Product Description

RBE Large Diameter LSAW Pipe Mill
There are two production processes for LSAW pipe i.e., JCOE and RBE.
RBE production process has the advantages of high production efficiency (15 pieces / hour) and small investment; the disadvantage is that the maximum wall thickness is not more than 30mm. It is usually used for the production of straight seam submerged arc steel pipe with diameter of 508 - 1422 mm, thickness of 6 - 30 mm and length of 10 - 12.5 m.
Production Process
Plate Ultrasonic Flaw Detecting → Plate Edge Milling → RB Pipe Forming → Rear Pre Bending → Pre Welding → Internal Welding → External Welding → Weld Ultrasonic Flaw Detecting → Weld X-Ray Flaw Detecting → Pipe Expanding → Hydrostatic Testing → Pressure Straightening → Pipe Rounding → Pipe End Internal And External Weld Flattening → Chamfering → Pipe Ultrasonic Phased Array Detecting → Pipe Weld X-Ray Detecting → Pipe End X-Ray Photographing → Weighing And Length Measuring → Pipe Marking → Delivering
