Marking:
In addition to the marking specified in Specification ,A999/A999M, the marking shall include the NPS (nominalpipe size) or outside diameter and schedule number or average
wall thickness, heat number, and NH when hydrotesting is not performed and ET when eddy-current testing is performed or UT when ultrasonic testing is performed. The marking shall
also include the manufacturer’s private identifying mark, the marking requirement of 12.3, if applicable, and whether seamless (SML), welded (WLD), or heavily cold-worked
(HCW). For Grades TP304H, TP316H, TP321H, TP347H, TP348H, and S30815, the marking shall also include the heat number and heat-treatment lot identification. If specified in the
purchase order, the marking for pipe larger than NPS 4 shall include the weight.
