By-pass Pressure Balanced Expansion Joints

Products


	[Structural Features] This type of expansion joints consists of two bellows with the same diameter and the same effective area, one sleeve and some other components. The working bellow bears the internal pressure while the balance bellow bears the external pressure. The piping and the equipment only carry the rigid counter-force caused by the movements of expansion joints instead of the axial thrust caused by internal pressurization. This balanced type of expansion joints is suitable for where the fixed support cannot be set between the two equipments because of its good self-guidance, economy and non-directional requirement of installing.
