ASME SA312 ASTM A312 TP310S Stainless-Steel Tubes
- Flattening Test—For material heat treated in a continuous furnace flattening tests shall be made on a sufficient number of pipes to constitute 5 % of the lot, but in no case less than 2 lengths of pipe.
- Hydrostatic or Nondestructive Test—Each pipe shall be subjected to the nondestructive electric test or the hydrostatic test
- Markings—Markings will adhere to prescribed specifications in A999/A999M and shall include the NPS or OD 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 section 12.3 on Hydrostatic or Nondestructive Electric Test, if applicable, and whether seamless (SML), welded (WLD), or heavily cold-worked (HCW). For Grades TP304H, TP316H, TP321H & TP347H, the marking shall also include the heat number and heat-treatment lot identification.
Note:
- Mill test certificates will be issued according to EN10204.3
- All tubes shall be supplied as per applicable ASTM A312 /A312M Specification.
