Teflon gasket is a semi-metallic flat gasket made of v-shaped or w-shaped thin steel strip spirally wound with filler material Teflon. By changing the material combination of the gasket, it can solve the problem of chemical corrosion of the gasket by various media. This gasket has good compression resilience, multi-channel sealing and certain self-tightening function, which can partially eliminate the effect of pressure, temperature change and mechanical vibration.
It does not bond to the flange surface and is convenient for maintenance and replacement. It can maintain its excellent sealing performance under high temperature, low temperature, high vacuum, shock vibration and other cyclic alternation and various harsh conditions.
Suitable for sealing parts with drastic temperature and pressure alternation, it is a static sealing element for flange joints of pipes, valves, pumps, heat exchangers, towers, manholes, hand holes, etc. The density (hardness) of the wound gasket can be changed by varying the tensioning force of the wound steel band to meet the needs of each application part, which is widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace industries.
PTFE gaskets are weather resistant and PTFE has the best aging life among plastics. PTFE gasket itself has high resistance to erosion, unstable physical function and high and low temperature resistance, which accomplishes its good sealing function and has been widely used in petroleum, chemical, pharmaceutical, electric power and steel industries.
PTFE gaskets are non-adhesive, PTFE has the smallest surface tension among solid materials and does not adhere to any substance.
PTFE gasket is low temperature resistant and has good mechanical toughness; even if the temperature drops to -196℃, it can maintain 5% elongation. It is suitable for sealing parts where the temperature and pressure change drastically, and is a static sealing element in flange joints of pipes, valves, pumps, heat exchangers, towers, manholes, hand holes, etc.
PTFE gasket itself has high erosion resistance, unrestrained physical function and high and low temperature resistance, which makes it a good sealing function. The density (hardness) of the wrap-around gasket can be changed by varying the tensioning force of the wrap-around steel band to meet the needs of each application, which is widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace industries.
The above is about the use and application of PTFE gasket, which does not add any adhesive in the processing and does not deform, has good flexibility, easy to install and has unique design style.
