Restrained Joint Pipe

Grooved and Shouldered Joints

The AMERICAN grooved joint, furnished in sizes 4" to 36", and the AMERICAN shouldered joint, furnished in sizes 18" to 64", are fabricated joints most often used in plant piping installations.

These joints are sometimes alternatives to the flanged joint, and they are suitable for all specified applications, such as those found in treatment plants and pump stations.

Both joints meet all applicable requirements of AWWA C606.

Available in both flexible and rigid designs, grooved and shouldered joints offer quick assembly. If a field-grooving machine is available, the field adaptability of grooved pipe may be advantageous.

Pressure Classes

Pressure ratings for both grooved and shouldered joint pipe are determined by the couplings. For more information on pressure capabilities, please consult the manufacturer’s website at Victaulic.com.
