API 5B oil casing and tubing are structural components used to line the wellbore during drilling and production, providing stability and preventing collapse in oil and gas wells. This supplier offers casing and tubing in sizes ranging from 4-1/2 to 20 inches in outer diameter, with wall thicknesses between 5.21 mm and 16.13 mm, catering to various well depths and pressure requirements. The products conform to Api 5ct, Api 5d and Api 5l standards, ensuring compatibility with global oilfield practices.
The casing and tubing are available in multiple grades, including J55, K55, M65, L80, C95, N80, C90, T95, P110 and Q125, each designed for specific mechanical properties and corrosion resistance. Typical material compositions for these grades include carbon-manganese steel for lower grades and alloy steel with added chromium or nickel for higher grades, enhancing strength and durability in challenging downhole conditions. The ends are typically threaded and coupled, with types such as Stc, Ltc or premium connections available.
These products are essential for well construction, serving as surface casing, intermediate casing or production casing, depending on the well design. Oil and gas operators, drilling contractors and service companies source these materials to ensure well integrity and efficient hydrocarbon extraction. Buyers should confirm the specific grade, size and connection type required for their application, as well as the availability of additional services such as threading, heat treatment or coating.

Before ordering, verify the specific grade, size and connection type required for your well design, as mismatches can lead to installation issues or well integrity failures. Request mill test reports and compliance certificates to confirm the casing and tubing meet Api 5ct, Api 5d or Api 5l standards, and check for additional certifications such as ISO 9001 for quality management systems.
Discuss lead times, as casing and tubing may require custom manufacturing based on size and grade availability. Clarify Incoterms, with FOB or CIF being common for shipments from China, and agree on payment terms such as TT or LC. Ensure packaging and handling procedures meet export standards to prevent damage during transit, particularly for threaded ends.
Upon receipt, inspect the casing and tubing for physical defects, dimensional accuracy and threading quality. Verify the heat number and traceability markings match the mill test reports. Conduct a pressure test if possible to confirm integrity, and store the products in a dry environment to prevent corrosion before installation.
