Frequently Asked Questions (FAQ):
Q1: What raw materials can be used with this machine?
A: The machine is designed for HDPE (high-density polyethylene) granules or strips. Recycled HDPE is also acceptable if properly processed and blended.
Q2: How long does it take to install and commission the line?
A: Typically 15–20 working days under the guidance of our engineers. We provide detailed installation manuals and remote assistance.
Q3: Can the machine produce pipes with different wall thicknesses?
A: Yes, the wall thickness can be adjusted by changing the winding speed and extrusion parameters. A range of 10–100 mm is achievable.
Q4: What is the power consumption per ton of pipe produced?
A: Approx. 350–500 kWh per ton, depending on pipe size and material quality. Our energy-saving design helps reduce costs.
Q5: Does the machine include a quality control system?
A: Yes, we offer optional ultrasonic wall thickness measurement and pressure testing equipment for inline inspection.
Q6: What after-sales support do you provide?
A: We provide 12-month warranty on main components, free spare parts kit, and lifetime technical support via email/phone.
Q7: Can the machine produce pipes with integrated bell ends?
A: For spiral wound pipes, bell ends are usually formed by post-processing. We can recommend complementary belling machines.
Q8: How do you ensure the machine meets safety standards?
A: Our machines comply with CE safety requirements (CE certification optional). Emergency stop buttons, guards, and overload protection are standard.
