The screw of the extruder of the PE pipe production line uses a barrier structure, and the barrel has a unique grooved structure in order to achieve good plasticization and mixing effects. HDPE (PP, ABS) large-caliber pipes use the special design of the basket mold to reduce the dissolution temperature and the host pressure to achieve a good mixing effect, thereby ensuring the output.
The unique design of the cooling and sizing system, using water circulation to cool HDPE (PP, ABS) raw materials, are suitable for the cooling of the above raw materials. The unique design can improve the stability and roundness of the diameter and meet the needs of thick-walled pipe production.
The special design of the vacuum sizing box can ensure the stability of the diameter and roundness, and the speed control system makes the traction speed stable. The entire production line can be controlled by PLC and LCD screen control panel for easy operation. It can be equipped with color-coded extruder, so that the produced pipes have color-coded lines.
High-quality ppr pipe production equipment is dedicated to the production of PPR pipe. It uses an efficient single screw extruder and is equipped with a Siemens brand PLC automatic control system to achieve high output and extrusion stability. At the same time, PE-RT, PEX, and PB pipe lines can be manufactured by changing the configuration unit. 可以采用单管生产线也可双管生产线，适用性强。 High-quality ppr pipe production equipment can adopt single pipe production line or double pipe production line, which has strong applicability. Can meet a variety of material resin production requirements.

过程中遇到问题如何解决 How to solve problems encountered during the production of high quality ppr pipe production equipment
1. The possible cause of scorch on the surface of the pipe is that the temperature of the fuselage or the machine head is too high; the machine head and the filter are not cleaned; there are impurities in the pellets; the thermal stability of the raw material is too low or the thermal stability dose is too small;
2. There may be black streaks on the surface of the pipe. The head temperature is too high and the filter is not cleaned.
3. The matte surface of the pipe may be the die temperature is too low or too high.
4, wrinkles on the surface of the pipe may be uneven temperature around the die; cooling water is too hot; traction is too slow.
5. The rough inner wall of the pipe may be that the core rod temperature is too low; the body temperature is too low; the screw temperature is too high.
6. Cracks in the inner wall of the pipe may be due to impurities; the core rod temperature is too low; the body temperature is low; the traction speed is too fast.
7. The inner wall of the tube has unevenness. The screw temperature may be too high; the screw speed is too fast.
8. There may be air bubbles in the inner wall of the tube.
Tips: In order to avoid purchasing risks, it is recommended that you confirm the supplier's qualification and product quality before purchasing the product.
