As a leading manufacturer with over a decade of expertise, Qingdao Yongke Machinery is proud to introduce our advanced High-Efficiency Krah Helical Extrusion Pipe Production Line. Engineered for optimal performance and sustainability, this line represents a significant leap in manufacturing large-diameter plastic pipes. Our commitment to innovation and quality, backed by ISO9001, ISO14000, and OHSAS18001 certifications, ensures that this production line delivers exceptional value by maximizing output while minimizing energy consumption and operational costs for our global clientele.
Core Technology & Process Advantages:
This production line utilizes the proven helical winding extrusion (Krah) principle, which is renowned for producing high-strength, large-diameter pipes with remarkable efficiency.
- Superior Structural Integrity: The continuous helical winding process creates a monolithic pipe structure with excellent hoop strength and resistance to external loads, making it ideal for deep burial and heavy-duty applications.
- Material Efficiency: The system allows for precise control over wall thickness and material distribution, reducing raw material waste compared to other extrusion methods.
- Adaptable Production: The line can be quickly adjusted to produce pipes of varying diameters and lengths, offering tremendous flexibility for manufacturers serving diverse project requirements.
Energy-Saving & Operational Features:
A core focus in the design of this line is operational economy and reduced environmental impact.
- High-Efficiency Drive System: Equipped with premium AC variable frequency drives and motors that adjust power output in real-time to match the production load, cutting energy use significantly.
- Intelligent Thermal Management: The extruder barrel features optimized heating zones and advanced insulation to minimize heat loss. The integrated cooling system operates on a closed-loop principle where possible, conserving water.
- Automated Control: A centralized PLC with a user-friendly touchscreen interface allows for precise monitoring and control of all parameters—temperature, speed, tension—ensuring consistent quality and reducing manual intervention.
