Introduction to coating of ERW pipes
In modern industry, Electric Resistance Welded (ERW) pipes are indispensable as essential components in fluid transportation systems. Produced by heating the edges of steel strips and joining them under pressure via high-frequency resistance welding, ERW pipes are valued for their efficiency, cost-effectiveness, and wide applicability. Despite their inherent mechanical advantages, ERW pipes often face harsh service conditions. In such scenarios, uncoated pipes are prone to corrosion, abrasion, and degradation—issues that significantly reduce operational life and safety. Coating serves as a critical protective barrier, extending the pipe’s service life and enhancing its performance. This article provides an in-depth overview of ERW pipe coatings, including their necessity, benefits, types, and application considerations.
