Oil Exploration

Oil exploration equipment operates under high-pressure, severe-corrosion and strong-vibration conditions, where part failure is costly. Hanweite machines motor casings, high-pressure valve bodies and sealed structural parts for exploration equipment customers, focusing on wall thickness uniformity, sealing surface accuracy and pressure resistance.

Industry Solutions

• Exploration motor casing: thin-wall deep-cavity part, wall thickness tolerance ±0.1mm
• High-pressure valve body: sealing surface Ra0.4, pressure hold test at 1.5 times working pressure
• Sealed structural part: O-ring groove dimensions and roughness strictly controlled
• Connecting flange: flatness ≤0.01mm, bolt hole position tolerance compliant

Typical Parts and Processes

Thin-wall deep-cavity parts use 5-axis simultaneous machining in a single setup with dedicated tooling to reduce clamping deformation; key parts are stress-relieved after machining.

Quality Assurance

Pressure parts undergo piece-by-piece pressure hold tests with records kept; key dimensions are fully inspected by CMM, with inspection reports provided with the goods.
