The CGI spiral wound is the new standard spiral wound gasket per ASME B16.20 and is required unless otherwise specified by the user. The CGI is a CG style spiral wound fitted with an internal ring which gives an additional compression limiting stop and prevents inward buckling ring. The inner rings are typically made from the same material as the windings, but can be produced in other alloys depending on service. The outer centering ring accurately centers the gasket on the flange face, provides radial strength, and acts as a compression limiter. The outer ring is typically made from painted carbon steel, but other corrosion resistant materials are available like stainless steels and other higher temperature alloys. The CGI is suitable for use with flat face and raised face flanges and specified for high pressuretemperature service or where corrosive or toxic media are present.
