Spiral wound gasket is "V" stainless steel band with a different sandwich filling material requirements made by the winding, depending on working conditions, pressure conditions, the structure can take to strengthen the inner, outer, gaskets to increase membership installation, use of compressive strength and rigidity, the formation can be divided into basic, inner type, the outer ring type, inside and outside the ring of four. The main structure of gasket material made of metal frame, so the high strength, rigidity and good resistance to high pressure, high temperature resistance, excellent flexibility and compensation for bearing capacity, good sealing performance. Mainly used in chemical, petrochemical, oil, thermal power, metallurgy, nuclear energy, aerospace, machinery, shipbuilding and other fields of various pipes, container, tower type, reactors, evaporators, condensers, boilers, pumps, valves and other law Lan connection for static sealing components for use, due to the applicability of the gasket, can withstand intense pressure and temperatures alternating load, so common in the industrial field of application, covering a wide range.
Material of Outer ring or inner ring: Carbon steel, SS304, SS316, SS316L, Hast C. etc.
Material of Filler: Graphite, PTFE, etc
Standard: ASME B16.20
