Spiral Wound Gasket with Excellent Compresion Resilience Low Coefficient of Friction Highly Durable

Quality assurance graphite spiral wound gasket with inner ring and outer ring spw gasket     Spiral Wound Gaskets are winding by "V" shaped metallic strip and soft non-metallic filler.     According to the requestment, the gaskets can be within inner and outer rings for improving the gaskets handling, fitting and versatility.     Depend on its excellent compresion resilience, it's suitable for sealing spots where the alteration of temperature and pressure are frequenty.Basic Type:    Basic type gasket: inner and outer diameters are reinforced with several piles of metal without filler to give greater stability and better compression characteristics. Suitable for tongue and groove, male and famale or grooved to flat face flange essemblies.Inner Ring Type:     Solid inner metal ring acts as a compression stopper. To prevent accumulation of solids, reduce trubulent flow of process fluids and minimize erosion, damages of gasket between flange bore and the inside diameter, the annular space is filled up by solid inner metal ring;    Suitable for male and female pipe flanges.Outer Ring Type:    Solid outer accurately locates the gasket on the flange face to give the additional radial strength to prevent gasket blowout and acts as a compression limiter. In case of installing the outer ring, it is very easy to install the gasket to flange face because the end of outer ring will touch at bolts;Suitable for use with flat face and raised face flanges. For class 900 and above an internal ring is recommended.Inner & Outer Ring Type:    An inner ring and outer ring type gasket will give an additional compression limiting stopper for gasket inner and outer side. It will prevent the corrosions on flange face at annular space;Suitable for use with flat face and raised face flanges and specified for high pressure and temperature service, Class 900 and above or where corrosive or toxic media are present.Spiral Wound Gaskets Materials:Metal Winding & Inner RingFiller MaterialsOuter Ring  MaterialsAs StandardFlexible graphiteAs StandardSS304(L)PTFECarbon Steel MicaothersOthersCeramic304(L)Stainless SteelNon-asbestos316(L)309 317310 310317L 321321 347347 410Alloy 20 Alloy 20Monel 400 Monel 400Titanium 1,2,7 Titanium 1,2,7Nickel 200 Nickel 200Inconel 600,635 Inconel 600,635Incoloy 800,825 Incoloy 800,825Hastelloy B2 Hastelloy B2C276 C276Duplex 31803 Duplex 31803Copper  Inner ring: Carbon steel also abailable  Marking and Stamping:Spiral Wound Specifications Temperature Limit And Color CodingterialMin Temp ºCMax Temp ºCAbreviationColor Coding304L Stainless Steel-195650304Yellow316L Stainless Steel-100800316LGreen321L Stainless Steel-195870321Turquoise347L Stainless Steel-195870347BlueCarbon Steel-40500CSSilverAlloy 20185600A-20BlackHastelloy B2/B3-185700Hast BBrownHastelloy C276-185700Hast CBeigeIncoloy 800-100850InCo800N/AIncoloy 825-100850InCo825N/AInconel 600-1001000InCo600GoldInconel 625-1001000InCo625GoldInconel X750-1001000InCo750N/AMonel 400-200800Mon400OrangeNickel 200-320600NI200RedTitanium-3201090TIPurple*Color Coding following ASME B16-20MaterialMin Temp ºCMax Temp ºCAbreviationColor CodingGraphite-212550GraphGrey StripePTFE-240260PTFEWhite SripeMica-2121000MICALight Green*Stripe Coding following ASME B16-20 Q1:Are you a Manufacture Factory?A1:Yes,we are factory,we have our own production lines. Q2:Does your company accept customization?A2:We accept OEM service. Q3: Do you provide free samples?A3 : Yes, free samples are available, generlly speaking, the buyer shall bear all the delivery cost. Q4: I am interested in the products but I don't have experience?A4: Tell us your budget and target market and we will give you  professional advice of exact kinds and quantity. Q5:I have other questions.A5:Okay, you can contact us directly online or offline, and we will be patient to answer for you./* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
