High precise control system of pipe weight per meter is applied in this PPR Pipe Production line. It is used for measuring & calculating and precise control of pipe weight per meter and its extrusion output, to realize the constancy of pipe weight and line running according to set parameters. The application of this system can shorten the start-up time and improve the produced pipe quality, and save raw material. Welcome to visit our official website : http://www.pvcpipeextrusionline.com
