Process of manufacture

The various grades and groups of pipe furnished to this International Standard shall be made to a fine-grain practice. Steel made to a fine-grain practice contains one or more grain-refining elements, such as aluminium, niobium (columbium), vanadium or titanium in amounts intended to result in the steel having a fine austenitic grain size.

 

Process requiring validation

Final operations performed during pipe manufacturing that affect attribute compliance as required in API 5CT (except chemical composition and dimensions) shall have their processes validated.

Those processes requiring validation are:

  • for seamless, as-rolled pipe: final reheating practice and hot sizing or stretch-reducing. If applicable, upsetting, cold finishing;
  • for seamless, heat-treated pipe: heat treatment;

 

Grain size — Grades C90 and T95

Prior austenitic grain size shall be ASTM 5 or finer (determined in accordance with ISO 643 or ASTM E112).

 

Sulfide stress cracking test — Grades C90 and T95

Test and re-test requirements

For each heat, manufacturers shall demonstrate that the product meets or exceeds the minimum SSC threshold using one of the ANSI-NACE TM0177-96 test methods given below. If the purchaser requires an SSC threshold higher than the minimum, or requires a specific test method from the list below, agreement shall be reached between purchaser and manufacturer. For Methods A and D, sub-size or alternative specimens shall only be used following agreement with the purchaser. When Method D sub-size or alternative specimens are required, acceptance criteria shall be agreed between the purchaser and manufacturer.

 

Labels and sizes

In the dimensional tables in this International Standard, pipe is designated by labels and by size (outside diameter). The outside diameter size of external-upset pipe is the outside diameter of the body of the pipe, not the upset portion.
