Casing pipe end thread type
The International Standard specifies the technical delivery conditions for steel pipes (casing, tubing, plain end casing liners and pup-joints) and accessories. It 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).
- 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, the sizes, masses, wall thicknesses, grades and applicable end finishes are defined.
It may also be applied to tubulars with connections not covered by ISO/API standards.
