Semi-finished Casing Joint
The Semi-finished Casing Joint offered by Xiamen Bluesea Piping Systems Co., Ltd. is cast from carbon steel or low‑alloy steel to meet API 5CT specifications. The joint is supplied in a semi‑finished condition suitable for final machining and threading, and it is available in the common grades L80, P110 and N80 used for oil‑field casing strings. Each joint conforms to the dimensional tolerances required for API‑certified wellbore assemblies.
Typical industry practice for API 5CT casings includes outside diameters from 4.5 in to 20 in and wall thicknesses ranging from 0.25 in to 2.5 in, with tensile strengths of 120 - 150 ksi for L80 and up to 165 ksi for P110. Heat treatment is normally performed by normalising or quenching‑tempering to achieve the specified mechanical properties, and the surface finish is generally a mill finish with a roughness (Ra) of ≤ 1.6 µm. These parameters allow the joint to withstand the high pressures and temperatures encountered in drilling operations.
Drilling contractors and OCTG distributors typically import the semi‑finished joints for on‑site machining, threading and coupling into complete casing strings. Xiamen Bluesea does not publish a minimum order quantity, so buyers should confirm the required volume and any custom size specifications with the sales team. Prospective customers are encouraged to request the material test report and the API 5CT certification before finalising the purchase.

Sourcing Semi-finished Casing Joint from Xiamen Bluesea Piping Systems Co., Ltd. - China Import Guide
Before ordering, verify the exact API grade, outside diameter and wall thickness required for your casing design. Request the latest API 5CT certification and a material test report that confirms tensile strength and chemical composition. This ensures the joint meets the mechanical specifications of your well program.
Logistics are usually handled from the Xiamen port. Agree on Incoterms such as FOB or CIF and confirm the freight forwarder’s charges. Payment terms are commonly T/T or a confirmed letter of credit; ask the supplier to state their preferred method and any documentary requirements before shipment.
Arrange a pre‑shipment inspection to check casting quality, dimensional tolerances and surface finish. A third‑party inspection agency can verify the mill finish, wall thickness and any heat‑treatment records. Ensure the joint is packed in moisture‑resistant crates to protect the steel surface during sea transport.
