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.
