1.) “R” for sizes 4" and 6" is .120"; for 8"-12" is .145"; for 14" and 16" is .165"; for 18"-24" is .185"; and for 30" and 36" is .215".
2.) 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".
3.) 30" and 36" sizes are not included in AWWA C606. For tolerances see AWWA C606.

Shouldered Joint Pipe

AMERICAN shouldered joints are furnished on fittings and on statically cast pipe as shown below. On centrifugally cast pipe the shouldered joint is furnished with a welded steel end ring fabricated as shown below right. Consult AMERICAN regarding specific requirements.

Wall thickness will vary according to service requirements and with method of casting – centrifugal or static. Consult AMERICAN for details.

Shouldered Joints with other dimensions can be furnished under certain circumstances. Consult AMERICAN for details.

Couplings for shouldered joints are not designed or manufactured by AMERICAN, but may be furnished on request. Consult with AMERICAN for recommendations.

Welded rings can be furnished on minimum pressure classes of ductile iron pipe. Maximum laying length is 19’6" and minimum laying length is 1’6" for all sizes. Check with AMERICAN if smaller sizes of shouldered end pipes are desired.
