General Notes Relating to AMERICAN Specials

The principal standards relating to AMERICAN Specials are ANSI/AWWA C110/A21.10, C151/A21.51, and C153/A21.53. These and other standards are referenced throughout this Section either by the full ANSI/AWWA designation or by only the AWWA numbering, such as AWWA C110.

In addition to the full complement of Mechanical Joint, Fastite®, Restrained Joint and Flanged fittings, AMERICAN furnishes many special fittings to meet special construction requirements. AMERICAN Specials include types and lengths of wall pipe, wall castings and fabrications, fittings with combinations of joints, and a number of other special fittings.

Many of the special fittings furnished by AMERICAN are included in this Section.

General Notes Relating to AMERICAN Specials 1. 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. 2. Pipes are manufactured of ductile iron, grade 60-42-10, (minimum tensile strength: 60,000 psi; minimum yield strength: 42,000 psi; minimum elongation: 10%) in accordance with AWWA C151. 3. Flange adaptors for AWWA C110/C115 Flange to ANSI/ASME B16.1 Class 250 Flange are manufactured of ASTM A36 steel. 4. Flanges and static-cast MJ bells can be tapped for studs when specified by the purchaser. Wall pipes with centrifugally cast MJ bells will, however, be provided instead with heavy-duty steel keylocking thread inserts to accept threaded studs. 5. All pressure ratings shown are AMERICAN's suggested standard and are for water service. 6. AMERICAN furnishes one fabricated thrust/water stop collar design with 360° fillet welds on both sides of the collar. This pipe collar can effectively and interchangeably be used for both thrust collar and water stop applications. 7. Unless otherwise noted, all cast-on flanges are per AWWA C110 or C153, and all threaded-on flanges are per AWWA C115. 8. All Mechanical Joints comply with AWWA C111. Threaded-on or otherwise fabricated MJ bells are per applicable portions of AWWA C115 and C153. Weights of MJ accessories are not included in weights of fittings with MJ outlets shown in tables, unless otherwise specified. 9. Weights of fittings can vary due to changes in foundry practice. 10.
