4 The color of the outside edge of the centering ring identifies both the winding and filler materials. The metallic winding filler materials are designated by color stripes at equal intervals on the outside edge of the centering ring. The Flexitallic color code meets the industry standard for metal and filler materials which has been adopted by ASME and the Metallic GASKET division of the Fluid Sealing RingSolid Green = 316 LGrey = FlexicarbSPIRAL WOUND GASKET INDENTIFICATION6 GASKET REFERENCE GUIDE 13 304SS 316L SS 317L 321SS 347 SSNo Color 310 SSNo Color 304 LSSNo Color 309 SSNo Color 430SS Alloy 20 Titanium Inconel 600/625 Incoloy 800/825No Color Inconel X750 Hastelloy C276 Hastelloy B2 Nickel 200No Color Zirconium Carbon Steel MonelNon-metallic Filler Materials Metallic Winding Materials PTFE Flexicarb Flexite Super Ceramic Thermiculite 835 SPIRAL WOUND GASKET INDENTIFICATION7 GASKET

Torque the bolts at 30% of the final loading using the appropriate bolt 60% of final 100% of final 100% of final torque using a clockwise pattern. 846273518-BoltsBOLTING RECOMMENDATIONS11 GASKET REFERENCE GUIDE 23846273518-Bolts84106211739511212-Bolts 8124146102157113135911616-BoltsGASKET INSTALLATION, TORQUE SEQUENCE12 GASKET REFERENCE GUIDE 25816410186142111971539175131122020-Bolt s201242214618102231571911321135179124168 24-BoltsGASKET INSTALLATION, TORQUE SEQUENCE13 GASKET REFERENCE GUIDE 2711792552113293191127723153121810266221 4304201228824163232-Bolts123417182033369 1012282726254241876521222324373839401314 19113534444329161532313044-BoltsGASKET INSTALLATION.

This will not damage the GASKET or affect the sealing performance and the ring is provided as a compression limiting optimum performance Flexitallic Spiral Wound gaskets should be compressed to these GASKET THICKNESSRECOMMENDED COMPRESSED mm ( in) mm ( in) mm ( in) mm ( in) mm ( in) mm ( in) mm ( in) mm ( in) mm ( in) mm ( in) mm ( in) mm ( in)REQUIRED GASKET COMPRESSION16 GASKET REFERENCE GUIDE 33 Torque Data Technical NotesTorque Values are in , and assume Alloy Steel Bolts (A193 B7 w/ 2H Nuts) with oil/graphite lubrication.

8 (Nut factors used on these charts are within .15 to .19) Flexitallic does not generally recommend a bolt stress above 60,000 PSIT orque values limit minimum and maximum GASKET seating stresses based upon pressure class and certain operating conditions.( : maximum pressure ratings for given pressure class,not hydrotest pressure). Extreme operating conditions such as high temperature may reduce bolt yield strength. Caution should be used in these applications. The following torque values are for general use only.
