A Spiral Wound Gasket is a type of metal gasket designed for sealing flange connections under high pressure and temperature conditions. It is the most widely used metal gasket in industrial applications with a broad range of pressure and temperature variations. These gaskets are constructed from a metal core in a spiral shape, combined with a filler layer, such as graphite, heat-resistant fibers, or a blend of both. The gaskets are made from thin metal sheets in a V-shape (strips), with a non-metallic filler wound spirally (both sides welded).
Types of Spiral Wound Gaskets:
- Spiral Wound Gasket Element only
- Spiral Wound Gasket with Inner Ring
- Spiral Wound Gasket with Outer Ring
The color coding for the outer edge, inner ring material, and the metal winding indicates specific materials used, such as:
- Blue: Stainless Steel Grade 347
- Orange: Monel
- Purple: Titanium
- Black: Alloy 20
- Silver: Carbon Steel
- Yellow: Stainless Steel Grade 304/316
- Red: Nickel
- Turquoise: Stainless Steel Grade 321
