Notes:

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. 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.

4. Washers are be used under the head of each nut and the lubricant is to be used on the nuts, bolts and washers.

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.
