Name: SF steel expansion joints
expansion joints role: SF steel expansion joints, also known as expansion joints, expansion joints, compensators, divided into: bellows, sleeve compensator, rotating compensator, square and other major natural compensator type, which ripple compensator is more commonly used, mainly for the protection of the safe operation of pipelines, steel expansion joints have the following effects: 1. Compensation for absorption pipe axial, lateral, angular to heat distortion. 2 vibration absorption device, reducing equipment vibration impact of the pipeline. 3 absorb earthquake, subsidence of the pipeline deformation.
