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 Annex G. This document covers the following grades of drill-pipe: ?? grade E drill-pipe; ?? high-strength grades of drill-pipe@ grades X@ 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 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 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 drillpipe 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. NOTE 1 In this document@ drill-pipe is designated by label 1@ 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. 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.
