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.
The octagonal gasket is a solid metal gasket with an octagonal cross-sectional shape by forging, heat treatment and machining of metal materials. It has a radial self-tight sealing effect. It depends on the contact between the gasket and the inner and outer surfaces (mainly the outer side) of the flange trapezoidal groove, and is pressed to form a seal. The general materials used are: carbon steel, stainless steel 304, 316, etc.
