LSAW Steel Pipe main production process:

1. Plate Ultrasonic Inspection. Each plate is first full-plate ultrasonic inspected after entering the process.
2. Plate Edge Milling. The Plate edges are milled by Edge Milling Machine to obtain the required width, parallelism and bevel angles.

3. Plate Edge Crimping. The two edges of the plate are crimped at the Crimping Machine to get the required radius.

4. Forming. The first half of the plate is fed step by step into the Pipe Forming Press to form the plate into a" J "shape. Then another half of the plate is pressed step by step to form the plate into" C "shape. The last stroke is to press the plate into an open "O" shape.
5. Pre-Welding. The two edges of the open seam pipe should be brought together by tack welding machine then welded by tack welder using metal active-gas arc welding (MAG) process.
6. Inside Welding. The pipe is welded from inside of the pipe by multi-pass tandem submerged-arc welding (max. four wires).

7. Outside Welding. The pipe is welded from outside of the pipe by multi-pass tandem submerged-arc welding.

8. Ultrasonic Testing and X-ray Inspection. The welded area on both sides of the weld is 100% tested by automatic ultrasonic tester.

9. Pipe Ends Beveling. All pipes qualified from previous testing are subject to pipe end processing to get the required bevel dimension. 

10. Coating. The qualified pipes are coated for anti-corrosion as per the requirements of customers. Such as 3LPE,Coal tar epoxy, bitumen etc.
