1) Interlocking kelly bar

Interlocking kelly bar with great pressure transmission and good perfomance. There are 3 rigid parts between drilling pipes to transfer greater pressure from embedding cylinder. Even at the hard geologic condition it can transfer greater pressure.Stair key, organization transmission, the outside key is made by highly wear-resisting tempering steel. For for drilling in dense sand,gravel and weak to strong rock.

 

2) Friction kelly bar

Friction kelly bar is another type,it does need unlock the joint of its inner and outer line so that it is convenient and fast to lift the bar. Non-stair key, the outside key is made by high wear-resisting tempering steel. is suitable for layer of soft ground and mud, mud, (mud) sand, gravel.

 


3. All the outer keys have undergone special heat treatment.

1. Adopt the advanced technology of 6-key design in the world and standard modular design.

2. All the tubes made in China are specially made seamless alloy tube,which guarantees the accuracy of the sizes,location,physical properties and easy welding.

4. Square-stub through forging and heat treating have excellent mechanical properties.

5. Increase pressing position wear resistant property.
