Detailed description

IMT Full Interlock Kelly Bar is composed by three weld-on ribs with continuous concave and convex keys (see chart)

 

During the drilling process, the downward thrust is transmitted to drill bucket directly by rotation power of Rotary head inner ribs and Kelly bar outer ribs at any time. This type of Kelly bar is the best one of transferring pressure, especially for hard ground and frozen oil layer. In the drilling process, every continuous steps can form pressure point to reduce wear and tear of local pressurization key lines, also to avoid the stick problem that Kelly pipe is deformation always in a part pressurization.

 

When drilling progress, driving the inner convex concave tooth key and the outer convex concave tooth key uniformly forms good engagement, the advantage is force uniform, not easy to stick pipe, particularly to improve work efficiency.  It has gotten high praise for home and abroad rotary rig user.

 

Now this type Kelly bar has been applied for patent, the patent No. is 201420542679.2.

the transmission pressure of this drill pipe is the best, especially constructing to the hard layer formation and permafrost; every site of the drill pipe can be formed the pressure point in the course of the drilling, reducing the partial rack (key) of the pressured abrasion, and also to avoid the drill in a part of the pipe wall deformation caused by the pipe-sticking, at the same time, the convex and concave tine distributed in the driving internal key and external key have a good meshing. In the pressurized part of the formation of multi-point pressure, stress and stability are not sticking cloth, excellent work to improve the efficiency of rotary drilling by many customers!
