It is one of the most basic methods for pipeline corrosion prevention to evenly and densely coat the derusted metal pipeline surface with paint to isolate it from various corrosive media. Since the 1970s, pipeline laying in polar, marine and other harsh environments, as well as oil heating and transportation, have raised the temperature of the pipeline, putting forward more requirements for coating performance. Therefore, more and more pipeline anti-corrosion coatings

With the rapid improvement of people's living standards, especially the change of urban residents' lifestyle, the pressure of urban underground pipelines is also increasing. The original pipe diameter becomes smaller due to long-term pipe sludge and rust solidification, which can not meet the stable flow of discharge flow. The sludge deposit at the bottom of the pipe always raises the downstream of the drainage pipe, resulting in a decrease in the slope of the pipe, a flat flow rate, pipe blockage and double discharge
