As a leading manufacturer specializing in advanced pipe production machinery since 2010, Qingdao Yongke Machinery Co., Ltd. is proud to present our Krah Pipe Extrusion Line. This fully automated HDPE spiral wound pipe production line represents the pinnacle of efficiency and reliability for manufacturers seeking to produce high-quality corrugated pipes for drainage, sewage, and culvert applications. Engineered with precision and built for continuous operation, our line integrates the proven Krah technology with our own innovations to deliver superior pipe structural integrity and production throughput.
Core Product Features & Technical Advantages:
- Fully Integrated Automation: From raw material feeding to final pipe cutting and stacking, the entire process is controlled by a centralized PLC system with a user-friendly touch screen interface, minimizing manual intervention and ensuring consistent product quality.
- Advanced Krah Extrusion & Winding Technology: The system utilizes a precision extrusion unit coupled with a computer-controlled spiral winding head. This technology creates a continuous, interlocked spiral profile, resulting in pipes with excellent ring stiffness, impact resistance, and long-term performance.
- High-Efficiency Extruder: Equipped with a robust, energy-saving extruder (single or twin screw options available) designed for optimal plasticizing and stable output of HDPE material, ensuring uniform pipe wall thickness and material properties.
- Precision Cooling & Calibration: A multi-stage cooling system, including water bath and air cooling, ensures controlled and gradual cooling of the extruded profile. This is critical for achieving dimensional stability, preventing deformation, and enhancing the final pipe's mechanical strength.
- Customizable Production Parameters: The line can be configured to produce a wide range of pipe diameters and wall thicknesses to meet specific project requirements. Production speed and other parameters are easily adjustable via the control panel.
- Durability & Low Maintenance: Constructed with high-grade components and a sturdy frame, the production line is designed for 24/7 operation in industrial environments, offering long service life and reduced downtime.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of the Krah method for spiral pipe production?
A: The Krah process creates a continuous, mechanically interlocked spiral profile. This results in pipes with superior structural strength, high ring stiffness, and excellent resistance to soil pressure and dynamic loads, making them ideal for deep burial and heavy-duty applications. -
Q: Is the production line suitable for materials other than HDPE?
A: The line is primarily optimized for HDPE. However, with specific configuration changes to the extruder and screw design, it may be adapted for other polyolefins like PP. Please consult our engineers for feasibility regarding your target material. -
Q: What level of training is provided for operating this automated line?
A: We provide on-site installation, commissioning, and comprehensive operational training for your key technicians. The training covers machine operation, routine maintenance, basic troubleshooting, and safety procedures. -
Q: How customizable is the pipe diameter and stiffness class (SN rating)?
A: The line is highly customizable. By changing the winding head molds, extrusion die, and adjusting process parameters, we can configure the machine to produce a wide range of diameters and wall thicknesses to achieve different SN stiffness ratings (e.g., SN4, SN8, SN16) as required. -
Q: What is the typical lead time for delivery and installation?
A: Lead time depends on the specific configuration and order schedule. Generally, it ranges from 60 to 90 days after contract confirmation. We ship from Qingdao port and can arrange expert engineers for overseas installation. -
Q: Does the line include auxiliary equipment like pipe cutters or stackers?
A: Yes, our fully automatic line is a complete solution. It typically includes an automatic cutting unit (saw or guillotine) and a stacking/conveying system to form a seamless production workflow from extrusion to finished product handling. -
Q: What kind of after-sales support do you offer?
A: We offer a standard warranty period, provide remote technical support via phone/email, and maintain a stock of commonly required spare parts. For major issues, our service engineers are available for on-site visits. -
Q: Can the control system interface support multiple languages?
A> Yes, the human-machine interface (HMI) of the PLC control system is often customizable and can support multiple language options, including English, to facilitate operation by international clients.
