Soft water pipe

Specifications. Model: HR-50, HR-80, HR-100, HR-150, HR-200, HR-250, HR-300. Diameter: (mm ± 3): 50,80,100,150,200.205.300. performance specifications. (1) phosphoric acid rust treatment high carbon steel wire, coated with PVC to prevent acid corrosion.Skeleton of steel wire helix alone does any flat wall surface and to withstand external pressure. (2) non-woven filter layer is indeed an effective filter to prevent any sediment entering the tube. (3) high-strength polyethylene fiber. High strength polyethylene fiber warp PVC plastic bag. Parallel use of special fibers, the formation of sufficient tensile strength. Scope: Road, rail, roadbed, shoulder reinforcement drainage.Sports grounds, golf courses, baseball fields, soccer fields, public. Tunnel, subway, underground passages, underground yard drainage.Drainage and other green rest. Hillside, slope development of the Soil and Water Conservation.Roof garden, flower bed drainage. At least down the back wall and a variety of horizontal drainage.Building foundation drainage construction. Jumped to the water slide.Agriculture, horticulture, underground irrigation and drainage systems. Thermal power plants, huidui drainage.Low-lying wet land drainage system. Landfill drainage management works.Site Preparation of the drainage. Performance testing. (1) tensile strength and permeability. Jiangsu Sen spring flooding source to enhance fiber-blind and other institutions authorized by the Nanjing Hydraulic Research Institute of China sample tests, the results show that the sliding layer can withstand the pull of enough, and full of water seepage, flooding Premium performance . (2) acid test. Blind pipe with high strength polyethylene fiber and steel wire covered with acid, PVC, has a strong acid and alkali resistance, water quality and soil in the study of organic and non-polar components have a protective effect. Room temperature for 72 hours pH test results are as follows:. 10% HCL solution without the appearance of abnormal. 10% NaOH solution without the appearance of abnormal. (3) Flat rate of pressure. Blind tube of high-strength spring steel wire spiral reinforced body structure, the external pressure load uniformly distributed around the tube. (4) recovery performance tests. Blind tube in the test should be 70% of the amount of compression, compression for 50 times, and the recovery of greater than 90%.
