Description:
Brief?Introductions?of?Drill Rod
Our drill rods are suitable to drill deep holes.
The drill rods are widely used for geological and mineral, metallurgy, mining, oil drilling and hydrology industries.
We got feedback from drillers who use Yaheng& acute;s drill rods, Yaheng& acute;s drill rods reached over 2,000 meters depth.
Features of drill rod:
1) Made of high quality alloy steel
2) Be heat-treated
3) Reasonable structure, reliable performance and high using efficiency.
4) Good concentricity, high precision and long service life.
?
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.
