Profile: Pickup Bellows Ltd. manufactures bellows expansion joints. They are used in the oil, petrochemical, power-generation, marine, heating, diesel, steel and mineral processing industries. Restrained expansion joints are normally designed to contain the loadings due to end thrust without any change in length by means of tie bars or hinges. Therefore, the loads imposed on system anchors are considerably lower than for unrestrained type expansion joints, as the internal pressure thrust produced by expansion joints is retained by the integral bracketry.
