Flange Bottom Bolt Torque Sequence - Meridian SMOOTHWALL BIN Owner's Manual

Owner's Manual: Smoothwall Bin

6.3.5 Flange Bottom Bolt Torque Sequence:

ALWAYS TIGHTEN THE NUT,
NOT THE BOLT!
Note:
Bolts should only be torqued if they
are fitted into clearance holes.
Apply Loctite® LB 8150, or equivalent, anti-
seize lubricant to the bolt threads. Then, use
a torque wrench to tighten the nuts to 55 ft-lb.
If the bolt head is torqued rather than the nut
then the torque value should be increased to
compensate for the additional friction.
The specified method of bolt tightening is
equally applicable to coated, galvanized and
ungalvanized bolts.
Torque the nuts or bolts in a "CRISS-CROSS",
then a "CIRCULAR" sequence using two
torquing passes as described below:
• Tighten all nuts by hand as far as possible.
• See Figures 26 to 29 for torque sequence.
• PASS 1: Torque the nuts to 55 ft-lb.
Torque in the correct sequence to a 100% of
the final torque value. Check that gasket is
getting compressed uniformly.
• PASS 2: Repeat torquing the nuts using the
final torque value in a "CIRCULAR" manner
until no further rotation of the nut is observed.
