COE mill produces high-frequency welded pipe, rectangular pipe, longitudinal submerged arc welded pipe, and stainless steel pipe. This technology is particularly effective for producing high-frequency welded pipe with larger thickness or longitudinal submerged arc welded pipe. The production line utilizes PCK's patented technology (Invention Patent Number: ZL20071003068.X) to achieve high production efficiency and stable product quality. The mill is equipped with LINSINGER's milling machine, EFD's 1500KW high-frequency welding system, and five 500-960kW medium-frequency heat treatment systems. These systems can perform annealing, normalizing, or quenching and tempering on the weld seam and HAZ of high-frequency welded pipe.
