Metal Spiral Wound Gasket
Metal spiral wound gasket is manufactured using standard high – quality metal materials such as SUS304, SUS316 (“V” shape or “W” shape), TA, C276, etc., wound with filler materials like graphite, non – asbestos, and polytetrafluoroethylene. These materials are spirally wound in an overlapping manner, and the metal windings are fixed by spot welding at the start and end. They are suitable for high – temperature and high – pressure gases, oils, solvents, and thermal media oils.
