Fabric Rectangular Expansion Joint
The rectangular non-metallic compensator is a flexible component consisting of a composite non-metal mateiral,two pipes (or flanges) connected to adjacent pipeline and insulation materials.It is mainly used to compensate for the displacement caused by temperature, mechanical vibration, and foundation sinking in pipelines and equipment systems that transport micro-pressure dust gas, smoke, gas, and other gases.Pressure range:≤0.05 Mpa;Temperature range: low temperature type ≤200°C, high temperature type ≤ 800°C; Diameter range:Any sizes.
