As a leading manufacturer in plastic pipe machinery since 2010, Qingdao Yongke Machinery Co., Ltd. is proud to introduce our advanced Krah Helical Extrusion Pipe Production Line. Engineered for demanding industrial applications, this production line integrates an innovative cooling system designed to deliver unparalleled consistency in large-diameter plastic pipe manufacturing. Our commitment, backed by ISO9001 certification for quality management, is to provide machinery that enhances your production efficiency and product reliability.
The core value of this line lies in its ability to produce high-integrity pipes with uniform wall thickness and superior dimensional stability, which are critical for infrastructure projects in sectors like drainage, irrigation, and industrial fluid transport. Operating from our 10,000-30,000 sqm facility in Qingdao, we combine robust engineering with precise process control to offer a solution trusted by clients across North America, Europe, Southeast Asia, and other global markets.
Key Features & Technical Advantages:
- Advanced Helical Extrusion Technology: Utilizes the Krah method, where extruded plastic profile is wound and fused to form large-diameter pipes. This process allows for significant material savings and the production of pipes with diameters far exceeding conventional extrusion limits.
-
Precision Cooling & Temperature Management: The integrated advanced cooling system is the heart of the line. It ensures controlled, gradual cooling of the welded seams and the pipe body, which is vital for:
- Eliminating internal stresses and warpage.
- Achieving consistent crystallinity and mechanical properties throughout the pipe.
- Enhancing the long-term pressure rating and service life of the final product.
- Automated Process Control: A centralized PLC system monitors and regulates key parameters such as extrusion speed, winding pitch, fusion temperature, and cooling rate. This automation minimizes human error and ensures batch-to-batch repeatability.
- High Output & Flexibility: The line is designed for continuous, high-volume production. It can be configured to produce pipes with a wide range of diameters and wall thicknesses, catering to various project specifications from municipal drainage to mining slurry transport.
- Durability & Low Maintenance: Constructed with high-grade components and featuring a user-friendly interface, the machinery is built for longevity in harsh industrial environments, reducing downtime and total cost of ownership.

Frequently Asked Questions (FAQ):
-
What is the main advantage of the Krah method over other large-diameter pipe production techniques?
The Krah helical extrusion method is highly efficient for producing very large diameter pipes (often over 2 meters) that would be difficult or impossible with conventional extrusion. It offers excellent material utilization and produces pipes with high structural ring stiffness, making them ideal for deep burial and high-load applications. -
How does the advanced cooling system contribute to pipe quality?
Proper cooling is critical to prevent warping, shrinkage, and internal stress in plastic pipes. Our multi-zone system provides gradual, controlled cooling, which ensures uniform crystallinity and mechanical properties. This results in pipes with consistent dimensions, improved long-term pressure resistance, and reduced risk of premature failure. -
Can this production line process recycled plastic materials?
Yes, the line can be configured to process high-quality recycled HDPE or PP granules, subject to material consistency and purity. We recommend discussing your specific raw material specifications with our engineering team to ensure optimal line configuration. -
What is the typical lead time for delivery and installation?
Lead time depends on the specific configuration and current production schedule. As a guideline, standard lines may have a lead time of several months. We provide detailed project timelines upon finalizing technical specifications and order confirmation. -
Do you provide training for our operators?
Absolutely. Comprehensive operator training is a standard part of our commissioning service. Our technicians will train your team on safe operation, routine maintenance, basic troubleshooting, and quality control procedures. -
What kind of after-sales support is available?
We offer remote technical support, online spare parts ordering, and can dispatch service engineers if required. Our support is designed to minimize your downtime and ensure the long-term productivity of your investment. -
Is the line customizable for different pipe specifications?
Yes, modular design is a key feature. We can tailor components like the extruder size, winding mandrel diameter, cooling tunnel length, and cutting system to match your target pipe dimensions (diameter, wall thickness, length) and production capacity requirements. -
What are the main power requirements for this production line?
Power requirements vary significantly based on the line's size and configuration. A typical line will require a substantial three-phase electrical supply. Detailed power consumption data is provided with the technical proposal for your specific project.
