Spiral wound gasket Compression performance, rebound performance is good, with multi-channel seals and a certain degree of self tightening function, for flange pressure surface defects are not too sensitive, not bonded flange sealing surface, Can partially eliminate the pressure. Temperature change and mechanical vibration influence; can at high temperature. Low temperature, high vacuum. Under various harsh conditions, such as impact vibration, it keeps its excellent sealing performance. Use of equipment: petroleum, chemical, metallurgy, electricity, shipbuilding, gas, nuclear power, aerospace, textile, medicine, machinery and other industries pipelines, valves, pressure vessels, condensers, heat exchangers, towers, manhole, hand holes and other flange joints at the static seal parts.
