ASME B16.20 Metal Gasket Material available: CS/304/304L/316/316L/321/347... all steel family
Basic Type
Basic construction type, inner and outer diameters are reinforced with several piles of metal without filler to give greater stability and better compression characteristics. - Suitable for tongue and groove, male and female or grooved to flat face flange assemblies.
Inner Ring Type
Solid inner metal ring acts as a compression stopper. To prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion, damages of gasket between flange bore and the inside diameter, the annular space is filled up by solid inner metal ring. - Suitable for male and female pipe flanges.
Outer Ring TypeSolid outer ring accurately locates the gasket on the flange face to give the additional radial strength to prevent the gasket blowout and acts as a compression limiter. In case of installing the outer ring, it is very easy to install the gasket to flange face because the end of outer ring will touch at bolts - Suitable for use with flat face and raised face flanges. For class 900 and above an internal ring is recommended.

A spiral wound graphite gasket is a type of industrial gasket that can be used in renewable energy applications, such as wind power and solar power.
The gasket consists of a metal ring with a spiral wound sealing element made from graphite and a filler material, such as stainless steel or Inconel. The graphite provides excellent resistance to high temperatures and corrosive chemicals, making it ideal for use in renewable energy applications that involve high temperatures and harsh environments.
In wind power applications, spiral wound graphite gaskets can be used to provide a reliable and tight seal in turbines, gearboxes, and other components that are exposed to high winds and harsh environmental conditions. The gaskets can also be used in solar power applications to provide a reliable seal in solar panels and other components that are exposed to high temperatures and UV radiation.
The spiral wound design of the gasket provides a uniform load distribution, which helps to prevent leaks and ensures a tight and reliable seal between the flanges. The gasket is designed to be used with flanges that meet the ASME B16.5 or B16.47 standards, ensuring compatibility with a wide range of engineering applications.
The spiral wound graphite gasket is a reliable and versatile sealing solution that can be used in renewable energy applications to provide excellent resistance to high temperatures and corrosive chemicals, helping to ensure the efficient and reliable operation of renewable energy systems.
