Scope
1   Scope 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 H 2 S 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
