  1. Rigid couplings used in straight runs should be supported similar to welded or flanged piping. Refer to: ANSI B31.1, ANSI B31.9, NFPA 13.
  2. Rigid couplings do not provide longitudinal movement. However, a gap exists between pipe ends and should be considered when calculating axial displacement.
  3. Rigid couplings are recommended in areas of concentrated weight and where flexibility is not desired, to hold plumb and pitch.
  4. Where large concentrations of weight occur, such as in mechanical rooms and when installing valves, rigid couplings are highly recommended.
  5. When presetting power nut-drivers, the following torque should not be exceeded. Excessive tightening of the nuts could result in joint failure. (Values Lbs-Ft.) 3/8″=50-59; 1/2″=81-92; 5/8″=147-190; 3/4″=177-179; 7/8″=202=221.
  6. Coating options: Epoxy, Paint, Dacromet, Hot-Dip Galvanized.
