New Carbon Fiber Pipe Line Boosts Industrial Durability

In demanding industrial environments, pipeline reliability is mission-critical. Wear and tear or fractures can lead not only to production halts but also to significant economic losses and safety hazards. A new generation of pipe materials combining exceptional mechanical properties with durability and efficient production processes is now emerging.

Traditional plastic pipes, while widely used in certain applications, often fall short when facing extreme conditions like high temperatures, intense pressure, strong corrosion, or heavy impact loads. Polyethylene (PE) materials are known for excellent chemical resistance and flexibility, while carbon fiber boasts superior strength and rigidity. The fusion of these materials through advanced extrusion technology has given birth to PE-carbon fiber spiral pipes.

A high-quality PE-carbon fiber spiral pipe production line incorporates numerous precision engineering innovations:

The dimensional accuracy and surface quality of pipes largely depend on sizing and cooling processes. Specialized sizing and cooling methods precisely control pipe diameters (ranging from 40-300mm) while ensuring smooth interior and exterior surfaces. High-efficiency cooling systems with large-capacity water circulation rapidly stabilize pipe materials, reducing internal stress and enhancing overall performance.

During melt extrusion, the flow state of molten material is crucial. The production line features spiral-distributed fluid separation with spacious flow channels, ensuring sufficient residence time for uniform material distribution. This achieves perfect integration of carbon fiber with PE matrix, eliminating bubbles or structural defects while maintaining material homogeneity.

The 200-type carbon pipe production line employs low-melt temperature design, enabling extrusion molding at reduced temperatures. This approach not only lowers energy consumption but more importantly minimizes internal stress during cooling. Reduced internal stress translates to higher dimensional stability, extended service life, and decreased deformation risks.

The production line demonstrates remarkable flexibility, accommodating all polyolefin materials for coextrusion. Users can select different polyolefins based on application requirements, even producing two or three-layer spiral-reinforced pipes. This multilayer capability enables customized production with functional layers like wear-resistant or UV-protective coatings.

An optimized copper spiral sizing die incorporates pre-cooling and powerful vacuum adsorption at the inlet end. Pre-cooling stabilizes the melt before entering the sizing die, while strong vacuum adsorption prevents collapse or deformation during forming—particularly crucial for high-speed extrusion operations that ensure both productivity and quality.

Specially designed sprayers deliver intensive, uniform cooling across pipe surfaces, achieving rapid and consistent cooling that reinforces dimensional and structural stability. The combination of high-performance water pumps and specialized sprayers maximizes cooling effectiveness.

To accommodate various mold specifications and production needs, the equipment features a three-dimensional adjustment system driven by longitudinal movement motors. This enables comprehensive precision alignment of sizing dies and molds in all directions, significantly improving equipment versatility and operational convenience.

Stainless steel machine housings provide not only aesthetic appeal but also superior corrosion resistance and mechanical strength, ensuring long-term stable operation in harsh industrial environments.

Key production line parameters include:

• Extruder Models: SJ-90/30 (for larger pipes) and SJ-65/30 (for smaller pipes)
• Mold Diameter Range: 50-200mm (main line) and 25-100mm (optional)
• Sizing Tank Models: SG-200 (for 200mm molds) and SG-150 (for 150mm molds)
• Traction Machine Models: SQ-200 and SQ-150
• Winding Machine Models: SQ-200 and SQ-150
