[Structural Features]

This type of bellow expansion joints consist of one bellow, hinge pins, hinge plates, vertical plates and some other components. Simplex hinged bellow expansion joints don’t work alone but usually two or three of them are combined together to be put into use. Movements of the angle pipes are compensated by angular deflection. The hinge, hinge pin and hinge plate can carry thrust and other additional external force. Only angular movements in a single plane can be absorbed.
