Adhesion Mechanisms in Polyethylene (PE) Pipe Coatings: Analysis of Key Factors and Performance Enhancement Strategies

Polyethylene (PE) is considered an ideal material for pipe coatings due to its favorable mechanical properties, high chemical resistance, and cost-effectiveness. PE coatings are widely used in oil, gas, and water supply industries to protect pipes against corrosive and abrasive elements. The effectiveness of these coatings largely depends on their adhesion to the pipe surface, as they serve as the primary defense barrier against corrosive environments. Optimal performance requires strong initial adhesion and long-term stability under various operational conditions. Given the high costs of coating replacement and the requirement for extended service life (minimum ۲۰ years) for buried pipes, proper coating selection and design are critically important. This article examines market share, adhesion mechanisms, influencing factors, and strategies for improving the performance of polyethylene coatings.
