It is widely used in the cementing projects to serve as the structural retainer for the wall of oil and gas
wells or wellbore. It is inserted into a well bore and cemented in place to protect both subsurface formations
and the wellbore from collapsing and allow drilling fluid to circulate and extraction to take place.

The main steel grade of API 5CT: API 5CT J55, API 5CT K55, API 5CT N80, API 5CT L80, API 5CT P110. 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.
