E.S. a.3.1.fa Flexitallic Gaskets . 1 SCOPE; This soec:fication cavers spiral wound gaskets manufactured by the Flexitallic Gasket Company, Inc. .2 manufacture Flexitallic gasket3 are manufactured by spirally winding a preformed metal strip and a filler on the .0. of metal winding mandrels. Normal practice is to reinforce the inner and outer most diameters with several plies of metal strip without filler. For specific apolications gaskets may be furnished in a variety of configurations such as with inner and/or outer solid metal rings to facilitate positioning, prevent blow-out, prevent crushing, etc. .3 TEST REPORTS: Upon request, a copy of the manufacturer's or distributor's standard Certificate of Conformance shall be supplied with each shipment. .4 MATERIALS: Unless otherwise stated on the drawing, the following standard materials shall be supplied. .1 Metal Strjc: AI5I 304 stainless steel .2 Filler; "Flexite Super" .3 Inner */ar Outer Solid Metal Ring (when required): Low carbon steel .5 MECHANICAL PROPERTIES (TVPICAL FOR "FLEXITE SUPER" FILLER) ; Tensile Strength; 460 PSI (MD) Compression at 1000 PSI: 24*/. 400 PSI (CD) Recovery: 24*/, .6 HARDNESS: Not applicable. .7 TOLERANCES: Gasket Diameter Up to 10" 10" to 24" 24" to 60" Io2i. + /- 1/64" + /- 1/32" + /- 3/64" O.D. */- 1/32" /- 1/16" + /- 1/16" Thickness -.003, * .010 -.003, r .010 -.005, .010 IMO DELAVAL INC.
