【Abstract】 The types of external coating of buried steel pipelines and coatings’ application home and abroad are introduced. In the light of shortcomings of various coatings in practical use,a new coating material—100% solid polyurethane coating material ( 2K or DD type) is recommended to use. This kind of coating material has advantages in comprehensive properties, strong suitability, filming with one-time’s spraying, painting and casting,and formed coating covers from elastomer to rigidity with perfect properties in anti-corrosion and mechanical strength.更多还原
