Spiral submerged arc pipe is a spiral seam metal pipe welded by submerged arc welding process. This innovative welding technology guarantees superior strength and durability, making our pipes ideally suited for demanding oil pipeline applications.
One of the significant advantages of our welded pipe is the ability to produce larger diameters from narrower billets. This allows us to manufacture pipes of various diameters from blanks of the same width. The production process is simplified, reducing costs and increasing efficiency. In particular, large diameter pipes can be easily produced using the spiral seam submerged arc welding process.
