1. Tables are to be used only as a general guide. 2. Tables should not be considered to contain absolute values due to the large number of uncontrollable variables involved with bolted joints. 3. If there is doubt as to the proper torque value to use, it recommended that the maximum value be used. 4. All bolt torque values are based upon the use of new nuts and new bolts of proper design, acceptable quality and approved materials of construction as well as metallurgy. 5. The flanges are assumed to be in good condition and in compliance with ASME B16.5 specifications. Special attention should be given to seating surface finish and flatness. 6. Only torque wrenches that have been calibrated should be used. 7. Refer to Drawing No. 467972 for the flange bolting procedure to be used. 8. No provisions have been made in these tables to account for vibration effects on the bolts. 9. Spiral wound gaskets are to be supplied with both outer (centering) and inner rings.
