About This Item

 

Full Description

ISO 11961:2018 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 ISO 11961:2018 but those that define different levels of standard technical requirements for PSL-2 and PSL-3 are also given.

ISO 11961:2008 covers grade E drill pipe and the high-strength 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.

ISO 11961:2018 can also be used for drill pipe with tool joints not specified by ISO or API standards.

By agreement between purchaser and manufacturer, ISO 11961:2018 can also be applied to other drill-pipe body and/or tool-joint dimensions. ISO 11961:2018 lists supplementary requirements that can optionally be agreed between purchaser and manufacturer, for testing, performance verification and non-destructive examination.

ISO 11961:2018 does not consider performance properties.
