Product Detail

Product Tags

Our spiral welded carbon steel pipes are made by rolling low-carbon carbon structural steel into a pipe blank at a specific spiral angle, and then welding the pipe seams. This process allows us to produce large diameter steel pipes, which is very beneficial to various industries. By utilizing narrow steel strips, we can create pipes with superior strength and durability.
