Do you know about the loading and unloading and maintenance of drill pipes? Take a look at it: Install and check the drill pipe, whether the joint is abnormal, whether the size meets the use requirements, take timely treatment measures for the drill pipe that cannot meet the use requirements, and strictly prohibit the use of the drill pipe that still cannot meet the requirements after taking measures.
Do you know about the loading and unloading and maintenance of drill pipes? Take a look at it:
1. Installation inspectiondrill pipe, Whether the joint is abnormal, whether the size meets the use requirements, take timely treatment measures for drill pipes that cannot meet the use requirements, and strictly prohibit the use of drill pipes that still cannot meet the requirements after taking measures.
2. For the drill pipe with critical use requirements, feasible protection measures shall be selected during installation.
3. Protect the surface rigidity of the drill pipe joint. It is strictly forbidden to polish the joint blindly and destroy its surface hardness without measurement.
4. During installation, check again whether the joint is complete and the pin hole is smooth, especially whether the pin is in good condition. It is strictly prohibited to use the pin with large expansion and burrs. Hammering the pin must be isolated with rigid and soft materials, and it is recommend to use red copper rod hammering for installation.
5. It is strictly prohibited to use materials with rigidity greater than pin-threading for pin-threading for disassembly type. It is necessary to use symmetrical blow to disconnect the drill pipe. At the same time, symmetrical blow is the best. It is strictly prohibited to use vigorous equipment for hammering in a single direction. Forced use will inevitably cause hidden damage to the drill pipe and frame.
6. Standbydrill pipeAnti-rust treatment must be done. For drill pipes stored for a long time, they must be rolled and stored at 180 ° every week to prevent losses caused by natural bending of storage.
7. For drill pipe pins that are difficult to disassemble, the first choice is to grind holes with small grinding wheels, drill holes with electric drills for heating, hammering with electric hammers, symmetrical rotating strikes and other methods. Secondly, electric welding and pin puller disassembly are used. It is really necessary to protect the integrity of convex and concave joints as much as possible by oxygen cutting to ensure that they can be repaired to the original use requirements.
Drill pipe should be regular maintenance, the only way to ensure that the equipment to play its effectiveness.
