Flexible Couplings in straight runs should be supported as close to the coupling as possible, or within the distance of 1/6 the span, and evenly spaced.
Flexible Couplings provide either axial or longitudinal movement. The available movement for roll-grooved joints is 1/2 of cut-groove dimensions per ANSI/AWWA C606-06.
When pre-setting 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.
Coating options: Epoxy, Paint, Dacromet, Hot-Dip Galvanized.
