The welding part of the roll bending pipes is straight seam. The SAW(Submerged ARC Welding) method is applied, in which welding is done by ARC, occurred in between two poles between the base metal and the welding part. This makes the production of strong, large diameter, high grade pipes possible. The demand for roll bending pipes has particularly increased in petroleum and gas line pipes. Outside diameterR/B I : 26-96"R/B II : 22-82" Thickness : 6.0-30.0mm Length : 6.0-12.0m Production capacity : 65,000 t/year
