Product Introduction

1. The high carbon steel wire goes through anti-corrosion treatment by using phosphoric acid washing, the surface is coated with PVC to resist against corrosion from acid and alkali. The unique helix steel structure makes the hose wall smooth and able to bear external pressure.

2. Effective filtering can be guaranteed by the filtering layer, which prevents sediments flowing into the hose.

3.High strength polyester fiber: With PVC plastic-covered high strength polyester fiber as its warp, special fiber as its weft, the hose has high tensile

Performance Testing:

1.Tensile strength and water permeability             

The testing on soft water-permeable hose shows that it can bear enough tensile strength during stratum sliding, and it has good water perocolation and water permeability in all positions.

2. Acid and alkali-resistance test

    Soft water-permeable hose has good performance in acid-resistance, and provides for better protection for the organic and inorganic chemical components in water and soil.

Results of acid & alkali testing under room temperature for 72 hours are as follows:  

10%HCL solution    no anomalies 

10%NaOH solution   no anomalies

3. Pressurized flattening

With high-strength helix steel structure, the soft water-permeable hose can distribute the external pressure loads around the hose evenly.

4. Resilience performance test

    Compression at 70%, compression times up to 50, the resilience performance of soft water permeable hose should be above 90%.
