As a leading manufacturer with over a decade of experience, Qingdao Yongke Machinery is proud to introduce our advanced Krah Pipe Making Machine. Designed for high-efficiency production of large-diameter storm water drainage pipes, this PLC-controlled production line embodies our commitment to robust engineering and technological innovation. Serving global markets from North America to Southeast Asia, we understand the critical need for reliable infrastructure solutions. Our machine empowers manufacturers to produce superior quality corrugated pipes that meet the demanding requirements of municipal and industrial drainage projects, combining automated precision with exceptional output.
This integrated production line is engineered for stability and high throughput. The heart of the system is a precision extruder paired with a synchronized corrugator, ensuring consistent pipe wall formation. The entire process is managed by a centralized Programmable Logic Controller (PLC) with a user-friendly touch-screen interface, allowing for seamless operation, recipe management, and real-time monitoring of all critical parameters.
Key Features & Technical Advantages:
- Advanced PLC Control: Ensures precise synchronization between extrusion speed, corrugation, cooling, and haul-off. Operators can store and recall production parameters for different pipe specifications, minimizing setup time and human error.
- Large Diameter Capability: Specifically designed for manufacturing pipes with diameters ranging from 300mm up to 3000mm or larger, catering to major storm water and sewer main applications.
- High-Efficiency Corrugator: The corrugation module features a robust mold design and efficient cooling channels to produce pipes with excellent ring stiffness and structural integrity.
- Integrated Cutting System: An automatic cutting saw or cutter provides clean, burr-free cuts at programmed lengths, ensuring precise pipe segments ready for installation.
- Customizable Configuration: The line can be tailored with options such as double-wall corrugation heads, inline printing units, vacuum sizing tanks, and different haul-off types (caterpillar or belt) to match specific production goals.
Technical Specifications Overview:
| Parameter | Description / Typical Range |
| Pipe Diameter Range | 300mm - 3000mm (Customizable beyond) |
| Control System | PLC with Color Touch Screen HMI |

Frequently Asked Questions (FAQ)
-
Q: What is the main difference between this machine and standard pipe extrusion lines?
A: This line is specifically engineered for the Krah process, which is ideal for large-diameter, structurally strong corrugated pipes. It integrates a sophisticated corrugator that forms the pipe profile directly after extrusion, unlike lines for smooth-walled pipes. -
Q: Can this line produce both single-wall and double-wall corrugated pipes?
A: Yes, the base configuration is typically for single-wall pipes. For double-wall production, an additional extrusion unit and a specialized corrugation head can be integrated into the line as an available option. -
Q: What is the typical lead time for delivery and installation?
A: Lead time depends on the specific configuration and order queue. Generally, it ranges from 60 to 120 days after contract finalization. We provide detailed installation guidance and can arrange technician support. -
Q: What kind of after-sales service and support do you offer?
A: We offer comprehensive support including installation supervision, operator training, a warranty period, and lifelong technical consultation. Critical spare parts are available for supply to ensure minimal downtime. -
Q: How energy-efficient is this production line?
A: The line utilizes modern servo drives and high-efficiency extruders designed to optimize power consumption. Specific energy usage data can be provided based on your targeted pipe specifications and production rate. -
Q: Is the control system easy to operate for new technicians?
A: Absolutely. The PLC-based system features an intuitive touch-screen interface with multilingual support. We conduct thorough training to ensure your team can confidently operate and perform basic troubleshooting. -
Q: Can we use recycled plastic material with this machine?
A: The machine can process certain grades of recycled HDPE or PP, often in a blended form with virgin material. We recommend discussing your specific material formula so we can advise on any necessary machine adjustments. -
Q: Do you provide assistance with factory layout and utility requirements?
A: Yes, upon order confirmation, we provide detailed foundation drawings, utility requirements (power, water, compressed air), and can advise on optimal workshop layout for the production line.
