  • This International Standard specifies the technical delivery conditions for steel pipes (casing, tubing, plain end casing liners and pup-joints) and accessories. This International Standard is applicable to the following connections in accordance with ISO 10422 or API Spec 5B:

  • - short round thread casing (STC);

  • - long round thread casing (LC);

  • - buttress thread casing (BC);

  • - extreme-line casing (XC);

  • - non-upset tubing (NU);

  • - external upset tubing (EU);

  • - integral joint tubing (IJ).


  • For such connections, this International Standard specifies the technical delivery conditions for couplings and thread protection.


  • For pipes covered by this International Standard, the sizes, masses, wall thicknesses, grades and applicable end finishes are defined.


  • This International Standard may also be applied to tubulars with connections not covered by ISO/API standards.
