  Product Overview: There are four types of sprial wound gasket: the basic type, the inner ring, the outer ring, and the inner&outer ring. Its widely used in electric power plant, chemical industry, chemical fertilizer plant, Polycrystalline silicon plant, Petrochemical plant, valve, flange, vessel and so on. The sprial wound gasket are good at high temperture, high pressure and erosion resistance.   Products Features: 1. The material of Sprial Wound Gaskethas two parts, the metal part and the non-metal part.
2. The metal part: Carton Steel, 304, 304L, 316, 316L, Ti, Monel, Ni, Hastelloy alloy, Inconel
3. The non-metal part: Graphite, PTFE, Non-Asbestos, Asbestos 4.Make gaskets suitable for high pipeline pressure on flat or raised flange faces.
5.Temperatures from cryogenic up to 1000 °C  

Filler Material	Temperature	Pressure
Graphite	-240°c+550 °cin oxidizing media	300 bar in hot water, oil, etc
	-240°+800°c in non-oxidizing media	200 bar in vapor oil, gases, etc
