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.

Metal Strip Filler Material The necessity for a gasket to have the ability to recover cannot be over emphasized. 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. Light Green Stripe The gasket filler materials number of stripes placed at equal intervals around the centering ring. Non-sintered PTFE high-temperature, sealing material is comprised of chemically exfoliat- ed and thermally exfoliated vermi- This revolutionary new product simulates the structure of exfoliat- ed graphite but with one notable exception gaskets made with Thermiculite maintain their integri- ty, even at extreme temperatures. 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. 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. 1500 are identical within their respective nominal pipe sizes, therefore inventories need not be duplicated.

S FLANGES See Table 4 for small diameter screwed and slip-on flanges. CGI SPIRAL WOUND GASKETS This table shows the maximum bore of flanges for which the Spiral Wound gasket dimensions shown are recommended considering the tolerances involved, possible eccentric installation, and the possibility that the gasket may extend into the assembled flange bore.
