    Surface Condition
    Pickling or shot blasting, Passivated, Black Phosphating.

     

    Material & Manufacture
    Pipe may be either hot finished or cold drawn with the finishing heat treatment 
     
     
    Heat Treatment : A / N+T  , N+T / Q+T  , N+T
     

     
    Hydrostatic Test
    Each length of pipe shall be subjected to the hydro-static test, 
    Unless otherwise specified in the purchase order, each length of pipe shall, at the option of the manufacturer, be subjected to the nondestructive electric test  in lieu of the hydrostatic test.
    When specified by the purchaser, pipe shall be fur- nished without hydrostatic test and without nondestructive examination.
    When specified by the purchaser, pipe shall be fur- nished with both the hydrostatic test and a nondestructive examination having been performed.
     
     
     
     
    Mechanical Tests 
    Transverse or Longitudinal Tension Test and Flatten- ing 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 (Note 7). For small lots, at least 1 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 (Note 7), but in no case less than 2 pipe.
     
    NOTE 7—The term “lot” applies to all pipe of the same nominal size  and wall thickness (or schedule) which is produced from the same heat of steel and subjected to the same finishing treatment in a continuous furnace; when final heat treatment is in a batch-type furnace, the lot shall include only that pipe which is heat treated in the same furnace charge.

     
    Hardness Test:
    For pipe of Grade P122, Brinell, Vickers, or Rock- well hardness tests shall be made on a specimen from each lot (see Note 7).
     
     
    Bend Test:
    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. The inside diameter of the bend shall be 1 in. [25 mm].
     
     
    Test specimens for the bend test specified in 13.3 shall be cut from one end of the pipe and, unless otherwise specified, shall be taken in a transverse direction. One test specimen shall be taken as close to the outer surface as possible and another from as close to the inner surface as possible. The specimens shall be either 1⁄2 by 1⁄2 in. [12.5 by 12.5 mm] in section or 1 by 1⁄2 in. [25 by 12.5 mm] in section with the corners rounded to a radius not over 1⁄16 in. [1.6 mm] and need not exceed 6 in. [150 mm] in length. The side of the samples placed in tension during the bend shall be the side closest to the inner and outer surface of the pipe, respectively.
