Flanges are manufactured from ASTM A36 steel. Holes are drilled and tapped to mate with AWWA C110/C115 flanges on one side and ANSI/ASME B16.1 Class 250 flanges on the opposite, or other side. Holes are equally spaced straddling the centerline.
Fittings are manufactured of ductile iron, grade 70-50-05 (minimum tensile strength: 70,000 psi; minimum yield strength: 50,000 psi; minimum elongation: 5%) in accordance with AWWA C110 or C153.
Flange adaptors for AWWA C110/C115 flange to ANSI/ASME B16.1 class 250 flange are manufactured of ASTM A36 steel.
Flanges and static-cast mechanical joint bells can be tapped for studs when specified by the purchaser.
Unless otherwise noted, all cast-on flanges are per AWWA C110 or C153, and all threaded-on flanges are per AWWA C115.
Weights of fittings can vary due to changes in foundry practice.
