Fully Robotic Automation, Robotized & Automated Processing
Accuracy of threads will determine the use effects and life time of drill rod and casings. CNC latches and form cutter are used in thread opening processing to minimize error made by anthropic factors.
Load efficiency of 30% provides sufficient strength for most drilling conditions
SINOCOREDRILL only choose the best steel tubes in the market to manufacture our rods and pipes. Spot check will be conducted after the steel tubes delivered to company. We will make sure the compositions and specifications match the inspection report form the suppliers.
Whole rod Heat treated significantly increases rod life
Rod Pin thread crest is hardened to nominal 50-55 HRC to eliminate damaging ‘adhesion’ wear Eliminates the transfer of wear material back and forth as seen between threads of equal hardness, leading to large scale galling and joint seizing Heat treatment will greatly improve the material strength and increase the thread wear life of the rods and casings. We conduct either tru-wall or both ends heat treatment to the tube body. After heat treatment, strength, hardness, straightness and concentrically of the treated tubes will be tested in our lab.

| Features | Wireline Drill Rod Vs. | Conventional Drill Rod |
|---|---|---|
| Core Retrieval | Through wireline-no need to pull rods | Must extract full drill string |
| Time Efficiency | Very fast, ideal for deep coring | Slow, labor-intensive |
| Cost per Meter | Lower in deep-hole drilling | High due to tripping time |
| Core Quality | Minimal disturbance; higher recovery | More disturbance risk |
| Best Application | Exploration, mining, geothermal | Shallow or rotary projects |
| Safety | Fewest heavy rod-handling cycles | More manual handling required |
Moving up in size, the HQ drill rod provides an even larger core diameter, making it invaluable for projects requiring substantial sample volumes or when drilling through highly fractured or unstable ground. The larger annulus around the core barrel allows for better flushing and stabilization, reducing the risk of core wash-out and improving recovery rates. HQ rods are often employed in advanced exploration, mine development, and large-scale geotechnical investigations.
