External-Pressure Straight-Pipe Pressuer-Balanced Expansion Joint-Henan Kaida Bellows Co., Ltd.

External-Pressure Straight-Pipe Pressuer-Balanced Expansion Joint

An externally pressurized, straight-pipe pressure-balanced bellows expansion joint designed to accommodate axial movement and reduce pressure-thrust loads transmitted to the piping system. The external-pressure arrangement also supports stable bellows operation where greater axial movement capacity is required.
