Introduction FIRST AND FOREMOST The concept of spiral wound gasket construction was originated by Flexitallic in 1912, inaugurating the beginning of a new era in safe, effective sealing. 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. Metal Strip Filler Material 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...

GASKET IDENTIFICATION GUIDE RING COLOR CODING For ease of identification, Flexitallic Spiral Wound Gaskets utilize a color coding system around the outside edge of the centering ring, thus permitting full identification of both the winding and filler materials. a solid color identification around the outside edge Light Green Stripe The gasket filler materials number of stripes placed at equal intervals around the centering ring.

GASKET SELECTION What style of gasket should I select? Style CG - Utilizes an external ring which accurately centers gasket on flange face, provides additional radial strength to pre- vent gasket blow-out and acts as a compression stop. A general purpose gasket suitable for use with flat face and raised face class 2500. Above class 600 an internal ring is recommended. 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...

SPECIAL GASKETS Gaskets of special design can be engineered and fabricated using the same basic fundamentals of Flexitallic Spiral Wound Gasket design and construction to cover a wide range of applications in installations for which there are no industry-wide standards. Special gaskets have been designed for valves, pumps, compressors, tur- bines, boilers, heat exchangers, etc. Consult with Flexitallic engi- neers as early in the design stage GOVERNMENT SPECIFICATIONS Flexitallic Spiral Wound Gaskets are available in accordance with Military Specifications MIL-G- latest revisions.
