BS EN ISO 11961:2008 Petroleum and natural gas industries. Steel drill pipe
BS EN ISO 11961 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 BS EN ISO 11961. The requirements that define different levels of standard technical requirements for PSL-2 and PSL-3 are in Annex G. BS EN ISO 11961 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. The main dimensions and masses of the grades of drill-pipe are given in both SI units and in USC units. BS EN ISO 11961 can also be used for drill-pipe with tool joints not specified by ISO or API standards. By agreement between purchaser and manufacturer, BS EN ISO 11961 can also be applied to other drill-pipe body and/or tool-joint dimensions. BS EN ISO 11961 lists supplementary requirements that can optionally be agreed between purchaser and manufacturer, for testing, performance verification and non-destructive examination. BS EN ISO 11961 does not consider performance properties. Contents of BS EN ISO 11961:
