Drill pipes, casings, and tubing used in wells are prone to corrosion under complex well conditions such as high pressure, high temperature, strong corrosion, and heavy wax deposition:

Loss of structural strength.

Corrosion perforation of the tube body.

Seal failure of the threads.

Wax deposition and blockage in the tube body.

Reduction in single-well production.

High well repair costs, or even abandonment.
