SpecificationsSpiral wound gaskets – S TypeDescriptionGinseal Spiral wound gaskets are made of V-formed metallic strip and flat filler material. V-formed stainless strip works as spring providing structural support while the filler works as the sealing element. According to different service environment and different flanges, spiral wound gaskets are always supplied in different materials and types. Ginseal provides many types spiral wound gaskets, and also can supply according to customers’ requirement.S Type Spiral Wound Gasket:Item no.: JSG - SWCThe gaskets are manufactured according to customers’ drawing. Material for rings:Low Carbon Steel, SS304, 304L, SS316, SS316L, SS321, SS347, SS 410, Aluminium , Copper, Brass, Nickel 200, Monel 400, Inconel 600/625/800, Hastelloy B2, Titanium (see more information in our products catalogue)How to choose FillerThe important part is the sealing element (also called filler) made up of V-formed SS strip and non- metallic filling tape, the material can be changed according to different chemical compatibility requirements.Graphite filling strip is good to be used in high temperature environment,PTFE filling strip is for acids and other corrosive mediumsNon-asbestos’ use is increased when the health problems with asbestos became known. But it’s only recommended for low temperature less severe applications due to the rubber content.Ceramic is in extremely high temperature applications. The filler is not so common as it cannot achieve the same leak tightness as graphiteMarking (standard):Marking on outer ring:- Manufacturer- Nominal Size - Pressure Range- Winding material + Filler Material- Manufactured to (standard)For example: GINSEAL 2"150# SS304/SS304+F.G./CS ASME B16.20SpecificationsWe deliver according to the following standards: ASME B16.20, ASME B16.47 Series A & Series B, ANSI B16.5, BS1560, BS EN1092, DIN, JIS, etc.How to order1 -- Nominal pipe size or specific gasket dimensions2 -- Pressure rating3 -- winding and filler materials4 -- centering / outer ring or inner ring materialFurther materials available upon request
