API 5CT – Specification for Casing and Tubing
Spec 5CT specifies the technical delivery conditions for steel pipes (casing, tubing, plain end casing liners, and pup joints) and accessories.
Applicable to the following connections in accordance
（1）short round thread casing (STC);
（2）long round thread casing (LC);
（3）buttress thread casing (BC);
（4）extreme-line casing (XC);
（5）non-upset tubing (NU);
（6）external upset tubing (EU);
（7）integral joint tubing (IJ).
This standard specifies the technical delivery conditions for steel pipes (casing, tubing, and pup joints), coupling stock, coupling material, and accessory material and establishes requirements for three Product Specification Levels (PSL-1, PSL-2, PSL-3). The requirements for PSL-1 are the basis of this standard. The requirements that define different levels of standard technical requirements for PSL-2 and PSL-3, for all grades except H-40, L-80 9Cr, and C110, are contained in Annex H. This standard can also be applied to tubulars with connections not covered by API standards,Not applicable to threading requirements.
API 5B-Specification for Threading, Gauging, and Thread Inspection of Casing, Tubing, and Line Pipe Threads
API 5B is the standard specification for threading, gauging, and inspection of Casing, Tubing and line pipe threads.
Spec 5B covers dimensions and marking requirements for API Master thread gauges. Additional product threads and thread gauges, as well as instruments and methods for the inspection of threads for line pipe, round thread casing, buttress casing, and extreme-line casing connections, are included. It is applicable when so stipulated in the API standard governing the product. The inspection procedures for measurements of taper, lead, height, and angle of thread are applicable to threads having 111/2 or less turns per in. (111/2 or less turns per 25.4 mm). All thread dimensions shown without tolerances are related to the basis for connection design and are not subject to measurement to determine acceptance or rejection of product.
