API Casing Coupling, Tubing Couplings
The API Casing and Tubing Couplings from Hebei Borun Steel Trade Co., Ltd are manufactured to API 5CT and 5B standards, providing a secure connection between casing and tubing joints in oil and gas wells. Available in steel grades ranging from H40 to Q125, these couplings support a wide spectrum of downhole pressure and temperature conditions. Tubing couplings cover dimensions from 2-3/8 to 4-1/2 inches, while casing couplings range from 4-1/2 to 20 inches to match standard pipe sizes.
End finishes include NUE and EUE for tubing couplings, and STC, LTC, or BTC for casing couplings, each tailored to specific thread types and sealing requirements. The couplings are color-coded by grade for easy identification: J55/K55 in bright green, N80/L80 in red, P110 in white, C75 in blue, and C90 in brown, as per API 5CT. This color-coding system helps prevent misapplication in the field and ensures compliance with industry traceability practices.
These couplings are used in onshore and offshore drilling operations to maintain well integrity and facilitate the assembly of casing and tubing strings. Contractors and operators source them for new well construction, workover projects, and repair operations. Packaging options include wooden cases or pallets, with custom requests accommodated to meet specific shipping or storage needs.

Sourcing API Casing Coupling, Tubing Couplings from Hebei Borun Steel Trade Co., Ltd - China Import Guide
Before placing an order, confirm the steel grade and dimensional specifications match your well’s requirements, particularly for high-pressure or corrosive environments. Verify the end finish (NUE/EUE for tubing, STC/LTC/BTC for casing) aligns with your pipe’s thread type to ensure a secure connection. Request API 5CT/5B compliance certificates to validate the couplings’ adherence to industry standards.
Clarify Incoterms (e.g., FOB or CIF) and payment terms (such as L/C or T/T) with the supplier to avoid misunderstandings during shipment. Discuss lead times for manufacturing and delivery, as custom or large orders may require additional time. Wooden cases or pallets are standard, but confirm if alternative packaging is needed for your logistics.
Inspect the couplings upon receipt for correct color coding, dimensional accuracy, and thread integrity to ensure they meet API specifications. Request hydrostatic test reports and material certificates to confirm performance under downhole conditions. Document all inspections and retain records for compliance, warranty, and future reference.
