Bolt torque calculation for flange with insulating kit (gasket)
Bolt torque calculation for flange with insulating kit (gasket)
(OP)
Please, can someone tell me the effect that insulating gasket kit (phenolic Type-D RJT, mylar bolt sleeves) will have on the torque calculation for a 16" ANSI RTJ Class 900 flange [studs 20 X (A193 Gr B7: 1-58"X 11-1/2")]. Recommended torque value for this scenario will be helpful.
