What is ERW Pipe? A Technical Overview
High-Frequency Straight Seam Welded Pipe, commonly known as ERW pipe or ERW steel pipe, is a type of welded steel pipe manufactured through a specialized process. The ERW pipe welding process utilizes the skin effect and proximity effect of high-frequency current. This process locally heats the edges of the steel strip to a molten state, and then roller extrusion is applied to achieve intergranular bonding, forming the pipe.
