Flexible Expansion Joint For Pipeline Thermal Displacement Compensation And Vibration Absorption

The Gimbal Expansion Joint (Universal Hinged / Universal Tied Type) absorbs multi-plane angular movement while restraining pressure thrust. Its tied version, similar to a Tied Universal Expansion Joint, also handles lateral movement, making it ideal for complex high-temperature piping systems.

Hinged Expansion Joint (Single Gimbal / Angular Type) allows single-plane angular rotation while its hinge assembly restrains pressure thrust. Used in pairs for L- or Z-shaped piping, it suits high-temperature ducts and pipelines. Unlike a Tied Universal Expansion Joint, it cannot absorb lateral movement.

The Double-bellows Expansion Joint uses twin stainless steel bellows, an intermediate pipe and load-bearing rods to absorb lateral and limited angular movement while restraining pressure thrust. Available in DN50–DN6000, PN0.25–PN25 and -196°C to 450°C; it cannot absorb axial displacement.

The Single-bellows Expansion Joint absorbs axial thermal expansion in straight piping. Made with stainless steel bellows and welded or flanged ends, it supports DN25–DN6000, PN0.25–PN16 and -196°C to 450°C service. Fixed and guide supports are required for safe operation.
