Sprial Wound Gasket Spiral wounds gaskets have proven themselves to be the most reliable sealing element for use in variety of conditions and applications. They are made by winding alternating strips of metal and soft filler material. A 'V' or 'W' shaped crown centered in the metal strip acts as a spring, giving gaskets greater resiliency under varying conditions. Filler and winding material can be changed to accommodate different chemical compatibility requirements. Widely used throughout refineries and chemical processing plants, spiral wound gaskets are also effective for power generation, aerospace, and a variety of valve and specialty applications. Spiral wound gaskets are manufactured as per ASME/ANSI B16.5 (API 601), ASME B16.47 Series A (MSS-SP44), ASMEB16.47 Series B (API 605), BS 1560, BS 4504, BS 10, DIN/EN 1092, JIS Flanges and French NF standard. Size and shape as per prevailing international standards or customer need can be produced Technical Specifications
