SSAW Welded Pipe Producing
1. Uncoil plate detection: Uncoil the steel plate and then enter the production line, and first conduct full plate ultrasonic inspection.
2. Flattening and milling: Use the anvil press to make the previously rolled steel plate neat, and then use the milling machine to double-sided mill the two edges of the steel plate to meet the required plate width, plate edge flatness and groove shape.
3. Cutting and forming: On the production line, spirally roll the steel plate along the outer edge into a tube shape.
4. Butt welding and cutting: Use advanced two-sided arc welding technology for pre-welding, internal welding, and external welding. The welded steel pipe is cut into standard lengths using a plasma ruler.
