Aramid carbon fiber packing has the wear resistance of aramid and the high temperature resistance of carbon fiber. The two materials are mixed to achieve the ideal effect of bisexuality. The sealed aramid packing of machinery, pumps, valves, pipes, containers, etc. used in the installation of fluid conveying equipment with particles and its medium, steam, organic solvent, acid, alkali and other fluid conveying equipment has excellent smoothness and wear resistance.
Synthetic slate is a composite material made of high-temperature nanofiber felt and high-performance epoxy resin, which has the characteristics of low thermal conductivity, resistance, high temperature resistance, anti-static, light weight, and chemical resistance.
This kind of metal ring gasket is made of metal material by forging, heat treatment and machining into a solid metal gasket with an elliptical cross-sectional shape. It has a radial self-sealing effect and is a standard R-type metal ring gasket. The principle of action is to rely on the contact between the gasket and the inner and outer surfaces (mainly the outer side) of the flange trapezoidal groove, and to form a sealing effect by pressing.
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).
The PTFE gasket has the characteristics of acid resistance, alkali resistance, high temperature resistance and resistance to various organic solvents.
Metal spiral wound gaskets can be made of flexible graphite, asbestos, PTFE and other stainless steel, copper, carbon steel and other metal materials. Working temperature: -200~650℃, working pressure: 3.5MPa, main use: suitable for pumps, valves, heat exchangers and pipes, flanges, valves, pump inlets and outlets, heat exchangers, reaction towers, query holes, hand Holes, high temperature, high pressure steam, oil and gas, solvent, gas, heat transfer medium, etc. are one of the important parts of flange sealing.
