Problems solved by technology

[0002] At present, PE anti-corrosion coatings are generally used in the anti-corrosion coatings applied to pipelines. However, when used to transport media with high temperature or use in areas with high temperatures, the anti-corrosion coatings in transmission pipelines do not exist for a long time, resulting in Corrosion of the pipeline has seriously affected and restricted the normal use of the pipeline, bringing potential waste to the national economy
