Concrete hose types: ordinary conventional type. Concrete Hose length: 4 m / root. Hose concrete structure: 2 steel wire braid reinforced layer, inner rubber wear layer, the outer protective layer of rubber, both ends of the clamp flange. Concrete Hose Application: concrete pump, car pump, to pump. End pipeline for transporting concrete, belong to the low-pressure areas, are not allowed to assemble hammers. Pressure technical parameters please users look for: 125A Normal operating pressure should not exceed 4MP, bending radius not less than 1M, each not less than 5,000 square during normal use. 150A Normal operating pressure should not exceed 3.5MP, bending radius not less than 1M, each not less than 5,000 square during normal use. 125AB high pressure using a pressure not exceed 10MP, bending radius not less than 1M, each not less than 10,000 square during normal use. 150AB high pressure using a pressure not exceeding 9.5MP, bending radius not less than 1M, each not less than 10,000 square during normal use. 125AB high pressure (enhanced) using pressure shall not exceed 12MP, bending radius not less than 1M, each of not less than 12,000 square during normal use. 150AB high pressure (enhanced) using pressure shall not exceed 11.5MP, bending radius not less than 1M, each of not less than 12,000 square during normal use.
