Description: Elbow pressure balanced expansion joint is composed of a working bellows or two working bellows connected by an intermediate pipe and a balanced bellows and elbow or tee, head, tie rod, end plate, spherical and tapered washer and other structures. It is mainly used to absorb the combined axial and lateral displacement and can balance the pressure and thrust of the bellows. Usually, the pipeline expansion joint is a constrained general-purpose type that can accept lateral movement. Because there is also axial deflection, pressure balanced elbows are usually required. Feature: Absorbs axial and lateral movements Eliminates main anchors Minimum guiding required Pressure forces remain in balance No volume change Balance-pressure thrust remains constant Application: Elbow pressure balanced expansion joints are used in pipelines with a change of direction. Elbow pressure balanced expansion joints are used with low pressure turbines, with condensers and also with pumps and other equipment, that may be susceptible to pressure loads.
