-Company Profile-

China OAK Oilfield Pipe Manufacturing Co., Ltd.
Built for Oil, Built to Last

Brand Positioning

As a globally recognized leader in advanced oilfield tubular solutions, China OAK Oilfield Pipe Manufacturing Co., Ltd. (OAK) stands at the forefront of mission-critical OCTG (Oil Country Tubular Goods) and drilling technologies. Headquartered in Beijing with state-of-the-art production hubs in Tianjin and Cangzhou, OAK serves as a strategic partner to energy majors across six continents, delivering tailored systems for extreme operational environments.

Corporate Philosophy
Rooted in the triad of Operational Excellence, Advanced Innovation, and Key Reliability, OAK’s mission is to redefine the boundaries of tubular performance. We engineer resilience into every product, ensuring operational continuity where pressures peak, temperatures fluctuate wildly, and corrosive forces threaten conventional solutions.

Value Proposition
OAK empowers the global energy sector to drill deeper, produce smarter, and operate safer. Our solutions mitigate downtime risks in high-stakes projects—from Arctic permafrost to high-pressure/high-temperature (HPHT) reservoirs—through precision metallurgy, AI-driven manufacturing, and lifecycle technical support.

Development History
Founded as a domestic tubular specialist, OAK rapidly evolved into an innovation powerhouse through:

• 2010s: Strategic R&D investments in extreme-environment metallurgy.

• 2018: Commissioning of AI-optimized production lines, boosting annual capacity to 200,000 tons.

• 2022: Global certification sweep (API 5CT/5DP/7-1, ISO 11960/14310) and entry into Latin America’s pre-salt basins.

Technical Highlights

• HPHT Mastery: Casing systems rated for 250°C/15,000 psi with proprietary anti-deformation threading.

• Thermal Recovery Dominance: Steam injection alloys enduring 620°C cyclic thermal shocks (+50% lifespan vs. API N80).

• Corrosion Defense: CRA (Corrosion Resistant Alloy) grades with 30% enhanced H₂S/CO₂ resistance (per NACE TM0177).

• Arctic/Subsea Expertise: -60°C impact-tough tubulars meeting DNV-OS-F101 Arctic standards.

• Smart Manufacturing: Industry 4.0-enabled facilities achieving ±0.05mm dimensional accuracy.

Compliance & Certification

• Standards: API 5CT/5DP/7-1, ISO 9001:2015/11960/14310, DNV-OS-F101.

• Testing Protocols: Full-spectrum NACE, Charpy V-notch, and SSC/HIC testing.

• Sustainability: ISO 14001-certified low-carbon production processes.

Market Validation
OAK’s solutions drive success in:

• Middle East: Sour gas field casing for 20+ projects (H₂S >50,000 ppm).

• Russia: Arctic-grade drill pipes enabling year-round Yamal Peninsula operations.

• Americas: HPHT-compliant tubing for 6,000m+ pre-salt wells.

• Africa: Thermal recovery systems boosting heavy oil output by 22% in Niger Delta fields.

Global Footprint

With products deployed in 28 countries and joint technical centers in Dubai, Houston, and Kuala Lumpur, 

OAK blends localized expertise with world-class engineering—proving that when energy challenges 

escalate, the answer is etched in steel.
