Adopting internationally advanced key distribution technology, the overlapping integration of internal and external keys improves the reliability and performance of the kelly bar.

All kelly bar are made of high-strength alloy high-quality pipes to ensure the dimensional accuracy, excellent mechanical properties and welding adaptability of the kelly bar. Special steel pipes (such as core-section steel pipes, etc.) are subjected to improved secondary strengthening heat treatment, which greatly improves the kelly bar. torsional performance.

All  of the kelly bar are made of high-strength, high-quality alloy structural steel and are fully strengthened. The internal keys adopt an overall arc plate structure, which greatly improves the wear resistance and life of the internal and external key bars, thereby reducing the failure rate of the kelly bar. and maintenance.

Reasonable piping configuration maximizes the key strip thickness and steel pipe wall thickness of the kelly bar, improves the kelly bar’s ability to transmit torque and pressurized drilling, and reduces the occurrence of kelly bar problems such as stuck rods, belt rods, and rolling keys. .

The unique double retaining ring structure increases the guide length when the kelly bar is fully extended, which not only solves the problem of easy deformation of the steel pipe end, but also increases the coaxiality and anti-bending performance of the kelly bar when it is fully extended, reducing the cost of the kelly bar. When drilling under pressure, there is a probability of inclined holes.

Professional kelly bar technology for deep hole, hard rock, and sandy pile hole construction, optimized construction plans and a strong construction technical team can eliminate the difficulties caused by construction in complex strata. Jiujie kelly bar can improve drilling efficiency and obtain The first choice for maximum efficiency.

A kelly bar is a critical component of any drilling operation. It is a square or hexagonal steel bar that transmits torque to a drill bit or other tool. Choosing a high-quality kelly bar is essential for ensuring safety, efficiency, and productivity.   

Technical Features of Kelly Bars

Here are some of the key technical features of kelly bars:

• Material: Kelly bars are typically made from high-quality steel that is heat-treated to ensure strength and durability. The specific type of steel used will vary depending on the application.   
   
• Size and shape: Kelly bars are available in a variety of sizes and shapes. The size and shape of the kelly bar will depend on the specific drilling application.
• Design: The design of the kelly bar is critical for ensuring optimal performance. The design must be optimized for the specific drilling application.   
   
• Connections: The connections on the kelly bar must be strong and reliable. The connections must be able to withstand the high torque and stresses that are placed on the kelly bar during drilling operations.   
   
• Surface finish: The surface finish of the kelly bar is important for reducing friction and wear. A smooth surface finish will help to improve the performance of the kelly bar and extend its life.

Benefits of Choosing a Good Kelly Bar

There are many benefits to choosing a good kelly bar. Some of the most important benefits include:

• Safety: A high-quality kelly bar is less likely to fail, which can help to prevent accidents and injuries.   
   
• Efficiency: A good kelly bar can help to improve drilling efficiency by reducing downtime and increasing penetration rates.   
   
• Productivity: A good kelly bar can help to increase overall productivity by reducing the need for repairs and replacements.
• Cost savings: Although a good kelly bar may cost more upfront, it can save money in the long run by reducing downtime, repairs, and replacements.

How to Choose a Good Kelly Bar

When choosing a kelly bar, there are several factors to consider. Some of the most important factors include:

• Size and type: The size and type of kelly bar will depend on the specific drilling application.
• Material: The kelly bar should be made from high-quality steel that is heat-treated to ensure strength and durability.   
   
• Design: The design of the kelly bar should be optimized for the specific drilling application.
• Manufacturer: It is important to choose a kelly bar from a reputable manufacturer with a proven track record of quality and reliability.

Conclusion

A kelly bar is a critical component of any drilling operation. Choosing a high-quality kelly bar is essential for ensuring safety, efficiency, and productivity. When choosing a kelly bar, it is important to consider the size, type, material, design, and manufacturer.
