Product Description
Key Features
Load efficiency of 50% provides sufficient strength for most drilling conditions
Improved RQ tapered, course threads (3 threads per inch) ,increased taper and a reverse angle load flank provides an interlocking joint with increased strength and anti-jamming for easier make-up.
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.

Raw materials:
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.
Heat treatment control:
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 concentricity of the treated tubes will be tested in our lab.
Thread opening process:
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.
Additional thread treatment:
Surface of the threads will be cleaned to remove burr adhered after threads are opened.

Wireline Drill Rod vs. Conventional Drill Rod
| 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 |
Engineered for Reliable Connections: The enhanced-taper, 3-TPI RQ threads deliver smooth, jam-resistant make/break. Crafted from premium alloy steel, each tube delivers guaranteed concentricity, straightness, and uniform heat treatment for maximum performance and longevity.
Application
- Mineral exploration (gold, copper, nickel, lithium)
- Geotechnical surveys
- Geothermal well development
- Hydrological research
- Environmental monitoring
