JCOE Large Diameter LSAW Pipe Mill There are two production processes for LSAW pipe i.e., JCOE and RBE.
The advantages of JCOE production process are that it can produce more than 30mm thick steel pipe, which is suitable for the production of extra thick wall steel pipe; the disadvantages are low production efficiency (10 pieces / hour) and large investment. It is usually used for the production of straight seam submerged arc steel pipe with diameter range of 508 - 1422 mm, wall thickness of 8 - 40 mm and length of 10 - 12.5 m.
Production Process Plate Ultrasonic Flaw Detecting → Plate Edge Milling → Front Pre Bending →JCO Pipe Forming → Pre Welding → Pipe Internal Welding → Pipe External Welding → Weld Ultrasonic Flaw Detecting → Pipe Weld (X-Ray) Flaw Detecting → Pipe Expanding → Hydrostatic Testing → Pipe Pressure Straightening → Pipe Rounding → Pipe End Internal And External Weld Flattening → Pipe Chamfering → Pipe Ultrasonic Phased Array Detecting → Pipe Weld X-Ray Detecting → End X-Ray Photographing → Weighing And Length Measuring → Pipe Marking → Delivering
