Seamless steel pipe and seamless pipe distinction there are several common market, longitudinally welded pipes, spiral welded pipe and seamless steel pipe inner pipe Sichuan, but the Longitudinal and spiral welded pipe are very good identification, seamless of welded and seamless difference. From several aspects: First, the pipe is cut to length in general, and are generally 6 meters, nine meters or 12 meters. Seamless steel pipe length is very small, because the factory length increases very much. The second from a cross section of the tube head to see if there is rust, then put him clean, look closely, you will find the weld zone. Third, if the pickling it, then the most obvious. Shandong Liaocheng Polygram Pipe Manufacturing Co. is in production, sales, logistics in one large seamless steel pipe manufacturing enterprise, sales Baotou Seamless Steel Tube Plant, Chengdu Seamless Steel Tube Plant, Baoshan Iron and Steel Seamless Steel Tube Plant, Anshan seamless steel pipe a variety of plants, smelting steel seamless steel pipe plant, Wuxi Seamless Steel Tube Plant, Tianjin Seamless Steel Tube Plant and other major steel production of seamless pipe.
