Henan Liwei Industry  Co., Ltd. is a professional manufacturer of water supply and drainage materials. Our main products include Single/Double Sphere Rubber Joint, expansion joint, Ball Joint, Flange, steel dismantling joint, Carbon Steel/Stainless Steel Metal Expansion Joints, Fabric Expansion Joints, valve parts, pipe parts, various kinds of stainless steel compensators, duct fabric compensators, advanced soft sealing gate valves and flange butterfly valve.

Non-metallic compensator constitute the main body of their work is non-metallic material, usually fabric, so called fabric compensator or expansion joints.

Based on the high elasticity, high air-tightness and medium resistance of rubber and the flexibility and heat resistance of fiberglass fabrics, non-metallic compensator good overall performance. Non-metallic compensator has advantages such as high temperature resistance, corrosion resistance, logical structure, simple installation and maintenance.

 Non-metallic compensator  is designed with short metal pipes and flanges connection with fan and air duct on two ends so as to compensate for the thermal expansion needed by operating air duct and for the displacements.

In many engineering fields, non-metallic compensator is widely applied. Working pressure is not high ventilation, dust and smoke, and air conditioning pipe insulation equipment commonly used non-metallic compensator. Non-metallic compensator is widely used in steel mills, smelters, petrochemical plants, power plants, cement plants and atomic power plant flue gas desulphurization and dust removal equipment, air heating, flow blower and other equipment at the entrance, which are much better than metal retractable Festival, it won a good reputation from users, been vigorously promoted by the users.
