Teflon gasketIt is a polymer compound made by the polymerization of tetrafluoroethylene. It has excellent chemical stability and corrosion resistance. It is one of the best corrosion-resistant materials in the world today. Except for molten sodium and liquid fluorine, boiling in water is unchanged.
IfTeflon gasketWith sufficient resilience, so that the working sealing pressure on the sealing surface is always greater than that of the medium and the working pressure, the sealing surface maintains a good sealing state. The necessary conditions for forced sealing are medium and working pressure. Under the action of force, the sealing surface can still maintain a certain pressing force.
Teflon gasketWhen forced sealing, the medium pressure always tends to reduce the pre-tightening seal specific pressure and reduce the sealing performance. forced sealingTeflon gasketThe typical structure of the flat gasket, wound gasket and tooth gasket, etc., are usually used for low pressure, medium pressure and medium and small diameter valves.
Everyone is sealed.Teflon gasketAt the same time, it is necessary to meet its sealing conditions so as to better maintain it.Teflon gasketLonger service life.
Teflon gasketThe working conditions of the seal are relatively stubborn, the thermal deformation is large, and it is often subjected to vibration, impact, improper installation, excessive tightening force, repeated application, shrinkage deformation, internal stress concentration,Damage exceeding the fatigue strength, data aging, conversion, etc. will cause damage and leakage. This kind of leakage has great influence and harm, so we must strengthen prevention.
Teflon gasketIt is suitable for sealing parts with drastic temperature and pressure changes. It is a static sealing element for flange connection of pipelines, valves, pumps, heat exchangers, towers, manholes, hand holes, etc. By changing the tension of the wound steel strip, the density of the wound gasket can be changed(hardness) to meet the needs of various applications. Widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy, aerospace and other industries.
