The旁通压力平衡式膨胀 joints are primarily used in situations where fixed supports are not required. They effectively protect equipment and pipelines from deformation, and are applied in the connections of smelting, power plants, industrial equipment manufacturing, and engineering pipeline systems. They ensure the safety of pressure pipelines during the transportation of media, preventing leaks.
The旁通压力平衡式膨胀节 possesses the capability to absorb internal pressure thrust and features excellent directional properties, small stiffness, and compact dimensions.

The bypass pressure balancing expansion joints are categorized into single bypass pressure balancing type and double bypass pressure balancing type, both utilizing the same specification bellows. They feature small volume, low cost, good guidance, and excellent stability.

The bypass pressure-balanced expansion joint consists of a working wave under internal pressure and a balancing wave under external pressure, featuring a compact design. Its number of instability waves is twice that of a straight pipe pressure-balanced compensator, as the two intermediate bellows are subjected to external pressure, resulting in better stability. It is mainly used for expansion joints that can absorb combined axial and lateral displacements and balance the pressure thrust of the bellows.

The旁通压力平衡型膨胀节 is primarily used to absorb axial displacement and balance the pressure thrust of the bellows, with the internal pressure thrust load being balanced and supported by its own components. It is suitable for applications where significant thrust is not permitted.

The connection method of the bypass pressure balance type expansion joint: Flange / Welding
