Duplex H Type Spiral Wound Gasket For Heat Exchanger Or Customized Type

SpecificationsSpiral wound gaskets - H TypeDescriptionGinseal heat exchanger spiral wound gaskets are created for heat exchangers, It’s same with common spiral wound gaskets in structural type except that barrettes(bar) are required. Always the barrettes are always double jacketed type or kammprofile type. . H Type Spiral Wound Gasket:Item no.: JSG - SWHSpiral Wound Gasket for heat exchanger.For example: SS304/FG with 1 bar of Double Jacketed.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
