Steel wire braided hose/DN80 fine stone mortar pump conveying rubber hose/6 meters wear-resistant hose

[Use of concrete pump hose] It is suitable for rubber hoses such as high-rise buildings, highways, tunnels, water conservancy projects, nuclear power plants and other construction machinery, and concrete pump truck transportation. [Application Scope] It is used at the tail of the pump to transport concrete to the pouring position. It can resist suction during cleaning. It is usually equipped with a buckle-type hardened joint. [Temperature range] -℃ to +℃ [Product structure] Inner rubber layer, reinforcement layer, outer rubber layer, inner rubber: Polyurethane and butyl rubber are used as the main raw materials, and special reinforcing agents are added to make the compound rubber. The color of the finished inner rubber is black and transparent. It has the characteristics of high wear resistance, high toughness, high pressure resistance, smoothness, etc. It can withstand the friction of concrete. The inner rubber layer has the function of allowing the conveying medium to withstand pressure and protecting the steel wire from erosion. . Reinforcement layer: A layer of steel wire wrapped with special steel wire braiding for copper-plated hoses. It can withstand working pressure 3-times that of ordinary hoses. It has the characteristics of high pressure resistance and superior flexural resistance, and serves as a reinforcement. , Outer rubber: black, smooth (surface covered with cloth), BR/mixed rubber, anti-aging and wear-resistant. [Material] Natural rubber + steel wire braid [Technical parameters of operating pressure] The operating pressure of the ordinary type shall not exceed, the bending radius shall not be less, and each rod shall not be less than the conveying capacity of cubic concrete during normal use. 2. The operating pressure of the ordinary type shall not exceed 3., the bending radius shall not be less than, and each rod shall not be lower than the transport capacity of cubic concrete during normal use. 3. The operating pressure of B high-pressure steel curtains shall not exceed, the bending radius shall not be less than, and each piece shall not be less than the conveying capacity of cubic concrete during normal use. 4.
