QTech-Machinery supplied a complete Φ20–Φ110 mm HDPE pipe extrusion line for a customer producing PE water supply pipes. The project was developed for stable medium-capacity production, precise pipe dimension control, and flexible finished pipe handling.
The customer required a production line capable of processing PE100 HDPE material and producing black HDPE pipes with color identification stripes. To meet this requirement, QTech-Machinery designed a full production system covering raw material feeding, drying, extrusion, co-extrusion, pipe forming, vacuum sizing, spray cooling, servo traction, cutting, winding, stacking, and spare parts support.
As an experienced HDPE pipe extrusion line manufacturer in China, QTech-Machinery provided a turnkey solution based on the customer’s pipe diameter range, output target, material type, pipe application, and factory operation needs.
The final line was configured for Φ20 mm to Φ110 mm HDPE pipe production, with a designed output of 200–250 kg/h and a line speed range of 1–25 m/min, depending on pipe diameter and wall thickness.
The customer wanted to build a practical and efficient HDPE pipe production line for small and medium diameter PE water pipes. The machine needed to support continuous production, stable pipe quality, and convenient operation by local workers.
The main project requirements included:
1. Produce HDPE pipes from Φ20 mm to Φ110 mm
2. Use PE100 grade raw material
3. Produce black pipes with four color marking stripes
4. Reach a production capacity of around 200–250 kg/h
5. Maintain stable pipe outer diameter and wall thickness
6. Support both coiled pipe and straight pipe collection
7. Reduce manual operation during material feeding and production
8. Use reliable electrical control components
9. Provide accurate haul-off and cutting performance
10. Include spare parts and technical support for long-term operation
The customer also expected the supplier to provide a complete solution instead of separate machines. Therefore, QTech-Machinery prepared the full line layout, technical configuration, auxiliary equipment, control system, and downstream matching solution.
After evaluating the customer’s pipe size range, raw material, production capacity, and finished product handling requirements, QTech-Machinery recommended a complete Φ20–Φ110 mm HDPE pipe extrusion machine line.
The solution was built around an SJ75/33 single-screw extruder, supported by automatic vacuum loading, hopper drying, gravimetric dosing, color stripe co-extrusion, high-speed PE pipe die tooling, vacuum calibration, spray cooling, servo haul-off, combined cutting, pipe winding, and discharge stacking.
This design helped the customer achieve:
1. Stable extrusion output
2. Better raw material control
3. Accurate pipe forming
4. Consistent cooling performance
5. Smooth pipe traction
6. Flexible cutting methods
7. Easy switching between pipe winding and stacking
8. Higher production reliability
QTech-Machinery also considered the customer’s daily operation and maintenance needs. The line was equipped with a centralized control system, durable machine structure, stainless steel water-contact parts, and a complete spare parts package.
