As a professional manufacturer with over a decade of expertise, Qingdao Yongke Machinery Co., Ltd is proud to present our advanced Large Diameter PVC Pipe Extrusion Line. Engineered specifically for demanding municipal pipeline projects, this production line represents our commitment to delivering robust, efficient, and reliable manufacturing solutions. Our ISO-certified factory ensures every component meets stringent quality standards, providing our global clients in North America, Europe, Asia, and beyond with equipment that builds the backbone of modern infrastructure. This line is designed to produce high-strength, corrosion-resistant PVC pipes essential for water supply, drainage, and sewage systems.
The core of this extrusion line is its high-performance, computer-controlled extruder, typically a conical twin-screw design for optimal PVC processing. It ensures stable melting, excellent mixing, and consistent output, which is critical for maintaining the uniform wall thickness and dimensional accuracy required for large-diameter pipes. The downstream equipment is synchronized for seamless operation.
- Precision Vacuum Sizing & Cooling: A multi-stage vacuum calibration tank with precise water temperature control ensures the pipe is perfectly sized and cooled from the inside out, preventing deformation and internal stresses, resulting in superior roundness and long-term performance.
- Robust Haul-Off and Cutting: The heavy-duty caterpillar haul-off unit provides powerful, slip-free traction. Coupled with an automatic traveling saw, it guarantees clean, square cuts with precise length control, minimizing material waste.
- Intelligent Control System: The entire line is managed by a centralized PLC with a user-friendly touchscreen HMI. Operators can monitor all parameters—temperature, speed, pressure—in real-time, enabling quick adjustments and ensuring consistent product quality.
- High Efficiency & Energy Saving: The line incorporates optimized screw designs and high-efficiency drives that reduce specific energy consumption. Optional automatic raw material handling systems further minimize labor and improve overall production efficiency.
- Durability for Continuous Operation: Built with high-grade components and a rigid frame, this line is designed for 24/7 operation in industrial environments, ensuring high uptime and a long service life with minimal maintenance.
For municipal project contractors and pipe manufacturers, this translates into the ability to produce pipes on-demand, reduce dependency on external suppliers, control quality from raw material to finished product, and ultimately improve project timelines and profitability.

Frequently Asked Questions (FAQ)
-
What is the maximum and minimum pipe diameter this line can produce?
The standard range is typically from 200mm to 1200mm in diameter. However, the line can be customized to produce pipes outside this range. The specific configuration of the extruder, die head, sizing sleeve, and cooling tank will be adjusted according to your target pipe dimensions. -
Can this line process recycled PVC material?
Yes, it can process a certain percentage of high-quality recycled PVC granules alongside virgin material. The exact ratio depends on the quality of the recyclate and the required final pipe specifications. We recommend consulting with our engineers to determine the optimal formulation and any necessary machine adjustments. -
What is the expected production output (meters per hour) for a DN800 pipe?
Output is measured in weight (kg/h) rather than length, as wall thickness varies. For a DN800 pipe with a standard SDR rating, the output could range from approximately 500 to 900 kg/h, depending on the extruder size and compound. We provide detailed output estimates based on your specific pipe design. -
Is training for our operators included?
Yes. We provide comprehensive operational and maintenance training at your factory after installation. This includes hands-on instruction on machine operation, parameter setting, routine maintenance, and basic troubleshooting to ensure your team can run the line efficiently and safely. -
How is the line shipped, and what is the lead time?
The line is typically shipped in standard 40-foot containers from Qingdao Port. The lead time for a standard configuration is generally 60-90 days after order confirmation, subject to the complexity of customization and current production schedule. -
What kind of after-sales support do you offer?
We offer remote online support, a comprehensive parts manual, and a supply of commonly used spare parts. For major issues, we can dispatch our service engineers to your site. The specific warranty period and support terms are detailed in our sales contract. -
Can the line be automated with robotic handling for the finished pipes?
Absolutely. We can integrate various automation solutions, such as automatic pipe handling, stacking, and bundling systems. These options help create a fully automated production cell, reducing manual labor and increasing overall line efficiency. -
What standards are the produced pipes compliant with?
The extrusion line is designed to produce pipes that can meet international standards such as ISO 4435 for buried drainage and sewerage, ASTM D3034 for pressure pipes, and various national standards. The final pipe compliance depends on using the correct raw material formulation and adhering to the proper operating procedures.
