ERW/HFW steel pipe
Overview
ERW pipeline is an abbreviation for resistance welded steel pipe, while HFW pipeline represents high-frequency welded steel pipe. The pipeline is made of steel coils, and the welds are parallel to the pipeline. It is one of the most commonly used tools in agricultural, industrial, and construction activities. The manufacturing process of ERW steel pipes includes HFW. ERW welding includes low, medium, and high-frequency welding, while HFW is particularly suitable for high-frequency resistance welding.
Product characteristics
Compared to other forms of welded pipes, ERW pipes have greater strength
Better performance than ordinary welded pipes, lower cost than seamless steel pipes
The production process of ERW welded pipes is far safer than other welded pipes.
