Spiral wound gasket Aiflon spiral wound gasket (SWG) consists of a thin metallic strip and soft non-metallic filler that are simultaneously wound on a rotating mandrel. the metal hoop is pre-formed with a V or W shaped profile,which allows the gasket to act as a spring between the flanges. Further,the hoop provides the basic structural element for the gasket while the non-metal filler material seals small imperfections on the flange surfaces. depend on its excellent compression resilient, it¡¯s suitable for sealing spots where the alteration of temperature and pressure are frequent,such as pipes,valve,pumps etc.they are available in all standard the flanges of sizes,e.g.ANSI,API,DIN,JIS,JPI,BS etc.
