1) High penetration rate and high drilling efficiency.
2) High core recovery rate.
3) Long bit life and lower labor intensity
4) Adopt abrasion resistant material.
Raw materials:
We 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.
Afterwards, the tread surface will be phosphated to improve surface
conditions.
