As the backbone of Heibei Constellation Energy’s global well control equipment supply chain, our three modern manufacturing bases integrate R&D, production, testing, and delivery to uphold the company’s core mission of “safety first, quality paramount." Over five years, these facilities have enabled us to serve major oil and gas clients worldwide—including PetroChina, CNOOC, Chevron, and Shell—by delivering specialized, high-reliability well control solutions. Unlike general-purpose manufacturing sites, our bases are purpose-built for blowout preventers (BOPs) and supporting systems, ensuring precision, compliance with international standards (API 6A, GB/T 22513, ISO 9001), and flexibility for custom client needs. This introduction outlines our manufacturing infrastructure, capabilities, quality systems, and operational strengths, highlighting how we translate technical expertise into industry-leading products.

Our three bases are strategically located in Hebei and Jiangsu provinces—key industrial hubs with robust logistics, mature supply chains, and access to skilled talent. Hebei’s strength in heavy industry provides easy access to high-quality raw materials (alloy steel, specialized rubber) and mechanical manufacturing expertise, ideal for BOP production. Jiangsu’s advanced precision machining capabilities and proximity to major ports (Shanghai, Ningbo) optimize production of supporting equipment and global export efficiency. This distribution ensures operational resilience, reduced lead times, and seamless collaboration across product lines.

Spanning a combined 25,000 square meters, these bases specialize in R&D and production of BOPs, BOP accessories, and BOP control systems. Each facility features specialized workshops designed for the full product lifecycle:

• R&D & Prototyping Workshop (1,800 sq.m.): Equipped with 3D printers, CNC milling centers, and hydraulic test benches, this hub uses SolidWorks and AutoCAD for 3D modeling and finite element analysis (FEA), cutting development cycles by 30%. It enables rapid prototyping and performance simulation for extreme drilling environments.
• Structural Fabrication Workshop (6,500 sq.m.): Houses CNC lathes, vertical machining centers, and large boring mills capable of processing workpieces up to 5 meters in length. A vacuum heat treatment facility ensures alloy steel components withstand pressures up to 15,000 psi and temperatures from -40°C to 121°C—critical for HPHT and deepwater operations.
• Hydraulic Control System Workshop (3,200 sq.m.): Produces hydraulic control panels, accumulator units, and remote control systems using precision assembly lines and testing stations. Components from global suppliers (Bo sch Rexroth, Parker Hannifin) undergo rigorous inspection to ensure reliability.
• Assembly Workshop (4,800 sq.m.): Features 6 dedicated lines for annular, ram, and combination BOP stacks, with ergonomic workstations and digital traceability systems. Technicians receive specialized training in torque specifications and seal installation to minimize errors.
• Testing & QC Laboratory (2,100 sq.m.): Conducts high-pressure testing (up to 20,000 psi), fatigue cycling (10,000+ cycles), corrosion resistance testing, and non-destructive testing (ultrasonic, magnetic particle) to validate product integrity.

Capacity & Efficiency: Combined annual output includes 120+ BOP units, 150+ control systems, and 5,000+ accessories. Using SAP S/4HANA ERP software, lead times are 45 days for standard products and 60–90 days for custom solutions—faster than the industry average of 90–120 days.

Specializes in API 6A-standard gate valves (manual/hydraulic) and choke & kill manifolds, leveraging precision machining for flow control and pressure resistance:

• Valve Machining Workshop (5,200 sq.m.): Uses CNC turning centers and grinding machines to achieve tight tolerances for valve seats and gates. A hardening facility applies wear-resistant coatings for extended service in abrasive environments.
• Manifold Fabrication Workshop (4,800 sq.m.): Equipped with pipe bending machines and orbital welding systems, adhering to API 16C standards. Each manifold undergoes X-ray inspection and pressure testing up to 15,000 psi.
• Assembly & Testing Workshop (3,500 sq.m.): Integrates valve and manifold assembly with leak testing, flow capacity verification, and pressure cycling. Hydraulic flushing stations remove contaminants to ensure smooth operation.

Capacity & Logistics: Annual production includes 800+ gate valves (2–20 inches, 2,000–15,000 psi) and 200+ manifolds. Proximity to Shanghai Port enables container shipping within 3–5 days of production completion.

Our manufacturing relies on state-of-the-art equipment and integrated technology systems to ensure precision and efficiency:

• CNC Machining: Over 50 5-axis CNC centers (Mazak, Haas) deliver tolerances as tight as ±0.005 mm for complex BOP components, with CAD/CAM integration reducing setup time.
• Specialized Fabrication: Vacuum heat treatment furnaces, orbital welding machines, and rubber molding equipment ensure component durability and performance.
• Digital Integration: ERP systems, digital traceability software, and PLC programming stations (Siemens) streamline production planning, inventory management, and quality control.

All equipment is calibrated regularly to maintain accuracy, and our team undergoes continuous training to operate advanced machinery and software.

Quality control is embedded in every production stage, aligned with global standards and industry best practices:

• Raw Material Inspection: All steel, rubber, and hydraulic components are tested for material integrity before production, with suppliers audited annually.
• In-Process Quality Checks: Digital workstations document each assembly step, with inspections at key milestones (machining, heat treatment, assembly) to identify defects early.
• Final Testing: Every product undergoes pressure, fatigue, corrosion, and functional testing, with test results stored in a searchable database for traceability.
• Certifications: Our facilities hold ISO 9001 quality management certification, and products comply with API 6A, API 16C, and GB/T 22513 standards—validated by third-party audits and client acceptance testing.

We maintain a robust supply chain and operational framework to ensure reliability and speed:

• Supplier Management: Partnerships with global component suppliers ensure consistent quality, with safety stock held for critical parts to avoid production delays.
• Production Scheduling: ERP-driven planning balances custom orders and standard production, optimizing resource utilization and on-time delivery rates (consistently above 98%).
• Logistics Coordination: Dedicated logistics teams manage domestic and international shipping, with preferred partnerships with major freight carriers to minimize transit times.

Our factories are committed to advancing manufacturing capabilities through:

• Technology Upgrades: Regular investment in new equipment and software (e.g., AI-powered quality inspection tools) to enhance precision and efficiency.
• Process Optimization: Lean manufacturing principles reduce waste, while employee feedback drives workflow improvements.
• Market Adaptation: R&D collaboration with clients ensures our production processes align with emerging industry needs (e.g., deepwater drilling, renewable energy integration).
