Because the
corrugated tooth composite gasket has the dual function of toothed metal seal and non-metallic shrinkage graphite seal, and its sealing band is completely separated, it has a particularly excellent sealing performance. The air tightness test shows that the
corrugated tooth composite gasket The gasket can not only achieve extremely high sealing under 35MPa compression (leakage rate can reach 10-5cm3/s level).
It still has excellent sealing performance under low pressure, and the air tightness can still reach the level of 10-3cm3/s at a specific pressure of 15MPa (the standard rule for asbestos rubber sheet is only 10-2cm3/S), with excellent rebound performance and long sealing life. , Because the corrugated composite gasket has a special structure of the corrugated elastic skeleton and the metal and shrinkable graphite materials that constitute the composite gasket have excellent high temperature resistance, fluid corrosion resistance, and will not age.
The elasticity of the gasket is mainly produced by the metal skeleton of the special structure, and there is no need to worry about stress relaxation during use, so it can maintain excellent sealing performance for a long time. Safe and reliable. When the
corrugated tooth composite gasket is used, the annular tooth peak of the metal skeleton is in close contact with the flange surface, and the shrinkable graphite material is blocked by the solid metal skeleton and the flange surface, so there is no need to worry that the shrinkable graphite material will be washed away by the high-pressure fluid.
Don't worry about "falling apart" or "crushing" ("buckling") like spiral wound gaskets. Corrugated composite gaskets actually have the same safety and reliability as metal gaskets. Easy to use device. The overall structure of the corrugated composite gasket is tied with a metal frame, so there is no need to worry about "falling apart" like a wound gasket during transportation and application. In addition, the thickness of the corrugated composite gasket is relatively thin (usually 2~4mm).
