Important: Shown are
the bolt tightening sequences for typical circular
flanges.
Do not fully tighten the bolts the first
time around as this can tilt the flange out of parallel.
The first time around tighten to approximately 1/2 of the
final torque, then
repeat the sequence, tightening to the suggested torque
limit.
