2.4.4 Torque Specifications
It is recommended that the bolts and nuts be lubricated and tightened using a torque wrench. The
bolts and nuts should be tightened to approximately 50% of the torque value during the first pass, to
approximately 80% during the second pass and to the full torque during the third pass. The maximum
torque rate values shown in TABLES 2-1 and 2-2 must not be exceeded.
For liner materials other than those shown in the tables, the flange bolts should be tightened
sufficiently to stop any leaks but should not exceed the values shown in the tables.
