Are steel rings used as valve sealing surfaces? If so, in what occasions are they used?
There is, right? . A hard seal uses a metal seal. . . When temperature and pressure are high, soft seals cannot be used, so hard seals are adopted instead
Can wave-patterned composite gaskets also withstand high temperatures? Moreover, its sealing performance should be better than that of a steel ring; why not use a wave-patterned composite gasket?
Steel ring? Are you referring to metal-graphite wound gaskets? Used for high temperature and high pressure
Sure. But attention should be paid to the choice of materials. For example, FEMA’s low-pressure safety valves use 316L valve seats without any cemented carbide coating. However, there is a problem with the lifespan.
Is it an RJ sealing surface? An 8-corner pad is just a steel ring
