View MoreIn the drilling industry, components operate at the extreme edge of material science. Whether penetrating deep rock layers in mining or extracting energy resources, drilling machinery forgings are subjected to immense torsional loads, high-frequency vibration, and abrasive underground slurry. A failure in a drill string or a drive shaft deep underground results in catastrophic retrieval costs and project delays. To ensure "zero-failure" performance, the industry relies on forged components that offer superior fracture toughness and fatigue resistance.
At ACE Group, we combine massive forging power with precision heat treatment. Utilizing the 15-ton electro-hydraulic hammers at Jiangsu ACE Energy Technology, we produce the high-strength alloy components required to transmit power and resist impact in the harshest subsurface conditions.
Drilling components face "Cyclic Torsional Stress"—the twisting force required to break through rock. Unlike cast parts, which can harbor internal microscopic voids that act as "crack starters," ACE Group drilling machinery forgings are engineered for maximum density.
Grain Flow Optimization: Our forging process aligns the metal's internal grain flow along the axis of the drill shaft or connector, providing maximum resistance to snapping and twisting.
Refined Microstructure: By upsetting and drawing the high-quality alloy steel, we eliminate porosity, ensuring the part can withstand heavy loads and harsh operating conditions without brittle fracture.
| Performance Metric | ACE Group Forged Drilling Parts | Standard Cast/Bar Components |
| Torsional Strength | Exceptional (Optimized grain) | Moderate (Risk of shear failure) |
| Fatigue Resistance | High (Resists vibration cracks) | Low (Prone to stress risers) |
| Impact Toughness | Superior (Forged core density) | Variable (Potential internal voids) |
| Operational Life | Extended 40% - 60% | Standard |
In deep drilling, any deviation in alignment (eccentricity) creates massive vibration that destroys bearings and gearboxes.
Concentricity Error ≤0.02mm: At Yancheng ACE Machinery, we maintain a "mounting hole concentricity error of ≤0.02mm." This ensures that drill shafts and connectors rotate with perfect balance, preventing eccentric loads and reducing wear on the entire drill string.
Precision Threading: Forged connectors are precision-machined to ensure a firm and reliable connection, which is vital for maintaining hydraulic pressure in "Mud-Pulse" telemetry systems.
Drilling machinery is often stored in harsh port environments or exposed to corrosive drilling fluids. Yancheng ACE Surface Treatment Technology provides a specialized solution:
Heavy-Duty Coating: Our power & free chain spraying line applies a powder coating with a one-time thickness of 400μm.
The Benefit: This creates a weather-resistant, anti-corrosion barrier that protects the external structural components of the drilling rig from salt-air and chemical erosion during transport and operation.
| Component Type | Typical Materials | Key Drilling Application |
| Drive Shafts & Kellys | 4145H, 4340, 34CrNiMo6 | Transmission of primary rotation torque |
| Drill Bit Bodies | High-Strength Alloy Forging | Housing for PDC or Tricone cutters |
| Mud Pump Forgings | 42CrMo4, F22 | High-pressure fluid circulation |
| Connectors & Subs | AISI 4140, Stainless Steel | Stable structural connection of drill pipe |
