Non-metallic compensator / flexible fabric expansion joint selection

Non-metallic compensator / flexible fabric expansion joint selection
Non-metallic expansion joint ring belt mainly has non-alkali glass wire fabric, rubber, polytetrafluoroethylene, aluminum silicate mineral wool and other non-metallic production, with the ability to compensate and absorb the expansion and contraction deformation of the pipeline, it has no elastic reaction force compared with the metal compensator, absorbing expansion, vibration and noise reduction, low appearance temperature, easy to install and change, cheap and other advantages. Is designed according to the gas turbine exhaust flue, large boiler flue duct and cement, metallurgy, petrochemical, gas, gas and other industrial characteristics, mainly adapted to the transport of slightly pressurized dust gas, smoke, gas and other media pipeline equipment system due to temperature changes, mechanical vibration and foundation subsidence caused by the displacement compensation, is a, multi-purpose composite material new products.
Installation precautions for non-metallic expansion joints:
1 . When installing non-metallic expansion joints, care should be taken to keep the compensator in its natural state and not artificially deformed.
2 . Installation process, if welding, pay attention to protect the insulation layer of the compensator, especially the outer skin of the product is easily ignited by the shedding of welding slag.
3 . Although the non-metallic expansion joint has no fear of temperature, but in the process of installation and use, pay attention to prevent open flame ignition.
4 . Users in the purchase of the compensator before, to consider the high temperature of fear of temperature. Low-temperature non-metallic expansion joint is mainly used by the material is silicone cloth skin, high-temperature non-metallic expansion joint is mainly used by the material is fluorine rubber cloth skin.
5 . When using non-metallic expansion joints in the desulfurization tower, pay attention to do protection; when used in high friction environment, to change the skin regularly.
