Less than half the studs3-Multiple metal windings & fillers availableThe concept of spiral wound gasket construction was originated by Flexitallic in 1912,inaugurating the beginning of a new era in safe, effective sealing. And we are the mainsupplier of spiral wound gasket in China. The primary purpose for this developmentwas the increasingly severe temperatures and pressures used by U.S. refinery operatorsin the first half of the century. The necessity for a gasket to have the ability to recovercannot be over emphasized. The effects of pressure and temperature fluctuations,the temperature differential across the flange face, together with bolt stress relaxationand creep, demand a gasket with adequate flexibility and recovery to maintain a sealeven under these varying service conditions. The Rilson Spiral Wound Gasket is theprecision engineered solution to such problems, meeting the most exacting conditionsof both temperature and pressure in flanged joints and similar assemblies and againstvirtually every known corrosive and toxic media.Gasket IdentificationGasket SelectionStyle CGI - 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 and raised face flanges. See note at bottom of page 8 for inner ring requirements.Style CG - Utilizes an external ring which accurately centers 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 up to and inclusive of class 2500. See note at bottom of page 8 for inner ring requirements.Style R - Basic construction type. Inner and outer diameters are reinforced with several plies of metal without filler to give greater stability and better compression and sealing characteristics. Suitable for tongue and groove or male and female or grooved to flat face flange assemblies.Style RIR - Solid inner metal ring acts as a compression stop and fills the annular space between flange bore and the inside diameter of the gasket. Designed to prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion at flange faces. Suitable for male and female pipe flanges.why choose us?1)world class gasket2)standard/no standard gasket3)genuine products with excellent quality4)after sales service and technical assistance:Rilson provide after sales service as the customer's requirement and needs.5)quick delivery:Rilson provides just-in-time delivery with its steamlined supply chain.6)less cost of purchase:Rilson is a direct importer and agent of manufacturers around global, so there are no intermediary costs involved.If you are interested in our products, please contact me in Ali and in Emailand I will reply to you as soon as possible.My target of service is to satisfy your requirements.Your Success is my busines.StyleStructureHoop materialFillerInner & outer ring materialSWGWith inner & outer rings304(L),316(L),321,317(L), 31803,Monel,Ti,Ni,INC, Hast.
