Kelly bar is the key part of a rotary rig, transfer the torque of the rotary power head and the pressure of the rotary rig system to the drilling tools and its quality affects the performance of the whole machine directly.

A kelly bar consists of 2-5 telescopic tubular section with a system of drive keys and lock recesses weld onto their outer surface.

Based on the rich manufacturing experience and by absorbing the advanced technology we have two kinds of kelly bar, interlocking and friction.

Frictional kelly bar needn't unlock the joint of its inner and outer lining so that it is convenient and fast to lift the bar. Non-stair key, friction transmission the outside key is made by highly wear-resisting tempering steel. For layer of soft ground and mud, mud, (mud) sand, gravel

Interlocking kelly bar is of great pressure transmission and good anti-contortion perfomance. There are 3 rigid parts between drilling pipes to transfer greater pressure from embedding cylinder. And even at the hard geologic condition it can transfer greater pressure and drill in. Stair key, organization transmission, the outside key is made by highly wear-resisting tempering steel. For soft fromations, (weak) weathered rock, hard strata construction.

1. The advantages of our Kelly bar, such as low weight, high strength, high abrasion-resistance, high-reliability are safeguarded.

2. Main body made of alloy hot-treated specially enjoy both high hardness and perfect welding performance, high abrasion-resistance leads to high-reliability.

3. Heat treatment is widely used in the key parts such as drive key to improve wear resistance

4. Small clearance and high-precision mating of the drill pipe ensure its good working order and service performance.

5. Fulfill the rotary drilling rig full torque operation.
