Advanced Technology: Importing welder with TIG butt welding and roller type AL tube making and haul-off in and smooth welding seam, high productivity and beautiful product can be in compliance with American standard. Importing all tape jointer, layer after extrusion with two welding torches guarantee easily changed die and a long time continuous production process with high quality producer rate. High grade disposition: Key components of the line like reducer of main extruder, main welder, printer and contactor are all imported ones of world famous brand, which features high precision and reliable performance. High automation: The whole line takes advantage of PCC controlling system manufactured by B&R of Austria which provided a man-machine interaction center and two subordinate control panels and gives an automatic closed-loop control to the extrusion, haul-off, temperature and the diameter of pipe. Advanced and perftctideteetion system: Laser diameter scanner providing, through the PCC system, the outer diameter of inner PE tube and that of finished tube with an auto, closed-loop control. The eddy fault detector detects the welding seam and the jet printer can mark any welding fault on the finished tube automatically and correctly, which assures product high quality. Reliable: High grade disposition, constant design innovation, strict manufacture-turning procedure technology, perfect detection and quality guarantee system, first time service provided by specialist. Multi-function: The line can produce PE-AL-PE composite pipe as well as PEX and PPB pipes.
