产品介绍：
Product Introduction: The flexible permeable pipe is made by processing PVC-coated steel wire into a spiral shape as the framework and winding hot-rolled fabric around the framework. It features all-round filtration throughout the entire body and rapid and effective drainage of groundwater. It has a high permeability rate and large drainage capacity, replacing the traditional polyvinyl chloride perforated pipe for water seepage.
Product specifications: Classified by hole diameter :50mm, 80mm, 100mm, 150mm, 200mm, 250mm, 300mm.
Product features: Small pore diameter, all-round water permeability, and good permeability; High compressive and tensile strength, long service life; Good corrosion resistance and resistance to microbial erosion; The overall continuity is good, with few joints and convenient connection. It has the advantages of soft texture and good adhesion to soil.

1. Materials for flexible permeable pipes
1. High-carbon steel wire: Anti-rust treatment is carried out with phosphoric acid and polyvinyl chloride to prevent acid and alkali corrosion. The unique steel wire spiral skeleton ensures that the pipe wall surface is flat and pressure-resistant.
2. Non-woven fabric filter layer: Ensures effective filtration and prevents sediment from entering the pipe.
3. Synthetic polyester fibers: The warp yarns are made of high-strength Teflon or nylon yarns coated with PVC, while the weft yarns use special fibers with sufficient tensile strength.
2. Flexible permeable pipes have the following characteristics:
1. Small aperture, all-round transparency, and good permeability;
2. High compressive and tensile strength, long service life;
3. Good corrosion resistance and antimicrobial properties;
4. Good overall continuity, few joints, and easy connection;
5. It has the advantages of soft texture and good combination with soil.
