API 5CT Tubing Pipe
Our mill manufactures premium, API 5CT-certified seamless tubing pipes engineered explicitly for high-pressure downhole oil and gas extraction, fluid production strings, and heavy-duty well completion systems. We guarantee strict drift dimension clearance, superior high-tensile collapse resistance, verified thread connection tolerances, and premium anti-corrosion finishes under direct [2-Hour Rapid Quote] mill terms.
Frustrated by delayed manufacturer responses while your high-stakes drilling schedule or critical infrastructure procurement deadline closes in? Eliminate downhole production failures and secure your mill-verified testing certificates immediately.

Technical QA/QC Verification
• 100% Traceable API MTC Compliance: Every delivery is accompanied by traceable EN 10204 3.1 Mill Test Certificates (MTC) proving exact chemical composition heat numbers, hydrostatic burst test records, ultrasonic weld verification, and hardness mapping. Fully ready for visual auditing by SGS, Bureau Veritas, or Intertek.
• Capital Security Guarantee: We remove cross-border transaction risks completely by securing long-term high-volume production delivery contracts under 100% Irrevocable Letters of Credit (L/C) at sight terms.
Anti-Rust Packaging & Ocean Logistics
• Fortified Heavy-Gauge Bundling Layout: Tubing pipes are bundled into rigid hexagonal groups using high-tensile metal banding bands, complete with durable synthetic crane slings to ensure safe loading and prevent pipe-to-pipe friction wear during sea voyages.
• Extended Destination Port Demurrage: Our logistics desks coordinate 14 to 21 days of complimentary container or breakbulk demurrage at your discharge port to ease customs documentation and coordinate local domestic transit.
Tubing is a relatively small-diameter pipe that is run into a well to serve as a conduit for the passage of oil and gas to the field surface facilities for processing. Tubing must be adequately strong to resist loads and deformations associated with production and workovers. Further, tubing must be sized to support the expected rates of production of oil and gas.
Sizes and Materials
Tubing pipes are manufactured in seamless and welded execution, in the size range of 1.050 to 5 1/2 inches (consult this article to see the AP5CT tubing pipes sizes) and in the following material grades: H-40, J-55, K-55, N-80, L-80, C-90, T-95, P-110, Q-125
End Connections
The main types of connections for tubing pipes are NUE (non-upset), EUE (external upset) and premium. Corrosion resistance under sour service conditions is a very important OCTG characteristic, especially for casing and tubing.

Application Areas
Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments.
Factory workshop
With a commitment to excellence, innovation, and sustainability, the company has established itself as a trusted partner in the international steel industry.After nearly two decades of relentless endeavour, our client base now spans over 110 countries and regions across Europe, the Middle East, South America, and Southeast Asia.
