Description for concrete pump rubber hose: 1. Tube: black conductive NR-abrasion resistant 2. Reinforcement: high tensile textile cords 3. Cover: black conductive SBR/NR-abrasion and ozone resistant 4. Temperature: -30 °C +80 °C
Structure for Concrete Pump Rubber Hose: inner layer rubber, enhancement layer, outside layer rubber. 1. Inner layer rubber: polyurethane and butyl rubber are the mainly material, and put in special reinforced material to make mixed rubber. It is high wear resistance, high toughness, high pressure, smooth and so on. 2. Enhancement layer: 4 layer of steel wire , the use of copper wire braided hose, bearing the work pressure is the ordinary hose 3-4 Times, with a high degree of resistance, flex features superior performance, enhancing effect. 3. Outside layer rubber: Black, smooth (wrapped), SBR/NR compound, anti aging, wear resistance.
1. Lifetime: Our concrete pump rubber hoses be able to use 25,000 cubic meter compared with normal quality of 12,000-15,000 cubic meters in China. 2. Integrated hose end and inner wall hardened, prolong working life. 3. Reinforcement: 4 layers steel wire, 2 layers steel wire, 4/6 layers fabric 4. Hose ends: galvanized or painted
