Carbon Steel Pipe Anti-Corrosion Methods
First, lining anti-corrosion
Lining anticorrosion is to prevent the corrosion of the pipe wall by coating the inside of the pipe with chemically stable anticorrosive materials, such as fluorine plastic, polyester and so on. This method is suitable for pipelines conveying various chemical liquids, such as acid, alkali, etc., but the price is high, and the scope of application has certain limitations.
