Product Description


Api Erw Lsaw Welded Steel Line Pipe




Hebei Chengyuan Pipe Industry Group Co., Ltd.

The main production process of large diameter Straight Seam Steel Pipe is as follows:

1. Plate detection: When the steel plate used to manufacture large diameter submerged arc welded straight seam steel pipe enters the production line, the whole plate is first inspected by ultrasonic wave.

2. Milling edge: The two edges of the steel plate are milled by a milling machine to achieve the desired width, edge parallelism and groove shape.

3. Preflanging: pre bending machine is used to pre bend the edge of the plate, so that the edges of the board meet the required curvature.

4. Forming: On the JCO forming machine, the half of the pre-bent steel plate is stamped several times to form a "J" shape, and then the other half of the steel plate is equally bent to form a "C" shape, finally forming an open "O" shape.

5. Pre welding: make the formed longitudinal welded steel pipe seams and use gas shield welding (MAG) for continuous welding.
