Production process of porous plastic tube
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.
Advantages of porous plastic tube
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.
Application of porous plastic tube
| 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.
Frequently Asked Questions (FAQ)
What materials are typically used to manufacture porous plastic tubes?
Porous plastic tubes are primarily made from high-quality polymers such as PVC-U, HDPE, and PP, which ensure excellent structural integrity and environmental resistance.
How long do porous plastic tubes last in underground installations?
These tubes are highly durable, with an estimated service life of 50 years or more. They are designed to resist aging, acids, alkalis, and harsh chemical environments.
Why are porous plastic tubes considered highly compression resistant?
Their unique honeycomb or grid structure distributes external pressure evenly. This design increases compressive strength by 10 to 100 times compared to standard plastic pipes, allowing them to replace steel pipes in road crossings.
How does using these tubes save construction time and costs?
The integrated design of the sheath and sub-pipe eliminates the need for secondary threading, reducing construction time by up to 30%. Furthermore, the overall material and installation cost is 20% lower than PE pipes and 50% lower than steel pipes.
What are the primary fields of application for porous plastic tubes?
They are widely applied in telecommunication projects for fiber optic routing, municipal drainage systems, underground utility corridors, agricultural water-saving irrigation, and high-voltage electrical cable insulation.
