Baoji metal spiral wound gasket manufacturer / Hanzhong metal spiral wound gasket manufacturer

Baoji metal spiral wound gasket manufacturer / Hanzhong metal spiral wound gasket spiral wound gasket manufacturer of high quality SUS304, SUS316 ("V" shaped or "W" shape) metal band and other alloys and graphite, asbestos, PTFE, non-asbestos and other soft materials are alternately overlapping spiral wound made at the beginning and the end with a spot welding metal straps. Metal spiral wound gasket for the semi-metallic gasket resilience in the best gaskets, spiral wound gasket structure density requirements based on different locking force to make and use inside and outside the steel ring to control the maximum degree of compaction, winding less precision gasket contact surface of the flange sealing surface. Spiral wound gasket especially suitable for uneven loading, easy to relax bonding force, temperature and pressure changes periodically with shock or vibration of the occasion. Spiral wound gasket is valves, pumps, heat exchangers, towers, manholes, hand holes and other flange handle to the original static sealing. Back to the good elasticity of spiral wound gasket pressure piping system capable of thermal cycling and vibration automatic adjustment, especially for uneven loading, easy to relax bonding force, temperature and pressure changes periodically, there is shock or vibration of the occasion. A static seal original, widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and space sectors valves, pumps, heat exchangers, towers, manholes, hand holes and other flange connection. Spiral wound gasket materials of construction: inner outer asbestos filler strip wound wound graphite carbon steel SUS 304 SUS 316 SUS 304 SUS 304 tetrafluoroethylene wound SUS 316L SUS 316 SUS 316 SUS 316L SUS 316L filler temperature??
