<\/p>\nSpiral wound gaskets are engineered for high-temperature, high-pressure sealing in oil, chemical, power, and metallurgical industries. They are widely used in flanged connections of pipelines, valves, pumps, pressure vessels, and heat exchangers. The combination of metal winding and flexible filler provides excellent elasticity, mechanical strength, and chemical compatibility, ensuring reliable sealing even in extreme conditions.<\/p>\n

Spiral wound gaskets are high-performance sealing components made by winding alternating layers of metal strips and soft filler materials<\/strong> (such as graphite or PTFE) into a spiral shape, designed to provide reliable sealing under high pressure and temperature.<\/p>\n
They typically consist of stainless steel, carbon steel, or alloy metals<\/strong> for the winding, combined with fillers like graphite, PTFE, or ceramic<\/strong> to enhance sealing performance and chemical resistance.<\/p>\n
They are widely used in oil & gas, petrochemical, power generation, chemical processing, and pipeline systems<\/strong>, especially in flanged joints and pressure vessels.<\/p>\n\n
Selection depends on factors such as operating pressure, temperature, flange type, chemical compatibility, and gasket size<\/strong>, ensuring optimal sealing and safety in the application.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>","protected":false},"excerpt":{"rendered":"
