' SECTION 02625 <br /> WATER MAINS <br /> DUCTILE IRON PIPE AND FITTINGS <br /> ' 1 . 01 SCOPE <br /> This section covers cast ductile iron pipe and cast ductile iron fittings for <br /> ' water mains . <br /> 1 . 02 GENERAL <br /> A . Ductile iron pipe shall be allowed for use as water pipe where <br /> compatible with the specific conditions of the project. The use of <br /> material other than ductile iron may be required by IRCDUS <br /> ' during construction permit review, or by IRCDUS field personnel , if <br /> it is determined that ductile iron pipe is unsuitable for the particular <br /> application . <br /> ' B . All ductile iron pipe shall be manufactured in accordance with <br /> AWWA Specification C- 151 and shall be Class 50 minimum . All <br /> ' ductile iron pipe crossing under roadways shall be Pressure Class <br /> 350 minimum . <br /> ' C . Unless specifically indicated otherwise , restrained joint <br /> underground piping shall be manufactured restrained bell and <br /> spigot and above ground piping shall 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 accordance with AWWA <br /> Specification C151 (ANSI A21 . 51 -86 ) , or latest revision . Cast ductile iron <br /> ' shall have a minimum tensile strength of 60 , 000 psi , with a minimum yield <br /> strength of 42 , 000 psi . Pipe wall thickness shall be computed in <br /> accordance with AWWA Specification C150 (ANSI A21 . 50-81 ) , or latest <br /> ' revision , using the physical characteristics cited above , with a minimum <br /> working pressure of 150 psi and a Laying Condition "Type 2 . " Unless <br /> otherwise indicated or specified herein , the pipe shall have the minimum <br /> ' wall thickness according to class designation for diameters shown . All <br /> pipe shall be given a minimum factory hydrostatic test of 500 pounds per <br /> square inch . <br /> ' 02625 - 1 <br /> F :\Utilities\UTILITY - ENGINEERING\WTP - North RO\N RO Brine Line Discharge - UCP#2208\BID DOCUMENTS North <br /> County RO\BID DOCUMENTS\02625 WM Ductile Iron Pipe and Fittings .doc <br />
