Kelly bar type

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.

Hairun auger drill detailed description and production processes:

1.Both groups of welding production line
2.Square Head: We according to BAUER kelly bar's desiging to re-desing this square head. 
Its have advantages of simple using, good looking and etc.
3.Add Rotary drill bottom reinforcing ring strengthen applicability
4.Reasonable to calculate the thickness and the materials used to make it effective to strengthen the 
applicability of wear and scalability
5.Pretty skilled welding technology and welding technology
