It works as an additional compression stop and prevents the inner buckling of the sealing element. This minimizes the risk of material creep through over-tightening. This standard is a purchase specification for metallic, flat, ring-shaped gaskets for use in circular, raised-face, flanged pipe joints as described in ANSI B16.5, API Standard 605, and MSS SP-44. Engineered Gasketing Technical Manual. In this article, you will learn about Spiral Wound Gasket. The inner metal ring of the CGI-style gasket constrains the sealing element on both internal and external diameters. The ISW3 Spiral Wound gasket is with outer metal ring. 0000008510 00000 n 0000003296 00000 n Thickness tolerance is 0.13 mm measured across the metallic portion of the gasket, not including the filler, which may protrude slightly beyond the metal. This specification is written as amendments and supplements to ASME B16.20:2012, which are covered in Part II of this MESC SPE. They are somewhat inexpensive, durable and in most cases readily available (pending metallurgical and filler requirements). Spiral wound gaskets can be used to seal fluid pressures up to 250 bar and from cryogenic temperatures up to elevated temperatures of 1000oC. However, PTFE is not suitable for use in high-temperature applications. Spiral wounds gaskets ( SWGs) are a great multi-purpose gasket used in piping systems throughout the world. These gaskets are fabricated from thin metal strips sandwiched between layers of non-metallic filler. 4. It is a general purpose Gasket suitable for use with flat face and raised face flanges.

SWG is a short form of Spiral Wound Gasket. When ordering it providing complete specifications is required: inside dimensions (AxB), width (b) and thickness (s) or a drawing. The color of the outside rim tells the material of the gaskets winding whereas the rim strip color tells about the gaskets filler material. Winding can be a V-type or W-type. By browsing this site, you agree to cookie use. Clean the bolts and lubricate them with a quality lubricant, such as an oil and graphite mixture. Two types of gaskets are covered: double-jacketed corrugated gaskets and spiral-wound gaskets. Product Description: The inner ring can be faced with graphite or PTFE as desired. Some of the common spiral wound gasket styles are: Style CG This type of spiral wound gasket is composed of a sealing element and an outer metal ring. Spiral wound gaskets are available for classes 150 to 2500. One material used in the sealing element is usually a metal and the other, referred to as a filler, which is a soft nonmetallic material, typically Teflon . 0000001953 00000 n The outer ring ensures optimum sealing performance by preventing over-compression. Place the gasket on the flange surface to be sealed. SUNWELL SEALS gasket factory covers an area of 10,000 square meters, has 115 workers specializing in gasket production, and has a monthly production capacity of 450,000 pieces. They are popular in the oil and gas, chemical, petrochemical, power, and food industries and prevents leak through flange joints. 0000262245 00000 n Suitable for high temperatures and pressures. 40 0 obj <>/Filter/FlateDecode/ID[<84884F9414B995499E6EBC3710EA9975>]/Index[32 23]/Info 31 0 R/Length 60/Prev 142201/Root 33 0 R/Size 55/Type/XRef/W[1 2 1]>>stream Bolt Torque Values - CANFLEX Spiral Wound RW THOMSON PERFORMANCE SEALING ASME B16.20 CANFLEX Spiral Wound RW Gaskets on ASME B16.47 Flanges - SERIES A Recommended Bolt Torque (ft-lbs.)
