Metal Bellows, Expansion Joint & Flexible Joint

Based on latest EJMA Standard, 1998 7th ed, and according to the type of movement in pipeline, connectors and working pressure, we provide several series of Expansion Joints:

§ Axial Movement: JF150 series, JF250 series, JF400 series, JF1000 series, JF500HE series
§ Lateral Movement: JF800 series
§ Axial and Lateral Movement: JF850 series
§ Angular Movement: JF100 series
§ Flexible Joint used to reduce vibration in pipeline: JF500 series
§ Metal Hose: Omega type, braided or non-braided, fitted with flange, weld ends, or screwed male ends, etc.: JF600 series

Stainless steel expansion joints are suitable for compensating for the displacement of general piping during thermal expansion or contraction. Stainless steel flexible joints isolate vibration and reduce noise.
