What should I do if there is a buckle during the drilling pipe connection process

Date: Jun. 05, 2024

In the process of connecting drill pipes, if there is a snap, the following steps can be taken to handle it:
1、 Preliminary judgment and response
Judging the degree of buckle: First, determine whether the buckle is mild or severe. A slight buckle may only cause a brief increase in resistance, while a severe buckle may result in inability to rotate or disassemble.
Immediately stop the operation: Once a buckle phenomenon is found, the connection operation should be stopped immediately to prevent further damage to the drill pipe or connecting components.

2、 Inspection and cleaning
Check the connecting components: carefully inspect the male and female buckles to see if there are any impurities, oil stains, or other foreign objects blocking them, which may cause buckles.
Cleaning threads: Use appropriate cleaning tools (such as wire brushes) to clean the surface of threads from oil, dirt, and other impurities, ensuring that the thread surface is clean.
Check for thread damage: Check for any damage or deformation to the threads, and if so, repair or replacement may be necessary.
3、 Lubrication treatment
Apply thread grease: Apply an appropriate amount of thread grease to the cleaned threads to increase lubrication and reduce the possibility of jamming.
Control the application amount: The application amount of thread grease should be moderate. Excessive application may lead to the accumulation of oil stains, while insufficient application may result in insufficient lubrication.
4、 Reconnect
Alignment: Ensure that the male and female buckles are aligned to avoid misalignment or tilting that may cause buckles.
Slow Buckling: When reconnecting, it should be done slowly to avoid excessive force that may cause jamming or damage.
5、 Special handling methods
Mechanical stretching method: If the buckle is severe, you can try using mechanical stretching method to stretch the drill pipe with external force to release the buckle. However, this method is only suitable for slight jamming situations and requires careful operation to avoid damaging the drill pipe.
Acid treatment method: In specific situations, acid treatment method can be used to dissolve solid substances blocked between threads, but this method may cause corrosion to drill pipes and connecting components, so it should be used with caution.
Magnetic adsorption method: If the buckle is caused by magnetic material, you can try using magnetic adsorption method to suck out the magnetic material and release the buckle.
6、 Precautions
Avoid violent operation: When handling buckles, violent or coercive means should be avoided to avoid damaging the drill pipe or connecting components.
Seeking professional help: If you are unable to solve the buckle problem on your own, you should seek professional help and advice in a timely manner.
By following the above steps and precautions, it is possible to more effectively handle the clamping problem during the drilling pipe connection process, ensuring the safety and reliability of the drilling pipe connection.
