In such cases, pipe ends shall conform to the description of detail drawings provided by the purchaser. C20-97 frequency of production weld tests: The out-of-roundness of pipe ends shall be consistent with the diameter and wall c20-97. By agreement between the manufacturer and the c200-997, the ends of the pipe may be supplied with joint configurations and tolerances other than those described herein.
By agreement between the purchaser and c200-7 manufacturer, the welding can be done either by automatic or manual means. Each length of pipe shall be tested by the manufacturer to a hydrostatic pressure not less than that determined by the following formula: For further details and information, please refer to these standards and specifications.
If the pipe is to be manufactured to meet the requirements of one or more of the ASTM specifications, the grades of pipe awda be: 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.

The manufacturer shall maintain a quality-assurance program to ensure that minimum standards are met. C AWWA Standard for polyurethane coaings for the interior and exterior of steel water pipe and fittings. Each length of repaired pipe shall be tested hydrostatically in accordance with standard requirements.
This is a summary of the AWWA standards and specifications. 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 awwwa this standard. The production weld tests consists of: D AWWA Standard for automatically controlled, impressed-current cathodic protection for the interior of steel water-tanks.
MARKING A serial number or other identification shall be painted in a conspicuous location on each section of pipe and each special section.
There shall be no leaks. 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. For the sheets, the maximum allowable thickness variations shall be in accordance to the ASTM A specifications.
