This gasket system also has an inner as well as outer support ring in addition to the wound spiral. Spiral wound gaskets are to be constructed as alternate plies of preformed metal windings (hoop) and plain fillers that are spirally wound when compressed betweentwo flanges. The outer guide ring serves to locate the spiral element centrally on the flange faces and prevent blow-out. Prevents Damage to The Gaskets Bore And Inner Windings - Acts As A Heat And Corrosion Barrier - Application As General And Critical Duties. This gasket has the best sealing characteristics combined with the highest safety for flanged joints with flat face and raised face. However, these gaskets may be supplied without inner rings per customer request. Ring joint: Iron or soft steel Monel or 4%-6% chrome Stainless steels & Nickel based alloys: 5. OGF-Spiral Wound Styles: STYLE - G Basic construction 'G' without inner and outer ring. The design is based on an existing concept which has proven its excellent properties over many years. Carbon steel is used to manufacture spiral wound gaskets, generally on the outer centering ring. With x Without Inner Ring 0 50 100 150 200 250 300 350 400 450 500 e (V) Inner Ring = better result SWG SWG-IR 8. Color cord as ASME B 16. The 913M is the standard spiral wound gasket with an inner ring. This gasket has the best sealing characteristics combined with the highest safety for flanged joints with flat face and raised face. CGI Gaskets by Flexitallic are style CG gaskets fitted with an internal ring. SPW gasket with graphite or PTFE filler, without inner and outer ring The gasket comprises a spirally-wound beaded metal band ( Standard: 316L; other materials on requirement ) in which a non-metallic band ( graphite or PTFE ) overlaying on both sides is inserted between the individual spirals of the metal band. Types: MIP Spiral Wound gaskets are manufactured with inner and outer ring, with Inner ring only, with outer ring only and without rings as per buyer's requirements. Spiral wound gaskets are available for classes 150 to 2500. The gasket is suitable for flange, valve, pump, heat exchange etc. The outer ring mainly centrers the gasket between flanges, while the inner ring provides strenghth and also reduces internal turbulences and protects the sealing element. Spiral Wound Gasket per ASME B16. ATOM's automated cutting systems cut with extreme precision and repeat ability, to within +/- 0. Description KXT620 Spiral wound gasket for heat exchangers are designed for heat exchangers, it can be with or without inner and outer rings. Enhances compression of the graphite filler and spiral elasticity. Ningbo Kaxite Sealing Materials Co. Specialist markets include refining petrochemicals, power. Spiral wound gaskets can be strengthened by an centering ring and/or inner ring. The basic principle of the spiral gasket consists of alternating layers of V-shaped metal coils and soft, non-metallic filler material. 5, BS1560, ASME B 16. Based on published papers, buckling problems seem to be related to a number of variables including: pipe size, pressure, temperature, and gasket filler material.
