Interlocking Kelly Bar Friction Kelly Bar Great Pressure Transmission​

 

Kelly Bar is the key part for a Piling Rig, to make high reliable Kelly bar, we have to follow rules as below:
 
1. Top quality material
 
2. High welding quality
 
3. Appropriate heat treatment
 
4. Professional design

 

Kelly bar are designed for the purpose of transferring torques and pressures onto a drilling tool. Kelly bar is the main component of rotary rig,its quality directly affects the performance of the whole machine. There is two kinds:friction kelly bar,interlocking kelly bar.

 

1) Interlocking kelly bar:

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 formations, (weak) weathered rock, hard strata construction.

The 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

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

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