I 、 PTFE Compensator
Application:PRFE compensator (also callede PTFEexpansion joint) is used in the piping system of strong corrosive media for compensationg of displacement and installation deviation aroused by expanding with heat contracting with cold.to reduce shock of piping system.

 Flange connection can be determined as perusers' requirements.
 II.Flexible Rubber Damping Expansion Joint
ApplicationL:This joint is installed on pipeline to absorb shock,reduce noise,and eliminate offset of pipiline.Damage of various forces to pipeline generated by distortion of medium can be diverted whereupon.and it is normally used at the inlet and outlet of the pumps.
