NQ Wireline Drill Rod

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.

Surface of the threads will be cleaned to remove burr adhered after threads are opened.

The NQ drill rod is perhaps the most commonly used size in mineral exploration and geotechnical drilling worldwide. It strikes an excellent balance between core diameter, drilling depth capability, and overall operational efficiency. NQ rods allow for the recovery of larger, more representative core samples, which are crucial for accurate geological logging and resource estimation. Their robust design also enables deeper drilling in challenging formations.
