3. Insufficient tightening torque, resulting in drilling jamming accidents or excessive torque on the well, causing secondary tightening underground, causing the female buckle to swell and the male joint thread to be damaged; The joint strength does not meet the standard requirements.
4. The presence of corrosive media or unreasonable mud ratio in the well can cause corrosion fatigue of the pipe body.
