The structure of metal spiral wound gasket products is relatively straightforward, making it easier for manufacturers to operate in projects. The structural density of metal spiral wound gaskets can be manufactured according to different clamping force requirements, with the steel rings in the table used to control their high clamping force. The surface accuracy of the flange sealing surface in contact with the spiral wound gasket is not high. Metal spiral wound gaskets are particularly suitable for applications with uneven loads, prone to relaxation, varying temperature and pressure conditions, impacts, or vibrations.
The basic type of metal spiral wound gasket is an ideal static seal for flange connections such as gate valves, pumps, heat exchangers, towers, manholes, and handholes. Another benefit is that it is not easily damaged or contaminated over time during installation and removal. During the actual application period, it will not cause harm to other components. It is also used on Japanese aircraft carriers without corroding the flange sealing surface and has higher strength.
Metal coated gaskets are made of stainless steel, copper, carbon steel, and other metallic materials coated with flexible graphite, asbestos, PTFE, etc. Operating temperature range: -200~650°C, working pressure: 3.5 MPa. Application scope: suitable for pumps, valves, heat exchangers, and various flange seals. Pipelines, flanges, gate valves, pump inlets and outlets, heat exchangers, reaction towers, inspection holes, handholes, high-temperature and high-pressure steam, oil and gas, solvents, gases, heat transfer media, etc. Sealing of casing covers, etc.
Metal spiral wound gaskets are made of stainless steel strips, flexible graphite strips or asbestos strips, PTFE strips, and other laminated windings with welded joints. Application areas of metal spiral wound gaskets: sealing of flange connections for pipelines, gate valves, pressure vessels, coolers, heat exchangers, towers, manholes, handholes, etc., in industries such as crude oil, chemicals, metallurgy, electric power, shipping, and machinery. The structural density of metal spiral wound gaskets can be manufactured according to different clamping force requirements.
The steel rings in the table are used to control their high clamping force, and the surface accuracy of the flange sealing surface is not strictly required. Metal spiral wound gaskets are particularly suitable for applications with uneven loads, relaxed joint forces, varying temperature and pressure conditions, impacts, or vibrations. Spiral wound gaskets are ideal static seals for flange connections such as gate valves, pumps, heat exchangers, towers, manholes, and handholes.
