Since rubber, glass, metal alloys and the like have defects in corrosion resistance, it is difficult to meet the environment in which the temperature, pressure and chemical medium coexist in a harsh condition, and the resulting loss is quite remarkable. The PTFE material has become the main corrosion-resistant material in the petroleum, chemical, textile and other industries due to its excellent corrosion resistance. Specific applications include: conveying pipes for corrosive gases, exhaust pipes, steam pipes, high pressure oil pipes for rolling mills, high and low pressure pipes for aircraft hydraulic systems and cold press systems, rectification towers, heat exchangers, kettles, towers, tanks Lining, valves and other chemical equipment.

    The performance of the seal has a great impact on the efficiency and performance of the entire machine. The PTFE material has corrosion resistance, aging resistance, low friction coefficient and non-stickiness, wide temperature range and good elasticity. It is very suitable for the manufacture of seals with high corrosion resistance and temperature above 100 °C. . Such as machines, heat exchangers, high pressure vessels, large diameter vessels, valves, seals for grooved flanges of pumps, glass reactors, flat flanges, seals for large diameter flanges, shafts, piston rods, valve stems, Worm gears, seals for tie rods, etc.
