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.
