pressure, has good sealing and bending resistance, and can absorb large displacement. It can be made in single, universal, or bidirectional forms. The external pressurized axial bellows expansion joint mainly absorbs axial displacement, with the advantages of large compensation capacity, good performance of thermal insulation , and the ability to eliminate residual media.
