API Spec 5CT

Specifies the technical delivery conditions for steel pipes (casing, tubing, plain end casing liners and pup-joints) and accessories. This standard is applicable to the following connections in accordance with API Spec 5B:

-short round thread casting (STC);
-long round thread casing (LC);
-buttress thread casing (BC);
-extreme-line casing (XC);
-non-upset tubing (NU);
-external upset tubing (EU);
-intergal joint tubing

This edition of API Spec 5CT is the modified adoption of ISO 11960, Petroleum and natural gas industries-Steel pipes for use as casing or tubing for wells. This specification contains the API monogram annex as part of the U.S. national adoption.
