Product Description
SpecificationsSpiral wound gaskets - RIR TypeDescriptionGinseal Spiral wound gaskets are composed of a steel (inner &.outer )rings and a spiral sealing strip with non-metallic winding ,and all material are alternative according to the chemical compatibility. Its function is depend on the V-formed metal spiral strip’s mechanical characteristics.Ginseal provides CGI type (with inner ring & outer ring), CG type (only with outer ring), R type (without inner & outer ring), RIR type (only with inner ring) and also in monel, inconel, alloy and other material. These gaskets are proved to be suitable in most applications, and allow lower clamping forces than solid gaskets, albeit with a higher cost.RIR Type Spiral Wound Gasket:Item no.: JSG - SW40SWG with only inner ring &.without outer ring, it’s suitable for male and female flange. 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 materialPackage &.
