ERW carbon steel pipe for structural applications
ERW Carbon Steel Pipe, also known as Electric Resistance Welded Carbon Steel Pipe, is a kind of highly efficient welded steel pipe. It is formed by rolling steel coils or steel strips into pipe blanks through a forming machine, heating both ends of the pipe blanks with high-frequency current and welding the edges under pressure. The manufacturing process of ERW carbon steel pipes is mature and the cost is low, so they are widely used in building structure engineering.The main...
