GASKETS - Spiral Wound Gasket - SW-600 Ranges Spiral wound gasket is formed of V-shaped metallic strip and soft non-metallic filler by means of piled, spiral wound gasket and connected its end and beginning by dot welded. Depend on its excellent compression resilience, it is suitable for sealing sports where the alteration of temperature and pressure are frequent. It can be used as the static sealing element of pipe, valve, pump, thermal exchange, condensing tower, plain hole and man hole of flange, etc. It has been widely applied in the fields of petrochemical, mechanical factory, power station, metallurgy, shipbuilding, medical and pharmaceutical unclear power station and navigation, etc. Note: Please offer the detailed drawing, while the gasket is used in thermal exchanger with some ribs. Types of Spiral Wound Gaskets: SUNWELL SW600-R Basic Style Spiral Wound Gasket Basic construction style, inner and outer diameters are reinforced with several plies of metal without filler to give greater stability and better compression characteristics. Suitable for tongue and groove or male and female or grooved to flat face flange assemblies. SUNWELL SW600-RIR Spiral Wound Gasket with Inner Ring Solid inner metal ring acts as a compression stop and fills the annular space between flange bore and the inside diameter. Designed to prevent accumulation of solids, reduce turbulent flow of process fluids and minimise erosion of flange faces. Suitable for male and female flanges.

It’s an external ring which accurately center gasket on flange face, provides additional radial strength to prevent gasket blow-out and acts as a compression stop. A general purpose gasket suitable for use with flat face and raised face flanges, class 900 and above an internal ring is recommended. SUNWELL SW600-CGI Spiral Wound Gasket with Inner & Outer Rings A style CG gasket fitted with internal ring which gives an additional compression limiting stop and provides heat and corrosion barrier protecting gasket windings and preventing flange erosion. Suitable for use with flat face flanges and...
