Fabric compensator, also known as non-metallic compensator, non-metallic expansion joint or non-metallic expansion joint, is a kind of equipment used to absorb and compensate for the displacement and stress in piping system caused by temperature change, pressure fluctuation or mechanical movement. Non-metallic compensator is used to compensate for axial, transverse and angular displacements in piping systems, which is greatly superior to metallic compensators that can only compensate in a single way.

Structural components

Metal frame: as a support structure, usually made of stainless steel or galvanized steel, with good corrosion resistance and mechanical strength, to ensure the stable operation of the compensator in harsh environments.

Fiber fabric skin: this is the core part of the compensator, using high strength, high temperature, corrosion-resistant special fiber materials woven, such as polytetrafluoroethylene, glass fiber and so on. These materials not only have good flexibility, but also can withstand certain pressure and temperature changes, and its role is to absorb the expansion to prevent air leakage and rainwater leakage.

Realization of free expansion and deflection of the piping system

Necessary accessories: including metal ring band, heat insulation material, etc. These accessories enhance the performance and application range of the compensator.

Application Scenarios

Hot air ducts: suitable for high temperature hot air ducts due to its high temperature resistance and corrosion resistance.

Smoke and dust piping: able to effectively reduce vibration and noise, suitable for smoke and dust piping.

Boiler and fan system: it can reduce the noise and vibration of the system and improve the stability of system operation.‌‌
