API casing pipe is produced according to the API 5CT standard. It is most often used in underground construction projects to encase or protect utility lines from being damaged. 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 API 5CT Casing and Tubing Specification - Octalsteel

According to API 5CT standard, steel material used for making the pipe billet supplied shall be grain refining treatment. This steel shall contain one or more grain refining elements, such as a certain amount of aluminum, niobium, vanadium or titanium, so that the austenite grains of the steel Grain refinement. Heat Treatment
Heat treatment methods for API 5CT casing and tubing is an important factor to differ each grade. Products requiring heat treatment shall be subjected to full body and full length heat treatment. The heat-treated upsetting product should be heat treated full body, full length after upsetting. A separately heat tAPI Steel Grade Category And Color - API Coupling, Casing This grade is sensitive to SSC failures unless the temperatures are relatively high (> 175°F). The P110 grade is slightly more expensive than L80 Type 1 but usually less expensive than the C90 and T95 API restricted-yield grades. Q125Although not a specific API tubing grade, users can order Q125 API tubing. Type 1 chemistry is preferred.
According to American Petroleum Institute Standard API SPEC 5CT1988 1st edition, the steel grade of API 5CT oil casing pipe can be divided into ten types, including H-40, J-55, K-55, N-80, C-75, L-80, C-90, C-95, P-110 and Q-125. API 5CT Pipes, API 5CT Casing Pipe, OCTG Casing Tubing API 5CT 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 i.e. PSL-1, PSL-2 & PSL-3.The requirements for PSL-1 are the basis of this standard.

There are different grades such as H40, J55, K55 up to Q125. The Grade L80 Steel Tubing is a medium level grade which has medium level of elements including 9% chromium. The material is strong and is used in high temperature, high pressure systems.

API 5CT Grade Q125 Oil Well Drilling Casing Pipes are comparatively low steel grade. Inspection. Physical properties are checked and each length hydrostatically tested, normally to only 3,000 psi in the plain end (unthreaded) condition. The following are also checked:Dimensions; Lengths; Straightness; Weights; Part of this inspection is to drift all lengths.
