1.HDPE pipe manufacturing line with the help of polymer forming and processing technology, heated molten material is extruded from the die through the main extruder and then formed into a round tube by vacuum sizing, then the cooled tube is fully formed and passed through the main extruder and extruded from the die through the main extruder.
2.The square tube is guided to the sewing machine and the hot melt adhesive is produced by a smaller size extruder. A spiral winding motion of the extruded square tube can be produced by forming rolls on the forming machine and forming an angle with the axis of the formed tube.
3.The die head layer of the molten adhesive extruder is extruded through the nozzle into the gap between two adjacent square tubes as the die head layer is extruded through the nozzle into the sides of the two adjacent square tubes.
4.The forming machine has an attached spray system. Cooled and placed in a dry place. Curing design. In this way, the hollow square tubes are wound continuously along the p-angle direction, bonded, cooled, cured and advanced to form the inner diameter of the HDPE large diameter hollow wound tubes.
