2023-12-25 Anti-corrosion steel pipes are metal bodies buried underground. However, due to the use environment, despite careful construction, general steel pipes will inevitably age easily, and the steel pipes will still have damage and defects. To extend the life of the steel pipes, it is necessary to perform
