Beijing Jietai Haoli Technology Development Co., Ltd. is one
comprehensive enterprise that produces and sells rotary drilling
kelly bars ,drilling tools,piling rigs spares and piling rig
maintenance.
Based on the integration of Bauer, Soilmec and IMT interlocking
kelly bars,we studied one big (multi) interlocking kelly bar,which
have applied for patents. This kind kelly bar has the following
advantages:
(1) The pressurized area is increased, which is 3-4 times the
pressurized area of other type kelly bars;
- The pressurized force is evenly distributed, avoiding long-term
concentrated stress the phenomenon of premature breakage of the
kelly bars so effectively prolongs the service life of the drill
pipes;
- The stability of kelly bars when during the drilling process is
more better due to the pressure at multiple points, which avoids
the the phenomenon of drilling offset, inclined hole or expanding
hole.
The practice has shown that, this big (multi) interlocking kelly
bar has more advantage of increased pressurized area, extended
pressurized linear distance, uniform force distribution, and better
drilling stability rather than the original interlocking type kelly
bars. This type kelly bar is more suitable for the construction of
large-diameter and hard rock formations.
