Wide application of spiral wound gaskets

Spiral wound gaskets are the most common metal gasket used in industrial equipment. Spiral wound gaskets that are correctly selected and installed can withstand high temperatures and pressures, thereby preventing leakage during their expected service life. Color plays an important role in spiral wound gaskets. The color of the outer ring and the color of the stripes along the ring are important indicators of the material inside the gasket.

For the worst conditions, spiral wound gaskets with additional inner rings are available. This protects the windings from contamination or product erosion through pipe joints. Spiral wound gaskets were developed in the early 20th century to meet the increasingly demanding conditions in refinery operations.

Spiral wound gaskets are made by winding alternating metal strips and filler materials on an inner ring made of special steel. Designed to easily balance any changes in temperature and pressure during the sealing process to ensure an excellent and safe seal.

Although the basic materials are carbon-rich, stainless steel, and flexible graphite; these materials can be changed according to various factors. The main factors that help determine the materials used include chemical compatibility, fluid concentration, corrosivity, operating temperature, and material cost.
