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.
