WARNING: It is extremely important to follow
a proper tightening sequence. If not followed,
the flanges can become cocked and a leak
will result. When tightening flanges with
spiral wound gaskets, if cocking occurs, the
result can be deformation and non-repairable
damage to the gaskets in addition to a
resultant leak. Any gasket leak can result in
potential injury to adjacent personnel.
