JCOE Pipe (OD 16''~60'', 12.8 meters per section)

This is large diameter longitudinal submerged arc welded (SAWL) pipe production line. The mill adopts progressive bending process, featuring evenly distributed forming stress, high uniformity of dimension, infinite sizes variation and with wide product range. It is capable of producing pipes of much higher thicknesses. Our mill adopts continuous axis contorting J-C-O forming process with characteristics of high forming accuracy and efficiency as well as balanced distribution of forming stress. The mill has the advantages of wide specifications and can produce pipes in any size within its production range.
