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).
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.
This International Standard can also be used for drill-pipe with tool joints not specified by ISO or API standards.
This International Standard is based on API Spec 5D and API Spec 7.
This edition of API Spec 5DP is the identical national adoption of ISO 11961, Petroleum, petrochemical and natural gas industries-Steel drill pipe. This specification contains the API Monogram Annex as part of the U.S. national adoption.
