Inner glue of spraying pipe of shotcrete machine: Polyurethane and butyl rubber are used as main raw materials, and special reinforcing agent is added. The finished rubber has the characteristics of high wear resistance, high toughness, high pressure resistance, etc. The wear resistance index is 2-3 times that of ordinary sand blast hose. The reinforced layer steel wire grouting pipe adopts high-quality wear-resistant rubber as the reinforced layer, which has good flexibility and strong pressure bearing capacity;The steel braided spray pipe of shotcrete machine is braided with special steel wire of copper-plated rubber hose. The working pressure is 3-4 times that of the cloth hose. It has the characteristics of high pressure resistance and excellent flex resistance. Therefore, the spray pipe of shotcrete machine is widely used in various tunnel projects, wells, caverns, slope protection and spray anchors. It has a wide range of applications in hydropower, mining, military defense and other fields.
Product features of spraying pipe of shotcrete machine: The spraying pipe is made of special synthetic rubber, which has excellent aging resistance; the steel braided spraying pipe has high pressure bearing and excellent pulse performance; the pipe body is tightly combined, and the use of soft, pressure The lower deformation is small; the spray pipe has excellent bending resistance and fatigue resistance; the length of the steel wire braided spray pipe is large, which can be customized according to customer needs. Technical inner diameter specification of steel wire braided hose (diameter φ25, --- φ64).
Finally, remind you that the spraying pipe of shotcrete machine should be checked before use: the bending radius of the spraying pipe should not be less than the given bending radius to prevent damage to the hose skeleton or early damage due to excessive stretching; according to the conditions of use, choose the sandblasting pipe correctly Varieties, specifications, do not misuse or substitute. When the working place changes, the spraying pipe of shotcrete machine should be moved off the ground, and it should not be dragged to avoid corroding the skeleton layer after scratching the external glue.
