The gasket is manufactured by spirally winding a "V"-shaped metal strip and flexible graphite alternately, then assembling an outer ring onto the gasket body (a metal-wound gasket body with an inner ring). This product is suitable for sealing flange connections in pipelines, valves, pressure vessels, condensers, heat exchangers, towers, manholes, handholes, and similar applications in industries such as petroleum, chemical, metallurgy, power, shipbuilding, and machinery.
