It shall include a certified welding awwq 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.

Defects in seamless pipe or in the parent metal of welded pipe will be considered unacceptable when the depth of the defect is greater than Each length of repaired pipe shall be tested hydrostatically in accordance with standard requirements.

MARKING A serial number or other identification shall be painted in a conspicuous location on each section of pipe and each special section. For plates, the maximum allowable thickness variation shall be 0. For the sheets, the maximum allowable thickness variations shall be in accordance awa the ASTM A specifications. By agreement between the purchaser and the manufacturer, the welding can be done either by automatic or manual means.

All spiral, longitudinal, and girth seams used in the manufacture of the pipe shall be full-penetration welded butt joints. The maximum radial offset tolerance on the plates is: 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.


Each length of pipe shall be tested by the manufacturer to a hydrostatic pressure not less than that determined by the following formula: 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.

The test pressure shall be held for sufficient time to observe the weld seams. There shall be no leaks. 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 out-of-roundness of pipe ends shall be consistent with the diameter and wall thickness. Any out-of-roundness shall be limited to a smooth oval that may be jacked back to a circular shape.

In such cases, pipe ends shall conform to the description of detail drawings provided by the purchaser. This is a summary of the AWWA standards and specifications.

For further details and information, please refer to these standards and specifications. Yield strength, min Ksi Mpa. Tensile strength ,min Ksi Mpa. 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 manufacturer shall maintain a quality-assurance program to ensure that minimum standards are met. The finished pipe shall be free from unacceptable defects.

A serial number or other identification shall be painted in a conspicuous location on each section of pipe and each special section. If the pipe is to be manufactured to meet the requirements of one or more of the ASTM specifications, the grades of pipe shall be: 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 weld shall be reasonably uniform width and height for the entire length of the pipe.

The procedures, the welding operators as well as all operators shall be qualified under Sec. The production weld tests consists of: The pipe shall be substantially round. 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.

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.
