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

• A / N+T

• N+T / Q+T

• N+T

• 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.

• For pipe whose diameter exceeds NPS 25 and whose diameter to wall thickness ratio is 7.0 or less shall be subjected to the bend test instead of the flattening test.

• Other pipe whose diameter equals or exceeds NPS 10 may be given the bend test in place of the flattening test subject to the approval of the purchaser.

• The bend test specimens shall be bent at room temperature through 180 without cracking on the outside of the bent portion.
