Material & Manufacture

Pipe may be either hot finished or cold drawn with the finishing heat treatment noted below.

Heat Treatment

  • A / N+T
  • N+T / Q+T
  • N+T
Mechanical Tests Specified
  • Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test
  • For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot. For small lots, at least one pipe shall be tested.
  • For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe.
Notes for Hardness Test:
  • P11 shall not have a hardness not exceeding 250 HB/265 HV [25HRC].
