Interlocking Kelly Bar Friction Kelly Bar Great Pressure Transmission​

 

Kelly bars planned and produced by our company are of interlocking and friction type. Our aim is to transfer to the drilling tools both the torque and the pressure produced by the drilling machine. The planning of kelly bars is entrusted to the experienced technicians and engineers.We can plan and produce kelly bars for any kind of drilling machines. The high quality of the components, all certified steels for the high mechanical features together with the strict procedures of the quality system ISO 9002, allows us to guarantee the highest reliability.It is very important to pay attention to the following notice:
 
  • the maximum length of the kelly bar and then its drilling deepness depends, mainly, from the kind of drilling machine, from the line pull max of the winch and from the height of the tool used;
  • the planning of the kelly bar depends on the kind of soil to drill;
  • for each kelly bar it is necessary to know the maximum torque applicable;
  • the real working time and performance of the kelly bars are very high if all the instructions of use and maintenance are strictly followed;
  • the length of the kelly bar can be realised according to the client request;
  • the weight of the kelly bar can have a tolerance of ± 5/10%

 

1. 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.

2. 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.
