Anti corrosion steel pipe refers to the steel pipe processed by anti-corrosion process, which can effectively prevent or slow down the corrosion phenomenon caused by chemical or electrochemical reaction during transportation and use. According to the statistical data of China, the direct economic loss of steel pipe corrosion in China is more than 280 billion dollars each year, and the current global loss due to steel pipe corrosion is as high as 500 billion dollars. The anti-corrosion steel pipe can effectively prevent or slow down the corrosion, prolong the service life of the steel pipe, and reduce the operation cost of the steel pipe.
