40 <br />(UGCO2625.FMT)aa <br />P' <br />SECTION 02625 <br />WATER MAINS <br />DUCTILE IRON PIPE AND FITTINGS <br />1.01 SCONE <br />This section covers cast ductile iron pipe and cast <br />ductile iron fittings for water mains. <br />1.02 GENERAL <br />A. Ductile iron pipe shall be allowed for use as water <br />pipe where compatible with the specific conditions of <br />the project. The use of material other than ductile <br />iron may be required by IRCDUS during construction <br />permit review, or by IRCDUS field personnel, if it is <br />determined that ductile iron pipe is unsuitable for the <br />particular application. <br />E. All ductile iron pipe shall be manufactured in <br />accordance with AWWA Specification C-151 and shall be <br />class 50 minimum. All ductile iron pipe crossing under <br />roadways shall be Pressure Class 350 minimum. <br />C. Unless specifically indicated otherwise, restrained <br />joint underground piping shall be manufactured <br />restrained bell and spigot and aboveground piping shall <br />be flanged. <br />D. Cutting of ductile iron pipe shall be by sawing only. <br />1.03 PIPE <br />Ductile iron pipe shall be bell and spigot cast in <br />accordance with AWWA Specification 0151 (ANSI A21.51- <br />86), or latest revision. Cast ductile iron shall have <br />a minimum tensile strength of 60,000 psi, with a <br />minimum yield strength of 42,000 psi. Pipe wall <br />thickness shall be computed in accordance with AWWA <br />Specification 0150 (ANSI A21.50-81), or latest <br />revision, using the physical characteristics cited <br />above, with a minimum working pressure of 150 psi and a <br />Laying Condition "Type 2." Unless otherwise indicated <br />or specified herein, the pipe shall have the minimum <br />wall thickness according to class designation for <br />diameters shown. All pipe shall be given a minimum <br />factory hydrostatic test of 500 pounds per square inch. <br />02625-1 <br />
