Spiral welded pipes, as the name suggests, are steel pipes produced in spiral form by sewing completely by submerged arc welding method. The rolls are straightened into strips and directed to the reels to be brought into the desired form. Roll band edges bent at a predetermined angle according to the pipe diameter are optimally combined for welding.
Internal and external resources are constantly controlled throughout the production line. The welding places of the sheet metal, which is first internally and then externally joined by the submerged arc welding method, are 100% controlled by an automatic ultrasonic control system. After the roll band is in the form of a pipe, it is cut in desired lengths with an automatic plasma machine.
