As a leading manufacturer with over a decade of expertise, Qingdao Yongke Machinery Co., Ltd. specializes in providing high-performance Krah Pipe Production Lines. Our Plastic PE Pipe Extrusion Lines are engineered to deliver reliable, continuous production of high-quality profile wall pipes essential for modern infrastructure projects worldwide. We understand the critical demands of the pipe manufacturing industry, which is why our lines are designed for efficiency, durability, and consistent output, helping our clients secure a competitive edge in markets ranging from North America to Southeast Asia and beyond.
The core of our offering is a fully integrated extrusion line that transforms raw polyethylene into robust Krah pipes. The process is seamless and highly automated, ensuring minimal manual intervention and maximum productivity. Key advantages of choosing our production line include:
- Optimized Extrusion: Precision screw and barrel design ensures stable melting and homogeneous material flow, critical for consistent pipe wall structure.
- Advanced Calibration & Cooling: A multi-stage vacuum calibration tank and efficient cooling system guarantee precise pipe dimensions and excellent surface finish.
- Intelligent Control: A centralized PLC control system with a user-friendly HMI allows for precise parameter setting, real-time monitoring, and fault diagnosis, simplifying operation and maintenance.
- Robust Haul-Off & Cutting: A servo-driven haul-off unit provides stable traction, paired with an automatic cutting device for precise, clean cuts to the desired length.
- High Output & Low Energy Consumption: The line is engineered for high throughput while incorporating energy-saving technologies to reduce operational costs.
- Adaptability: The line configuration can be customized to produce pipes within a specific diameter range and for different application requirements.
Our Krah Pipe Production Line is built to handle the rigorous demands of producing pipes for potable water, gas distribution, sewerage, and drainage systems. The technical specifications highlight its capability and flexibility:
| Feature | Description |
|---|---|
| Extruder | Single or twin-screw extruder available, with optimized L/D ratio for PE processing. |
| Die Head | Spiral mandrel die designed for Krah profile wall pipe, ensuring uniform material distribution. |
| Calibration System | Multi-section vacuum calibration tank with precise temperature control. |
| Cooling System | Closed-loop spray or immersion cooling for efficient heat removal. |

Frequently Asked Questions (FAQ)
-
What is the main advantage of a Krah pipe profile wall structure?
The Krah profile wall design provides high ring stiffness and excellent strength-to-weight ratio, making the pipes ideal for deep burial and heavy-load applications while using less material compared to solid wall pipes. -
Can this production line process recycled PE material?
Yes, the line can be configured to handle a certain percentage of recycled PE granules. The exact ratio and necessary pre-treatment (like drying) depend on the material quality and desired final product specifications. -
What is the typical lead time for a complete production line?
Lead times vary based on the specific configuration and customization. Generally, standard lines have a lead time of several months from order confirmation to shipment. A detailed schedule is provided upon project finalization. -
Do you provide installation and commissioning services on-site?
Yes, we offer professional installation supervision, commissioning, and operator training services at the customer's factory. This ensures the line is set up correctly and your team is fully capable of operating it efficiently. -
How is the production speed or output of the line measured?
Output is typically measured in kilograms per hour or meters per hour. It depends heavily on the pipe diameter, wall thickness, and the specific PE material grade being used. We provide expected output ranges during the quotation process. -
What kind of after-sales support do you offer?
Our support includes a standard warranty period, ready supply of spare parts, remote technical assistance via phone or video, and the availability of service engineers for on-site troubleshooting if required. -
Can the line be upgraded to produce different types of plastic pipes in the future?
The modular design allows for certain upgrades, such as changing the die head or calibrator. However, significant changes (e.g., switching to a different polymer like PVC) may require more extensive modifications. Discuss your long-term plans with our engineers during the initial design phase. -
What are the key power requirements for operating the line?
The line requires a stable three-phase electrical supply. The total connected power depends on the extruder size and configuration, typically ranging from several hundred kilowatts. Detailed electrical specifications are provided with the technical documentation.
