BWL HWL NWL PWL Drill Rod
BWL HWL NWL PWL Wireline Drill Rod
BQ NQ HQ PQ Wireline Drill Rod Core Barrel Inner tube and Outer tube series
BWL HWL NWL PWL Wireline Drill Rod for Core Barrel Inner tube / Outer tube
Specifications:
1. high quality alloy tube
2. thru-wall heat treated tube body
3. consistent concentricity, straightness
4. tapered threads
Raw materials:
ROSCHEN just use 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.
Material: 30CrMnSiA or 45MnMoB (A grade), XJY850, BG850(B grade), RS950, Eruopean/US Standard 40/41
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.
Afterwards, the tread surface will be phosphated to improve surface conditions.
