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

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.
