Polг Tico Tгўctica De Repuesto Tabla De Torque Para Esparragos Bosquejo Spiral wound gasket cgi. notes: torque values are in ft. lbs., and assume alloy steel bolts (a193 b7 w 2h nuts) with oil graphite lubrication. (nut factors used on these charts are within .15 to .19) we do not generally recommend a bolt stress above 60,000 psi. Spiral wound gasket cgi series a. notes: torque values are in ft. lbs., and assume alloy steel bolts (a193 b7 w 2h nuts) with oil graphite lubrication. (nut factors used on these charts are within .15 to .19) flexitallic does not generally recommend a bolt stress above 60,000 psi torque values limit minimum and maximum gasket seating. Spiral wound gasket cgi. notes: torque values are in ft. lbs., and assume alloy steel bolts (a193 b7 w 2h nuts) with oil graphite lubrication. flexitallic does not generally recommend a bolt stress above 60,000 psi torque values limit minimum and maximum gasket seating stresses based upon pressure class and certain operating conditions.(i.e. Torque values are in ft. lbs., and assume alloy steel bolts (a193 b7 w 2h nuts) with oil graphite lubrication. (nut factors used on these charts are within .15 to .19) flexitallic does not generally recommend a bolt stress above 60,000 psi.
Astm A193 B7 B7m Stud Bolt M32 Hex Head Bolts Nut Spiral wound gasket cgi. notes: torque values are in ft. lbs., and assume alloy steel bolts (a193 b7 w 2h nuts) with oil graphite lubrication. flexitallic does not generally recommend a bolt stress above 60,000 psi torque values limit minimum and maximum gasket seating stresses based upon pressure class and certain operating conditions.(i.e. Torque values are in ft. lbs., and assume alloy steel bolts (a193 b7 w 2h nuts) with oil graphite lubrication. (nut factors used on these charts are within .15 to .19) flexitallic does not generally recommend a bolt stress above 60,000 psi. Suggested torque values for use with teadit spiral wound 913m (with inner & outer rings) standard asme b16.5 raised face pipe flanges for use with astm a193 b7 bolting or equal yield strength bolt material. gasket to be per asme b16.20 and used with appropriate flange bore size per the 16.20 tables. Place the bolts into the bolt holes. finger tighten the nuts. follow the bolting sequence in the diagrams above. during the initial tightening sequence, do not tighten any bolts more than 30% of the recommended bolt stress. doing so will cause cocking of the flange and the gasket will be crushed. upon reaching the recommended torque.
