6 Section Friction Kelly Bar

 

Telescopic segmented Combination, Flexible and Efficient – The mulit section Friction Kelly Bar with torque transfer from 120 – 500 kNm 6 drive keys with large lock recesses Shock absorbing system by spring assembly Standardized square kelly drive stub for all drilling tools

 

The six-section friction kelly bar is comprised of six meticulously constructed segments, each of which has been subjected to rigorous craftsmanship and quality testing. The unique friction connection ensures a secure and stable bond between the segments, which can effectively transmit torque and withstand significant pressure during drilling.

In terms of material selection, the drill pipe is constructed from high-strength, wear-resistant and tough special steel, which ensures excellent performance over time and resistance to deformation or damage.

 

The six-section design provides excellent scalability and adaptability. The length can be flexibly adjusted to meet the requirements of different drilling depths and working conditions, whether in shallow strata or deep drilling operations.

 

 

 

1. Lightweight and High-Strength.

 

2. Advanced Six-Key Layout Distribution Technology

 

3. Segmented design for flexible assembly based on geological conditions.

 

4. Frictional connections ensure stable pile driving.

 

5. Efficient transmission system to increase pile driving speed.

 

6. Eeasy fix and maintainance.

 

 

Telescopic Friction Kelly Bar Parameter

 

 

 

 

1. Provide Drilling Equipment Details:
- Inform us of the brand and model of the equipment where the Kelly bar will be installed (e.g., Bauer BG28, Soilmec SR30, Sany SR40, Mait HR180). Alternatively, provide the torque and pressure specifications of the equipment's powerhead.

 

2. Select the Kelly Bar Style:
- Please choose the style of Kelly bar you need: Interlocking Kelly Bar, Friction Kelly Bar, or Full Lock Kelly Bar.

 

 

3. Detail the Square Head Size:
- Provide the size of the square head of the Kelly bar. For instance, Bauer typically uses a 200mm x 200mm Kelly box, while Sany uses 150mm x 150mm, 200mm x 200mm, or 250mm x 250mm Kelly boxes.

 

 

4. Specify Dimensions and Requirements:
- Let us know the outer diameter and length of each single section of the Kelly bar you need. If you're unsure, provide the total drilling depth required, and we can determine the number of sections and their lengths based on your requirements. For example, specify if you need a Kelly bar with a 406mm outer diameter, 4 sections of 11 meters each, or if you need a total drilling depth of 38 meters.

 

 

5. Example Request:
- For example, if your equipment is a Soilmec SR40, and you require 2 Interlocking Kelly Bars with a diameter of 355mm, 4 sections each, and each section is 9 meters long, we will supply you with a 355mm, 4-section, 9-meter long Interlocking Kelly Bar.

 

When purchasing a kelly bar for a rotary drilling rig, it's important to look for bars made of high-quality steel with strong mechanical features. No matter whether buying kelly bars new or used, it's also good to look for bars that include origin and quality certificates to guarantee their reliability and longevity. All kelly bars can be purchased with a damping noise system, which can help to reduce the disruptive, high-frequency noises produced during operation; a damping noise system comprises of a phono-absorbent material applied to the outer scope of the kelly bar, which is protected by a steel plates.

 

- Alternatively, if you use a Bauer BG40 rotary drilling rig and need an Interlocking Kelly Bar with a diameter of 470mm to drill piles with a depth of 28 meters, we will calculate the number of sections and the length of each section required based on the total drilling depth and provide the appropriate size Kelly Bar.

This approach ensures that we can accurately fulfill your requirements and provide the appropriate Kelly Bar for your equipment and project needs.
