Crush and dry the raw materials such as PVC, PE or PP, control the moisture ≤ 0.5% to ensure the purity of the material.
Through the three-screw extruder heated to 220-250 ℃, pressure 10-20 MPa, through the die extrusion molding. The mold design determines the porosity (25%-30%) and wall thickness uniformity.
Adopt 20-30℃ water tank for rapid cooling to avoid deformation and ensure dimensional stability.
Precision cutting to standard length (6-8 meters), compression test, appearance inspection and size measurement.
Packed with moisture-proof and environmentally friendly materials, suitable for long-distance transportation.
The honeycomb/grid structure makes the compressive performance 10-100 times higher than ordinary plastic pipes, which can replace steel pipes crossing the road.
The integrated design of sheath and sub-pipe eliminates the need for secondary threading and saves 30% of the construction period; the bending radius is up to 4 meters, which is suitable for complex terrain.
The material can be recycled and the production energy consumption is low; the comprehensive cost is 20% lower than PE pipe and 50% lower than steel pipe.
Resistant to acid and alkali, aging, service life ≥50 years, suitable for coastal and chemical environments.
| Fields | Specific Scenarios |
|---|---|
| Communication Engineering | Fiber optic cable/cable casing, weak power pipe network (e.g. 24-hole trunk pipeline in Laoshan District, Qingdao City) |
| Municipal Construction | Drainage Systems, Comprehensive Underground Pipe Corridors (Excavation is only 10% of a concrete pipe) |
| Agricultural Irrigation | Water-saving seepage irrigation system, reduce water waste |
| Electric Power Engineering | High-voltage cable protection, excellent insulation performance |
| Construction | Underfloor Heating Pipes, Rainwater Harvesting Systems, Replacement of Concrete Pipes |
Porous plastic pipes have become the preferred material for modern infrastructure construction due to their modular design, cost-effectiveness and environmental friendliness. In the future, with the application of nano-coating technology and bio-based materials, its performance and market penetration will be further enhanced.
Porous plastic tubes are typically manufactured using high-quality thermoplastic materials such as PVC-U, HDPE (High-Density Polyethylene), and PP (Polypropylene) depending on the specific application requirements.
These tubes are designed for long-term infrastructure projects and have a service life of 50 years or more, offering excellent resistance to aging, corrosion, acids, and alkalis.
Yes. Thanks to their honeycomb or grid structure, their compressive performance is 10 to 100 times higher than ordinary plastic pipes, making them strong enough to replace traditional steel pipes for road crossings.
The integrated design of the sheath and sub-pipe eliminates the need for secondary threading, reducing the construction period by 30%. Economically, the comprehensive cost is 20% lower than PE pipes and 50% lower than steel pipes.
Porous plastic tubes are highly eco-friendly because the materials are fully recyclable, the production process consumes less energy, and they can be used in water-saving seepage irrigation systems to reduce water waste.
Yes, they support a bending radius of up to 4 meters, which allows them to easily navigate complex terrains and obstructions without requiring extra fittings.
