Ordering Information

Orders for material to this specification should include the following, as required, to describe the desired material adequately:

1 Quantity (feet, centimetres, or number of lengths),

2 Name of material (austenitic steel pipe),

3 Process (seamless (SML) or heavily cold worked (HCW) ),

4 Grade,

5 Size (NPS or outside diameter and schedule number or average wall thickness),

6 Length (specific or random),

7 End finish (Section on Ends of Specification A 999/A 999M),

8 Optional requirements (product analysis, see Section 8; hydrostatic or nondestructive electric test, see Section 12),

9 Test report required (Certification Section of Specification A 999/A 999M),

10 Specification number, and

11 Special requirements or any supplementary requirements selected, or both.

 

Materials and Manufacture

Manufacture:

1 The pipe shall be manufactured by one of the following processes:

2 Seamless (SML) pipe shall be made by a process that does not involve welding at any stage of production.

3 Heavily cold-worked (HCW) pipe shall be made by applying cold working of not less than 35 % reduction in thickness of both wall and weld to a welded pipe prior to the final anneal. No filler shall be used in making the weld. Prior to cold working, the weld shall be 100 % radiographically inspected in accordance with the requirements of ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, latest revision, Paragraph UW-51.

4 At the option of the manufacturer, pipe shall be either hot finished or cold finished.

5 The pipe shall be free of scale and contaminating exogenous iron particles. Pickling, blasting, or surface finishing is not mandatory when pipe is bright annealed. The purchaser is permitted to require that a passivating treatment be applied to the finished pipe.

 

Heat Treatment

All pipe shall be furnished in the heat-treated condition in accordance with the requirements of Table 2. Alternatively, for seamless pipe, immediately following hot forming while the temperature of the pipes is not less than the specified minimum solution treatment temperature, pipes may be individually quenched in water or rapidly cooled by other means.

 

Grain Size:

The grain size of grades 304H, 316H, 321H, 347H, and 348H, as determined in accordance with Test Methods E 112, shall be No. 7 or coarser.

Hydrostatic or Nondestructive Electric Test

1 Each pipe shall be subjected to the nondestructive electric test or the hydrostatic test. They type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.

2 The hydrostatic test shall be in accordance with Specification A 999/A 999M, unless specifically exempted under the provisions of 12.3.

3 For pipe whose dimensions equal or exceed NPS10, the purchaser, with the agreement of the manufacturer, may waive the hydrostatic test requirement when in lieu of such test the purchaser performs a system test. Each length of pipe furnished without the completed manufacturer’s hydrostatic test shall include with the mandatory markings the letters “NH.”

4 Nondestructive Electric Test: Nondestructive electric tests shall be in accordance with Specification A 999/A 999M.

 

Supplementary requirements

Transverse tension test

Flattening test

Etching test

Radiographic examination

Stabilizing heat treatment

Intergranular corrosion test
