It absorbs the expansion and contraction caused by thermal expansion, vibration, and wind pressure in plant piping.

This product is a composite material made of PTFE (polytetrafluoroethylene) and glass cloth. It is used in combination with other materials as a non-metallic expansion joint material, absorbing the expansion caused by thermal expansion, vibration, and wind pressure in piping joints at steel mills, thermal power plants, and waste incineration plants. The material consists of PTFE sheets and glass cloth composites. 【Features】 ■ Vibration absorption… Absorbs vibrations from equipment ■ Chemical resistance… PTFE has excellent chemical resistance and is suitable for corrosive gases such as exhaust gases ■ Flexibility… The material has excellent bendability and absorbs displacements such as twisting *For more details, please refer to the PDF document or feel free to contact us.
