Description

High Strength Kelly Bar A Low Weight High Straightness High Wear Resistance

High Strength Kelly Bar Piling Q345B Material Customized Color For Rotary Rig

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.

1) Interlocking kelly bar

Interlocking kelly bar is used for drilling in dense sand,gravel and weak to strong rock .Interlocking kelly bar can be fully locked by mechanical locking system on each section.Kelly bar can be equipped with specially designed springs or pressure plates for shock absorbing purpose.

2) Friction kelly bar

Friction kelly bar is another type which the external key is composed of 3 or 6 wear -resistant strip without pressunrizing point .This kelly bar can transform pressure when it is working.Also can produce peripheral force and pass down the pressure force,can produce the friction force.This kelly bar has the advantage of operating sample ,drilling deep ,but with less pressure transmission.So this one is suitable for the soft and silt layer.
