BW-ZP型直管压力平衡型不锈钢波纹补偿器（膨胀节）由位于两端的两个工作波纹管和位于中间的一个平衡波纹管及拉杆和端板、法兰接管等结构件组成，主要用于吸收轴向位移并能平衡波纹管压力推力的膨胀节。补偿器通过受力构件来承受压力推力，只需固定中间支架，产品只能吸收轴向位移。

BW-ZP straight pipe pressure-balancing stainless steel corrugated compensator is made up of structures as two working bellows at the two ends, a balanced bellows in the middle, pull rod, end-plate and flange connecting pipe etc. It is mainly used to absorb axial displacement and balance the pressure or thrust caused by the bellows. The compensator bears the pressure or thrust as long as fixed the mid supporting frame and it can only absorb axial displacement.
