MARKING A serial number or other identification shall be painted in a conspicuous location on each section of pipe and each special section. By agreement between the purchaser and the manufacturer, when the diameter and the wall thickness of the pipe are such that the capacity of the testing equipment is exceeded by these requirements, the test pressures may be reduced or other non destructive test methods may be used.
When the pipe is to be fabricated to meet the standard requirements; the plates, the sheets, or the coils shall be selected in accordance to the following physical properties and specifications.
The procedures, the welding operators as well as all operators shall be qualified under Sec.
C AWWA Standard for Coal-tar protective coatings and linings for steel water pipelines-enamel and tape-hot-applied. C AWWA Standard for Cold-applied petrolatum tape and petrolatum wax tape coatings for the exterior of special sections, connections, and fittings foe buried steel water pipelines.
Each length of pipe shall be tested by the manufacturer to c2000-97 hydrostatic pressure not less than that determined by the following formula: Defects in seamless pipe or in the parent metal of welded pipe will be considered unacceptable when the depth of c2009-7 defect is greater than This is a summary of the AWWA standards and specifications.
By agreement between the manufacturer and the purchaser, the ends of the pipe may be supplied with joint configurations and tolerances other than those described herein. The finished pipe shall be free from unacceptable defects.
C American National Standart for Protective fusion-bonded epoxy coatings for the interior and exterior surfaces of ductile-iron and gray-iron fittings for water supply service. By agreement between the purchaser and the manufacturer, the welding can be done either by automatic or manual means. In such cases, pipe ends shall conform to the description of detail drawings provided by the purchaser. Each length of repaired pipe shall be tested hydrostatically in accordance with standard requirements.
C AWWA Standard for polyurethane coaings for the interior and exterior of steel water pipe and fittings. The manufacturer shall maintain a quality-assurance program to ensure that minimum standards are met.
C American National Standart for Ductile-iron pipe, centrifugally cast, for water or other liquids.

Unless specified by the purchaser, the wall thickness and weight tolerances for welded pipe shall be governed by the requirements of the specifications to which the plates or sheets are ordered.
The maximum radial offset tolerance on the plates is: C AWWA Standard for Heat-shrinkable cross-linked polyolefin coatings for the exterior of special sections, connections, and fittings for steel water pipelines.
C American National Standart for Rubber-gasket joints for ductile-iron pressure pipe and fittings. Ends to be fitted with flanges shall be grinded longitudinal and spiral weldsat ground flush for a sufficient distance to allow proper installation of the flange.
All work performed and material furnished under this standard may be inspected by the purchaser, but such inspection shall not relieve the manufacturer of responsibility to furnish material and perform work in accordance with this standard. The weld shall awwa reasonably uniform width and height for the entire length of the pipe.
C American National Standart for Ductile-iron compact fitting, for water service. The pipe shall be substantially round.
The production weld tests consists of: There shall be no leaks. For plates, the maximum allowable thickness variation shall be 0. C AWWA Standard for Cold-applied tape coatings for the exterior of special sections, connections, and fittings for steel water pipelines. The frequency of production weld tests: There shall be at least one set of weld-test specimens taken of each size, grade, and wall thickness from work performed by each production machine and each operator at a minimum of every ft.
It shall include a certified welding inspector AWS QC1 to verify that welders and welding procedures are qualified, procedures are being followed with limitation of testing, and quality-assurance functions are being implemented. C American National Standart for Polyerthylene encasement for ductile-iron pipe systems. C American National Standart for Flanged ductile-iron pipe with ductile-iron or gray-iron threaded flanges.
All spiral, longitudinal, and girth seams used in the manufacture of the pipe shall be full-penetration welded butt joints. The out-of-roundness of pipe ends shall be consistent with the diameter and wall thickness.
F AWWA Standard for matched die-molded, fiberglass-reinforced plastc weir plates, scum baffles, and mounting brackets. Yield strength, min Ksi Mpa. For the sheets, the maximum allowable thickness variations shall be in accordance to the ASTM A specifications. Any out-of-roundness shall be limited to a smooth oval that may be jacked back to a circular shape.
