Spiral Wound Sealing and Gaskets

Spiral Wound Gaskets - suitable for fluctuations in pressure and temperature

Spiral Wound Gaskets are made of a preformed thin metallic strip combined with a soft sealing composite material, wound together under pressure to energise the sealing element to act like a spring when compressed between two flange faces. The sealing element can be used stand-alone or in conjunction with inner and/or outer rings depending on the application. Spiral wounds are available in a full range of styles and materials and are manufactured in accordance with ASME B16.20 for use in all industry flanges, including ASME/ANSI B16.5, ASME B 16.47, Series A & B.

Designed for tongue and grove applications, the style S gasket is a stand-alone sealing element where the ID is reinforced with several layers of metal winding, filler material is then introduce to offer greater sealing ability and the gasket is finished with several more layers of metal to help insure stability.

Style SI - Sealing Element with Inner Ring

The SI configuration is the same as the S except that a solid inner ring is utilised to prevent over compression. This design is also helpful in turbulent applications which are prone to cause erosion of the flange faces.
