The PE pipe production line is mainly composed of seven parts: the pipe production line is composed of a control system, an extruder, a die head, a shaping cooling system, a tractor, a planetary cutting device and a turning frame. There are generally two extruders in each pipe production line. The main extruder adopts a strong conveying bush and a high-efficiency screw, and the other smaller extruder is used to extrude the marking line. There will be multiple composite pipes. extruder.

PE pipe production process: 1. Raw material + masterbatch → 2. Mixing → 3. Vacuum feeding → 4. Raw material drying → 5. Single screw extrusion → 6. Four-color line extrusion → 7. Basket or screw mold → 8. Sizing sleeve → 9. Spray vacuum setting box → 10. Ribbon printing machine → 11. Crawler tractor → 12. Planetary cutting machine → 13. Pipe stacking rack → 14. Finished product testing and packaging.

Adopt spiral die, which is designed for HDPE, PP large-diameter thick-walled pipes, low melt temperature, good mixing performance, low cavity pressure, stable production, and obvious advantages.

PLC programmatically controls the operation and time, and has a good human-machine interface. All process parameters can be set and displayed through the touch screen. It can be equipped with a special extruder for marking lines to produce pipes with color marking lines that meet the requirements of national standards. .

Vacuum sizing box, this kind of vacuum sizing box is specially designed and can control the vacuum degree in multiple stages, which can ensure the dimensional stability and roundness of HDPE and PP pipes. The extruder and tractor use imported speed governors to move and control, good stability, high precision and high reliability.

The sizing and cooling system of special technology adopts water film lubrication and water ring cooling, which meets the requirements of HDPE and PP materials and ensures the stability of diameter and roundness of high-speed production of thick-walled pipes.
