Spiral Wound Gasket(SWG) 1) Definition: A kind of semi-metal flat gasket made by winding metal strap and non-metal strap in helix direction. 2)Characteristics: A spiral wound gasket (SWG)able to compress and seal under various loads and provide sealing capabilities. The gasket generally includes a spiral wound portion and an outer guide ring to limit the compression of the gasket. The spiral winding is formed of interdisposed windings of a metal and an elastomer sealant. The metal winding has a non-planar cross-section to inhibit buckling under compression. The gasket is dimensioned such that the elastomer sealant winding has a width greater than the width of the metal winding which has a width greater than the thickness of the guide ring. In this manner, the sealant is compressed before compression of the metal winding which can be compressed until the outer guide ring is encountered 3) Application: Widely applied in static sealing parts of technological pipelines, and the equipments of many industries, such as petroleum refining, petroleum chemistry, chemistry, thermal electricity, nuclear energy, spaceflight, spinning, medicine and other industries 4)Implemented standard: ASMI, BS, JIS, DIN 5)Material for Hoop: 0Crl 3, **4SS, **4LSS, **6SS, **6LSS, CS, **6Tiss, Inconel **0 6)Filler : Graphite, PTFE, Asbestos, Non-Asbestos 7)Type: Basic type(R): with outer ring ( CG ) with inner ring (RIR) with inner&outer ring (CGI)
