Notes
Reference should always be made to the I-100
Victaulic® Field Installation Handbook for the
product you are installing
www.victaulic.com
All References are based Victaulic “Duplex –
grooved couplings 17.20”.
1)
At least 2 flexible couplings must be used to compensate radial misalignment. Angular deflection of each
joint must not exceed Maximum angle from centerline. Se example reference “Victaulic – Design Data 26.01
page 3.
2)
The grooved piping method will not allow both maximum linear movement and maximum angular move
ment simultaneously at the same joint.
3)
End Loads are total, from all internal and external loads, based on duplex stainless steel pipe.
Pipe support
Flexible coupling Styles 77 and others standard
grooved-type couplings allow angular, linear and
rotational movement at each joint, to accommo-
date expansion, contraction, settling,
vibration, noise and other piping movement.
This must be considered when determinate
hanger and support bracing. See Reference
Victaulic – Design Data 26.01.
