Metal spiral wound gasket high quality SUS304, SUS316 ("V" shaped or "W"-shaped) metal band, and other alloys and graphite, asbestos, PTFE, asbestos and other soft materials are alternately overlapping spiral wound made start and end with a spot in the way of the metal straps. Metal spiral wound gasket for the semi-metallic resilient gasket in the best gaskets, spiral wound gasket structure density can be based on different locking force required to produce and use both inside and outside steel ring to control the maximum degree of compaction, winding gasket contact surface of flange sealing surface less precision. Metal spiral wound gasket especially for uneven loads, engaging force easy to relax, cyclical changes in temperature and pressure, there is shock or vibration occasions. Spiral wound gasket is valves, pumps, heat exchangers, towers, manholes, hand holes and other flange static sealing treatment like originals.

Excellent elasticity spiral wound gasket pressure piping system capable of thermal cycling and vibration automatic adjustment, especially for non-uniform load, easy to relax the engaging force, temperature and pressure changes periodically, where there is an impact or vibration. Are valves, pumps, heat exchangers, towers, manholes, hand holes and other static sealing flange connections originals widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and space sectors.
