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.

1.) Minimum nominal wall thickness of centrifugally cast ductile iron pipe furnished with grooved joint. Thicknesses above correspond to special thickness class 53 for 4"-16" diameter, and special thickness classes 54 and 55 for diameters 18" and 20", respectively, and special thickness class 56 for diameters 24"-36".
2.) Maximum length for 4" size is 17’6"; for 6"-24" sizes is 20’0"; and for 30"-36" sizes is 19’6". Shorter lengths than the maximum lengths can, of course, be furnished – consult AMERICAN.
3.) 30" and 36" sizes are not included in AWWA C606. For tolerances see AWWA C606.
