Coverage

This standard specifies the technical delivery conditions for steel drill pipe with upset pipe body ends and welded on tool joints for use in drilling and production operations in petroleum and natural gas industries for three product specification levels (PSL-1, PSL-2, PSL-3). The requirements for PSL-1 form the basis of this standard. The requirements that define different levels of standard technical requirements for PSL-2 and PSL-3 are provided.

This standard covers the following grades of drill pipe:

- grade E;

- high-strength (grades G, S, X, and V);

- sour service (grade SS).

This standard can also be used for drill pipe with tool joints not specified by other standards. By agreement between purchaser and manufacturer, this standard can also be applied to other drill pipe body and/or tool joint dimensions. This standard also lists supplementary requirements (SRs) that may be agreed upon between the purchaser and manufacturer for testing, performance verification, and nondestructive examination (NDE). This standard does not consider performance properties.

NOTE 1 In this standard, drill pipe is designated by label 1, label 2, grade of material (E, X, G, S, SS, and V), upset type, and type of rotary shouldered connection (RSC); designations are used for identification in ordering.

NOTE 2 See API 7-2 for the detailed requirements for the threading and gauging of drill pipe tool joints.

NOTE 3 See API 7G for the performance properties of the drill pipe.

Application of the API Monogram

If the product is manufactured at a facility licensed by API and is intended to be supplied bearing the API Monogram, the requirements of Annex A apply.
