Available in a full range of styles and materials, our spiral-wound gaskets are manufactured in accordance with ASME B 16.20 for use in all industry flanges, including ASME B16.5 and ASME B 16.47, Series A&B. Leader GT assures strict adherence to these specifications as routine inspection procedures are applied throughout the manufacturing process. In addition, we maintain traceability of all materials used in our gasket construction to provide material certifications as required. Spiral wound gasket (SWG) consists of a thin metal hoop and nonmetal filler material that is simultaneously wound. The metal hoop is pre-formed in V or W-shaped profile, which allows the gasket to act as a spring between the flanges. The hoop also provides the basic structural element for the gasket while the nonmetal filler material seals the flange surfaces that are with small imperfections. It has been widely applied in the fields of petrochemical, mechanical manufactory, power station, metallurgy etc.
