Frequently Asked Questions
Q1: What types of pipes can be produced using this line?
A: The line is designed for Krah-type spiral-wound pipes, commonly used for large-diameter water supply, sewage, drainage, and industrial pipelines. Compatible materials include HDPE, PP, and PVC.
Q2: Are the stainless steel components replaceable?
A: Yes, all stainless steel parts (screw, barrel, die, cooling tank) are designed for easy replacement. We also offer spare parts kits to minimize downtime.
Q3: What is the typical lead time for delivery?
A: Depending on customization, lead time ranges from 45 to 60 days after confirmation of order. We can expedite for standard configurations.
Q4: Do you provide installation and training?
A: Yes, our engineers can supervise installation and provide onsite training for your operators. Remote support is also available.
Q5: What is the warranty period?
A: We offer a 12-month warranty on the entire production line, covering manufacturing defects. Extended warranty options are negotiable.
Q6: Can the line produce pipes with diameters smaller than DN200?
A: Our standard design starts at DN200. For smaller diameters, we recommend using a different extrusion line, but we can discuss modifications with our engineering team.
Q7: How is the pipe wall thickness controlled?
A: The PLC system automatically adjusts extrusion speed and haul-off rate to maintain consistent wall thickness. Manual adjustments can be made via the touchscreen.
Q8: What certifications does your production line have?
A: Our company holds ISO9001, ISO14000, and OHSAS18001. The production line itself complies with relevant CE standards (CE certification available upon request).
