The concept of spiral wound gasket construction was originated by Flexitallic in 1912,
inaugurating the beginning of a new era in safe, effective sealing. And we are the main
supplier of spiral wound gasket in China. The primary purpose for this development
was the increasingly severe temperatures and pressures used by U.S. refinery operators
in the first half of the century. The necessity for a gasket to have the ability to recover
cannot be over emphasized. The effects of pressure and temperature fluctuations,
the temperature differential across the flange face, together with bolt stress relaxation
and creep, demand a gasket with adequate flexibility and recovery to maintain a seal
even under these varying service conditions. The Rilson Spiral Wound Gasket is the
precision engineered solution to such problems, meeting the most exacting conditions
of both temperature and pressure in flanged joints and similar assemblies and against
virtually every known corrosive and toxic media.
Gasket Identification
Gasket Selection
Style CGI - A Style CG gasket fitted with internal ring which gives an additional compression limiting stop and provides heat and corrosion barrier protecting gasket windings and preventing flange erosion. Suitable for use with flat face and raised face flanges. See note at bottom of page 8 for inner ring requirements.
Style CG - Utilizes an external ring which accurately centers gasket on flange face, provides additional radial strength to prevent gasket blow-out and acts as a compression stop. A general purpose gasket suitable for use with flat face and raised face flanges up to and inclusive of class 2500. See note at bottom of page 8 for inner ring requirements.
Style R - Basic construction type. Inner and outer diameters are reinforced with several plies of metal without filler to give greater stability and better compression and sealing characteristics. Suitable for tongue and groove or male and female or grooved to flat face flange assemblies.
Style RIR - Solid inner metal ring acts as a compression stop and fills the annular space between flange bore and the inside diameter of the gasket. Designed to prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion at flange faces. Suitable for male and female pipe flanges.
