BW-WP型弯管压力平衡型不锈钢波纹补偿器（膨胀节）由一个工作波纹管或中间管所连接的两个工作波纹管和一个平衡波纹管及弯头或三通、封头、拉杆、端板和球面与锥面垫圈等结构件组成，主要用于吸收轴向与横向组合位移并能平衡波纹管压力推力的膨胀节。工作波纹管吸收来自弯管段产生的横向位移：平衡波纹管吸收来自直管段的轴向位移。当弯管段产生横向位移，拉杆上球面螺母绕球面垫圈转动，同时拉杆承受内压力推力。

BW-WP curved pipe pressure-balancing stainless steel corrugated compensator is made up of structures as two working bellows, which is connected by a working bellows or a mid pipe, and a balanced bellows , ball joint or triple joint, closed joint, pull rod, end-plate, spheri-cal or cone-shaped washer etc. It is a compensator used to absorb composite axial and transverse displacement and can balance the press-ure and thrust of the bellows. Working bellows absorbs the transverse displacement caused by the curved part of the pipe while the balanced bellows absorbs the axial caused by the straight. When the curved part produces transverse displacement, the spherical nut on the pull rod rotates around the washer and the pull rod bears the inner pressure or thrust.
