Flexible permeable hose

2023/4/28


performance

  The pipe body is supported by anti rust spring steel coils, forming a high compression soft structure. The non-woven fabric lining filters, preventing mud and sand impurities from entering the pipe, thereby achieving the effect of water purification. The outer covering layer of polypropylene fiber has two water absorption properties, which can quickly collect excess water in the soil. The rubber band integrates the wall pipe cover layer with the spring steel ring body, providing excellent water permeability. Permeable water can smoothly penetrate into the pipe, while mud and sand impurities are blocked outside the pipe, achieving the goal of water permeability, drainage, and filtration in one go.


scope of application

A. Drainage of sports fields, stadiums, airports, squares, and park green spaces.
B. Drainage of railway and highway subgrades and shoulders.
C. Vertical and horizontal drainage on the back of various retaining walls.
D. Underground irrigation and drainage systems for agriculture and horticulture.
E. Tunnel and underground passage drainage.
F. Drainage works such as coal yards and garbage landfills.
G. Mine tail dam, ash dam drainage system for hydropower plants, etc.


Acid and alkaline resistance test


  The flexible permeable pipe is made of high-strength polyester fiber and steel wire covered with PVC, which has strong acid and alkali resistance. For organic or inorganic chemistry chemical components in water and soil, the test results are as follows: (room temperature 72 hours)
10% HCL solution without appearance abnormalities
10% NaOH solution without appearance abnormalities
