Spiral Seam Large Diameter Welded Pipes
Product Description:
Our spiral seam welded pipes are made by rolling low carbon carbon structural steel or low alloy structural steel strip into tube blanks at a specific helix angle, called the forming angle. The pipe seams are then carefully welded to create a durable and reliable product. One of the distinguishing features of our spiral seam welded pipe is its ability to be manufactured from relatively narrow strips of steel to produce large diameter welded pipes.
These large diameter welded pipes have a wide range of applications, especially in sewer line. Our spiral seam welded pipe offers superior strength and corrosion resistance, making it ideal for sewer systems that require a long-lasting, efficient solution. Whether it's municipal wastewater discharge or industrial wastewater management, our pipes provide the necessary structural support and durability.
