PN10 PN16 PN25 Carbon Steel Hinged Expansion Joint Bellows Compensator

Hinged Bellows Compensator

Product description

Working principles of universal hinged type expansion joints are almost the same as that of simplex hinged bellow expansion joints. Universal hinged type expansion joints consist of one bellow and hinge plates connected with four groups of end pipes and gimbal ring, and flexibility components made of two pairs of hinge pins. The hinge plates face to face and they are perpendicular to the gimbal ring so it can absorb angular movements in any plane. Just as simplex hinged bellow expansion joints, SWJ don’t work alone but usually two or three of them are combined together to be put into use. It is used to compensate deflection movements of Z spatial pipe line. The hinge, hinge pin and hinge plate can carry thrust and some other additional external force.
