As a leading manufacturer with over a decade of expertise, Qingdao Yongke Machinery Co., Ltd. proudly presents our advanced HDPE Structured Wall Spiral Pipe Extrusion Line, engineered specifically for the demanding production of marine seawater intake and outfall pipes. Operating from our 10,000-30,000 square meter facility, we integrate precision German Krah technology with robust Chinese manufacturing to deliver a production line that ensures superior pipe quality, operational efficiency, and long-term reliability for critical underwater infrastructure projects worldwide. This line is the cornerstone for producing pipes that must withstand harsh marine environments, offering our clients a competitive edge in the water management and offshore industries.
Our extrusion line is designed to produce high-density polyethylene (HDPE) pipes with a structured wall profile, which is essential for applications requiring high ring stiffness, excellent hydraulic performance, and exceptional resistance to corrosion and abrasion. The core of the system is based on the proven Krah winding process, which creates a seamless, spirally wound pipe with a smooth interior and a corrugated exterior for added strength. This design is ideal for large-diameter pipes used in seawater intake for cooling systems, desalination plants, and wastewater outfalls, where integrity and longevity are non-negotiable.
Key Technical Features and Advantages:
High-Efficiency Extrusion: Equipped with a high-precision, energy-saving single or twin-screw extruder that ensures consistent melting and homogenization of HDPE raw material, resulting in pipes with uniform wall thickness and superior mechanical properties.
Intelligent Spiral Winding & Calibration: The heart of the Krah machine features a computer-controlled winding head that precisely layers the molten HDPE strip to form the pipe wall. An integrated vacuum calibration system instantly cools and shapes the pipe, guaranteeing precise dimensions and excellent ovality.
Automated Production Control: A centralized PLC with a user-friendly touch-screen HMI allows for full automation of the production process. Operators can easily set and monitor parameters like winding speed, temperature profiles, and pipe diameter, ensuring repeatable quality and reducing manual error.
Robust Construction for Marine-Grade Pipes: The line is built to manufacture pipes that meet the stringent requirements for marine applications, including resistance to saltwater corrosion, biological fouling, and high external pressure from soil and water loads.
Flexibility in Production: The line can be configured to produce a wide range of pipe diameters and wall structures (single-wall, double-wall corrugated) by simply changing the winding mandrel and extrusion die, offering great versatility for different project specifications.
Energy and Cost Savings: The frequency conversion drives on all major motors significantly reduce power consumption. The efficient use of raw material in the spiral winding process minimizes waste, lowering overall production costs for our clients.

Frequently Asked Questions (FAQ)
Q: What is the main advantage of the Krah winding process for marine pipes?
A: The Krah process creates a seamless, spirally wound pipe with a structured wall. This design provides exceptional ring stiffness and resistance to external loads (like soil and water pressure) while maintaining a smooth inner surface for optimal flow. It's ideal for the high-stress, corrosive marine environment.Q: Can this line produce pipes for other applications besides marine intake/outfall?
A: Absolutely. While optimized for marine-grade pipes, this versatile line can also produce structured wall pipes for municipal drainage, sewage conveyance, industrial effluent, and land-based culverts by adjusting material grades and production parameters.Q: What is the lead time for delivery and installation?
A: The standard lead time is typically 60-90 days after order confirmation, depending on the configuration and current production schedule. We provide detailed installation manuals and can dispatch engineers for on-site commissioning and training upon request.Q: Do you provide raw material specifications or sourcing guidance?
A: Yes, we offer detailed technical guidelines for the HDPE raw material (recommending grades like PE100) to ensure optimal performance. We can also suggest reliable material suppliers if needed.Q: How is the machine's energy consumption?
A: The line is designed with energy efficiency in mind. Key components like the extruder drive and cooling pumps use frequency conversion technology, which can reduce energy consumption significantly compared to traditional fixed-speed drives.Q: What kind of after-sales service and warranty do you offer?
A: We provide a standard 12-month warranty for the main machinery. Our service includes remote technical support via video call, a supply of essential spare parts, and the option for engineer visits. Comprehensive operation and maintenance manuals are provided.Q: Is the control system easy to operate for new technicians?
A: Yes. The PLC-based control system features an intuitive multilingual touch-screen interface. We provide thorough training for your operators on programming, monitoring, and troubleshooting the system.Q: Can the line be customized for a specific pipe diameter outside your standard range?
A> Yes, customization is a key service. We can engineer and manufacture the winding mandrel, dies, and calibrator to suit your required pipe diameter and wall structure profile. Please share your detailed specifications for a tailored quotation.
