Flanges: Man hours are for labor attaching the flange perpendicular to the centerline of a section of straight pipe or
to a straight section of pipe on the end of a bend.
Pipe Thickness: Man hours are for any wall thickness of pipe used with listed flanges.
Weld Fittings or Bends: For attaching flanges to weld fittings or bends with no straight tangents or on a straight
section of pipe, but other than perpendicular to the centerline, add 25% to the above man hours.
Refacing: For flanges requiring refacing after welding increase above man hours 50'7r.
