HaiRun Kelly Bar:
Using the international advanced bond type distribution technology, the internal and external bond overlap,
Improve the reliability and performance of the kelly bar.
All the high - strength alloy pipe is used to ensure the size precision, excellent mechanical properties and
welding adaptability of the special steel tube (such as core section) for the two time enhanced heat treatment,
greatly improving the performance of the kelly bar.
All keys of the kelly bar are made of high strength and high quality alloy structural steel, and the inner key is
used as a whole structure, which greatly improves the wear resistance and life of the internal and external key
strips, thereby reducing the failure rate and maintenance of the drill rod.
Reasonable pipe system configuration, so that the thickness of the key bar thickness, improve the transmission
torque and the ability of the kelly bar, reduce the emergence of the drill rod, rod, rolling and other failures.
The unique double blocking ring structure, increasing the length of the total length of the kelly bar, not only solves
the problem of easy deformation of the steel tube end, but also increases the coaxial degree and the bending
performance of the kelly bar.
Professional deep hole, Ying Yan, sand pile hole construction technology, optimize the construction scheme
and a strong construction technology team, to avoid the difficulties caused by the complex formation, the hairun
kelly bar is to improve the efficiency of drilling, the first choice for maximum benefit.
