Key Features 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.

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. Size available as followings: Wireline series: AQ, BQ, NQ/NRQ, HQ,/HRQ PQ/PHD Casing: AW, BW, NW, HW, HWT, PW,SW Chinese Standard: S56, S59, S75, S95, S110, S130, S57X, S75A, S95A Wireline Drill Rod vs. Conventional Drill Rod
The PQ/PHD drill rod is the largest standard size in the “Q” series, designed for applications demanding the largest possible core samples. This size is typically used for bulk sampling, large-diameter geotechnical boreholes, or when drilling through very difficult ground conditions that necessitate maximum stability and flushing capacity. While slower to drill due to their weight and larger diameter, PQ rods provide unparalleled sample volume and hole integrity. Application
