Maintenance of Drill Pipes for Rotary Drilling RIGS

The drill pipe of a rotary drilling rig, as an important component, its condition directly affects the construction efficiency and safety. Proper maintenance of drill pipes can extend their service life and reduce maintenance costs. Now let's talk about the key points of drill pipe maintenance.

1. Daily cleaning: After each operation, the surface of the drill pipe should be promptly rinsed with a high-pressure water gun to remove adhering soil and concrete residues. Pay special attention to the threaded connection points. Don't let impurities affect the next installation.

2. Lubrication maintenance: Regularly apply special lubricating grease to the connection parts and sliding surfaces of the drill pipe to reduce friction. Generally, check the lubrication condition every 50 hours of operation and reapply it in time.

3. Wear inspection: Regularly check the degree of wear of the drill pipe, especially the helical blades and drill teeth of the drill pipe. When components with excessive wear are found, they must be replaced immediately to prevent the fault from expanding.

4. Anti-rust treatment: When idle for a long time, apply anti-rust oil to the drill pipe and place it in a dry and well-ventilated area. If rust appears on the surface, it needs to be sanded and re-rusted to prevent the rust from worsening.

5. Correct operation: Do not overload the drill pipe during operation and avoid sudden lifting or lowering. Construction strictly in accordance with the operating procedures can greatly reduce the damage to the drill pipe caused by improper operation.

6. Storage Standards: When storing drill pipes, they should be placed horizontally to prevent bending and deformation due to gravity. When stacking in multiple layers, soft pads should be used to separate the layers to prevent mutual squeezing and wear.

Proper maintenance of drill pipes is the foundation for ensuring the efficient operation of rotary drilling RIGS. Daily cleaning, lubrication, inspection, rust prevention and other tasks may seem trivial, but they can effectively reduce the occurrence of faults, lower maintenance costs and improve construction efficiency. From now on, paying attention to the maintenance of drill pipes is to ensure the smooth progress of the project.
