Precision Welded Pipe Mill Line is specially designed to produce the industrial stainless pipe and titanium pipe, which can be widely applied in aviation, aerospace, nuclear power, power stations, oil refining, seawater desalination and other high-end pipe making field. Great Wall brings the advanced technology from Japan and hammer out one perfect manufacturing process and layout rational for forming, sizing, lubricating, welding, heat treatment, cooling, cleaning to make up defects of the original making titanium pipe in working process, which reduces distortion and scratching of the pipes. This production line needs high manufacturing and assembly precision. So we adopt high precision numerical control machine to process all the mechanical parts of the pipe mill. The forming & sizing machine is designed with the function of fast change roller & stand and adjustment by screen show, the line utilizes Siemens PLC control System, which has improved a lot the good productive rate and makes the line run steadily.
