Advantages Corrosion inhibitor for treatment of potable water systems When added to supply water, inhibits corrosion by forming a stable, evenly distributed protective film on the inside of distribution piping and metal surfaces. Provides the advantages of a zinc phosphate formulation but Components are selected for long-term reliability, so the valves will provide service life equaling or exceeding that of the pipeline.

Steel flanges have been used with steel pipe in the water- works field since the first riveted, steel water-supply lines were installed with flanges attached by riveting.

Steel-plate ring flanges and rolled-angle flanges, to match the drilling of existing cast valves and cast fittings, were also used extensively. The greatly increased usage of steel pipe for waterworks service during the s made standardization of flanges desirable. The ratings were far higher than those ordi- narily needed for water service. The generally accepted rules for the design of bolted, flanged connections embraced all fields of usage and a wide range of pressure and temperature applica- tions.

In waterworks practice it is not necessary, within the scope of this standard, to deal with temperatures greater than the atmospheric range, and it is possible to restrict consideration to joints with softer gaskets and to flanges that are flat faced. The designs were prepared in conformity with these limitations. AWWA, 36 9 September The committee decided to follow this practice for sizes 6 in. The design of flanges for waterworks service, with the results of the preceding report, was published in Journal AWWA in October , pp.

Through In. The next edition, designated AWWA C with the same title, was published in and revised the maxi- mum test pressure to percent of the flange rating, added segmentation of flanges, blind flanges, class E ring flanges, class F ring and hub flanges, and toler- ances for flange draft or layback.
