Spiral wound gasket. These gaskets, also known as spiral-wound gaskets, can be used with both flat-surface and raised-surfaces pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection. A spiral wound gasket consists of alternating layers of metal winding (usually stainless steel) and filler material (such as flexible graphite or polytetrafluoroethylene [PTFE]) wound in a spiral shape. S. It consists of a V-shaped metal strip and a softer filler material that is wound in a spiral fashion to create a resilient sealing surface. They are popular in the oil and gas, chemical, petrochemical, power, and food industries and prevents leak through flange joints. A properly selected and installed spiral wound gasket can withstand high temperatures and pressures, preventing leaks throughout their intended lifespan. Learn about retaining rings, filler materials, compression specs, and ASME B16. Spiral wound gaskets are a type of industrial gasket made by spirally winding a metal strip together with a non-metallic sealing material. This combination makes them ideal for highly demanding environments, such as steam systems, heat exchangers, reactors, valves, or industrial process flanges.
