HDPE structure wall hot-rolled pipe
The manufacturing process of the Kra pipe is quite unique and can be regarded as a high-tech "3D printing" process:
Extruding "printing materials": Heat and melt the HDPE raw materials, then extrude flat sheet materials and U-shaped sheet materials.
Spiral "printing" molding: On the steel mold, these heat-resistant material strips with a temperature of up to 190℃ are spirally wound at the predetermined positions.
Embedding "reinforcement bars": During the winding process, PP or PE corrugated pipes are synchronously embedded as supporting structures. This is like adding "bones and tendons" to the pipeline, significantly enhancing its compressive strength.
Cooling and shaping: Finally, the pipe material naturally cools and solidifies during rotation, achieving a single-step molding process.
Where is it mainly used?
Thanks to these advantages, the application scope of the Kra pipe is extremely broad, especially in the following fields:
Municipal engineering: Urban rainwater and sewage collection and discharge - this is its main application scenario.
Large-scale water conservancy: irrigation of farmland, long-distance water transfer, etc.
Industrial sector: Sewage pipelines in places such as chemical plants and power plants.
Transportation facilities: Drainage systems for highways and railways.
Port terminal: Drainage for port construction projects.
Key Technical Advantages
It adopts the socket-type electric fusion connection technology. During the pipeline connection process, the built-in electric fusion wire is energized and melts, allowing the pipes to integrate seamlessly. This truly achieves 100% no leakage at the interface and effectively protects the underground water source.
The unique structural design enables its ring stiffness to reach up to 32kN/m², which can withstand extremely high soil pressure and ground loads.
The pipe material itself has excellent flexibility and can well adapt to the uneven settlement of the foundation. It can also minimize damage to the greatest extent during geological disasters such as earthquakes.
HDPE material is resistant to corrosion and aging, and can ensure safe use for over 50 years under normal operating conditions..
The inner wall of the pipe is extremely smooth, resulting in low water resistance and no easy formation of scale. Therefore, the flow rate is fast and the volume is large, and the drainage capacity is extremely excellent.
