The spiral wound gasket utilizes the heat resistance, resilience and strength of the metal and the softness of the non-metallic material (graphite, PTFE, non-asbestos, mica, ceramic fiber, vermiculite), so the denseness is good, and the stainless steel strip is wound. Flexible graphite mats perform best. The inner and outer ring materials of the spiral wound gasket are SS304, SS316, SS321, Duplex, Ttitanium, Inconel, Monel and so on.
Spiral wound gasket are suitable for heat exchangers, pressure vessels, pipes, valves, condensers, manholes, hand holes, pump inlet and outlet flanges with large temperature and pressure fluctuations, in chemical, petrochemical, electric power, shipbuilding, machinery. And natural gas and other fields have a wide range of applications.
The inner and outer rings of the spiral wound gasket are processed by the most advanced laser cutting, CNC punching. The inner and outer ring grooves of the spiral wound gasket have a common v-shape and a special w-shaped structure.
