The ERW pipe mill is used to process the strip thickness ¦Ä=3-12.7mm, the plate width B=430-1020mm, the steel grade X70, N80 (Max) strip winding, leveling, forming, welding and other processes into diameter ¦Õ139.7-¦Õ323.9mm straight seam welded pipe. It is equipped with medium frequency annealing, ultrasonic flaw detection, trimming flat head and hydraulic pressure test to produce welded pipes that meet API-5L, API-5CT, ASTM A500, JIS G3444 and other related standards. The electronic control system adopts Siemens PLC automatic control system, digital display system, Delta's variable frequency speed control system and so on. Simple operation, convenient maintenance and high reliability.
