    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.
