Why Choose JuPai for Oil & Gas Parts Machining
Advanced 5-Axis CNC Machining for Complex Oil & Gas Components
Equipped with advanced 5-axis CNC machining centers, we manufacture complex oil & gas components featuring intricate geometries, deep cavities, and multi-angle features in a single setup. This reduces setup errors, improves dimensional accuracy, and ensures consistent quality for high-pressure and mission-critical applications.
Ultra-Tight Tolerances (±0.002 mm) for Sealing-Critical Components
We deliver high-precision CNC machining with ultra-tight tolerances for oil & gas components where sealing performance is critical. Precise dimensional control ensures proper assembly, minimizes leakage risks, and enhances reliability in high-pressure and sour service environments.
High-Pressure Capability (Up to 20,000 PSI)
Our machining capabilities are engineered for extreme pressure environments up to 20,000 PSI, including wellhead systems, subsea equipment, and hydraulic fracturing applications. We ensure structural integrity, fatigue resistance, and long-term performance under continuous high-load conditions.
Expertise in Corrosion-Resistant & NACE-Compliant Materials
We specialize in machining high-performance materials such as Inconel (625/718), Duplex and Super Duplex stainless steels, titanium alloys, and high-strength alloy steels. NACE-compliant material options are available for sour service applications, ensuring superior corrosion resistance and durability in H₂S and other harsh environments.
Comprehensive Quality Control with CMM & NDT Inspection
Our quality assurance system spans the entire production process, including CMM inspection, in-process monitoring, and non-destructive testing (UT, RT, PT). Full material traceability and detailed inspection reports ensure compliance with oil & gas industry standards and help reduce project risk.
