Specification of Spiral Wound Gaskets
Spiral Wound Gaskets Basic Types:
features:
Basic type spiral wound gaskets consist of a thin metal strip and soft non-metallic filler are simultaneously wound on a rotating mandrel. Pre-shaped metal hoop with a V or W shaped profile which allows the gasket to act as a spring between the flanges. Furthermore, the circle provides the basic structural element for the gasket while non-metallic filler material seals small imperfections in the surface of the flange. Depending on the excellent compression resilient, it is suitable for sealing where changes in temperature and pressure are frequent, such as pipes, valves, pumps etc. They are available in all standard flange sizes, for example, ANSI, API, DIN, JIS, JPI, BS etc
Spiral Wound Gasket With Outer Ring:
features:
Solid outer ring spiral wound gaskets consist of a metal guide ring and sealing elements. External ring accurately to the flange face gasket Center: provides additional radial strength to prevent gasket explosions and acts as a compression stop. This profile is typically used in raised and flat faced flanged. The outer ring is often made of carbon steel (painted or zinc plated to prevent corrosion) but can be made of alloys for higher temperatures and more severe media applications.
Spiral Wound Gasket With Inner Ring:
features:
Solid in the spiral wound gasket ring has an inner ring. Solid metal ring to act as a stopper compression and fill the annular space between flange bore and the inside diameter. Designed to prevent the accumulation of solids, reduce turbulent flow of process fluids and minimize erosion of flange faces. It is suitable for male and female pipe flanges.
Spiral Wound Gasket With Inner and Outer Ring:
features:
spiral wound gasket has an outer ring and the inner ring of solid .However been incorporated to improve performance gaskets and external guide ring accurately Center flange gasket on the face. Ring sections are added to prevent possible gasket burst into the pipes during installation, to protect the sealing element from the extreme temperatures and the media, filling the void between the flanges to prevent erosion flange, and to reduce the possibility of failure. The inner ring is usually made of the same alloy with winding. DIN 2699 standards (Germany) set in the ring in all of spiral wound gaskets. the inner ring is required for gaskets with PTFE filler in accordance with ASME B16.20 standards, and are considered important for graphite filler. This profile is typically used in raised and flat face flanges. The external ring provides additional radial strength to prevent gasket explosions and acts as a compression stop. This profile is typically used in raised and flat faced flanged. The outer ring is often made of carbon steel (painted or zinc plated to prevent corrosion) but can be made of alloys for higher temperatures and more severe media applications.
