Gasket series

Product details

A solid metal gasket that is softer than the mating flange material that is virtually ‘crushed’ into the flange face, creating a seal by filling imperfections and leak paths with gasket material. Under high sealing stress the gasket deforms but not the flange. They are used predominantly in the petrochemical industry (offshore oil platforms, refineries) due to the high service pressures required in their processes. Ring joint gaskets are machined to exact specifications and tight tolerances and come in a number of styles.

Product details

Spiral wound gaskets made by alternating a formed metal strip and a soft filler material to which form a gasket that produces a very effective seal when compressed between two flanges. The V-shaped windings of the metal strip acts as a spring, giving the gaskets greater resiliency under varying conditions.

The metal strip and filler materials of spiral wound gaskets can be changed, accommodating for different chemical compatibility requirements and fire safety is assured with selecting flexible graphite as the filler material.

Spiral wound gaskets may include a centering ring, an inner ring, or both. Spiral wound gaskets' outer centering ring ensures the gasket is centered within the flange and acts as a compression limiter. Spiral wound gasket inner rings provide additional radial strength, also reducing flange erosion while protecting the sealing element. The strength and resiliency of spiral wound gaskets make them the ideal choice in a variety of conditions and applications, and are used widely throughout refineries and chemical processing plants, also being very effective for power generation, pulp and paper, aerospace, and a variety of valve and specialty applications.

Spiral wound gaskets are manufactured to a number of specifications most notably being ASME B16.20 or EN 1514-2. Manufacture in accordance with the guidelines set forth in the ASME B16.20 or EN 1514-2 specifications plus many others to meet industry demands.
