This document 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 document. The requirements that define different levels of standard technical requirements for PSL-2 and PSL-3 are in AnnexG.
This document covers the following grades of drill-pipe:
gradeE drill-pipe;
high-strength grades of drill-pipe, gradesX, G and S;
enhanced H2S resistance drill pipe, grades D and F.
A typical drill-pipe configuration is given, showing main elements and lengths (see FigureB.1). The main dimensions and masses of the grades of drill-pipe are given in both SI units (see TableA.1) and in USC units (see TableC.1).
This document can also be used for drill-pipe with tool joints not specified by ISO or API standards.
By agreement between purchaser and manufacturer, this document can also be applied to other drill-pipe body and/or tool-joint dimensions. This document lists supplementary requirements that can optionally be agreed between purchaser and manufacturer, for testing, performance verification and non-destructive examination (see Annex E).
This document does not consider performance properties, nor performance degradation of the product when in service.
NOTE1 In this document, drill-pipe is designated by label1, label 2, grade of material (E, X, G, S, D and F), upset type and type of rotary shouldered connection. Designations are used for the purpose of identification in ordering.
NOTE2 Reference can be made to ISO10424‑2 or API Spec7-2 for the detailed requirements for the threading of drill-pipe tool joints.
NOTE3 Reference can be made to APIRP7G for the performance properties of the drill-pipe.
