This anti-corrosion coating is used in the early stages of project construction; it can overcome the shortcomings of petroleum asphalt coating technologies, resist bacterial attack on pipelines during actual transportation, and also possesses very high mechanical properties. Pipelines are also subject to erosion by chemicals and alkaline substances during transportation, but this coating technology can effectively resist the corrosion caused by such substances. At the same time, coal tar enamel also has good aging resistance and water absorption. The main drawback of this technology is its inability to resist the erosion of pipes caused by soil and high temperatures, and its cathodic protection performance also needs improvement.
