What parts does a complete rotary kelly bar consist of?

What parts does a complete rotary kelly bar consist of?
1. Kelly eye: It is a component that connects the kelly bar and the lifting unit.
2. Bolt: Fix the flange.
3. Baffle: It can prevent the kelly bar from being carried when the kelly bar is lifted.
4.Damping rubber: reduce the impact on the rig during drilling and protect the rig.
5.External key: used to transmit torque and pressure, and play a guiding role.
6. Taper key: play a guiding role and facilitate the pressurization and unlocking the block.
7. Pressure block: used to transfer pressure.
8.Pallet: Flowing water protects the end of the kelly bar.
9.Spring: play a dual role of protecting the kelly bar and the rig.
10. Kelly stub: transfer pressure and torque to the drilling tools.
11. Retaining ring: play a role of limiting and positioning.
12. Swivel: positioning, wear-resistant.
13. Internal key: used to transmit torque and pressure, play a role in positioning and guiding.

Advantages

1. Excellent strength and stability:
Made of high-quality steel with excellent tensile, compressive and torsional strength, it can withstand extreme drilling pressure and complex geological conditions.
The well-designed interlocking structure ensures that each section of drill pipe is connected tightly and firmly, maintaining stability during drilling and reducing shaking and deviation.

2. Efficient torque transmission:
The unique design enables the torque to be evenly and efficiently transmitted from the top of the drill pipe to the drill bit, improving drilling efficiency and reducing energy loss.

3. Outstanding wear resistance:
Surface treatment and material selection make it has good wear resistance, which prolongs the service life of the drill pipe and reduces the frequency and cost of replacement.
