/>< : >Metal spiral wound gaskets are an important sealing component and are widely used in petrochemical, metallurgical, power generation, shipbuilding and other industries. They are currently a key component for the static sealing of pressure pipelines, valves, pumps, heat exchangers and other equipment in my country. Therefore, it is of great significance to select and use high-quality metal spiral gasket products to reduce and eliminate leakage and ensure the safe and normal operation of the host equipment and pressure pipelines. How to choose metal spiral wound gaskets?
rr rr :% >< : >Metal spiral wound gaskets are made of high-quality alloy belts or stainless steel belts, with graphite, asbestos, and PTFE as filling materials, and are spirally wound in alternate shapes.

< : >Used in petrochemical machinery, metallurgy, electric power, shipbuilding and pipelines, valves, pumps and pressure vessels Flange connections such as condenser tower manholes and hand holes are used for static sealing. Due to its high mechanical strength, easy use and good compression resilience, it is more suitable for applications in severe temperature alternations.
