This International Standard specifies the technical delivery conditions for steel drill-pipes with upset pipe-body
ends and weld-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 and PSL-3). The requirements for PSL-1 form
the basis of this International Standard. The requirements that define different levels of standard technical
requirements for PSL-2 and PSL-3 are in Annex G.
This International Standard covers the following grades of drill-pipe:
⎯ grade E drill-pipe;
⎯ high-strength grades of drill-pipe, grades X, G and S.
A typical drill-pipe configuration is given, showing main elements and lengths (see Figure B.1). The main
dimensions and masses of the grades of drill-pipe are given in both SI units (see Table A.1) and in USC units
(see Table C.1).
This International Standard can also be used for drill-pipe with tool joints not specified by ISO or API
standards.
By agreement between purchaser and manufacturer, this International Standard can also be applied to other
drill-pipe body and/or tool-joint dimensions. This International Standard lists supplementary requirements that
can optionally be agreed between purchaser and manufacturer, for testing, performance verification and
non-destructive examination (see Annex E).
This International Standard does not consider performance properties.
NOTE 1 In this International Standard, drill-pipe is designated by label 1, label 2, grade of material (E, X, G and S),
upset type and type of rotary shouldered connection. Designations are used for the purpose of identification in ordering.
NOTE 2 Reference can be made to ISO 10424-2 or API Spec 7-2 for the detailed requirements for the threading of
drill-pipe tool joints.
NOTE 3 Reference can be made to API RP 7G for the performance properties of the drill-pipe.
