Structure of sand blast hose
The sand blast hose has same structure with slurry hose and dredge hose, which is composed of three layers: inner layer, reinforcement layer and cover layer.
Inner layer. High quality rubber for high wear and abrasion resistance.
Main materials of inner layer is polyurethane and butyl rubber. The raw materials are added into special reinforcing agents, which make the inner layer high abrasive resistant, high toughness and high pressure resistant. The abrasive performance is equal to 2 or 3 times of traditional sandblasting pipes.
Reinforcement layer. Suitable for both low or high working pressure conditions.
Fabric reinforcement + steel spiral wire reinforcement. It is suitable for the low working pressure applications.
Cord thread reinforcement + steel spiral wire reinforcement. It is suitable for the high working pressure applications.
Cover layer. High quality rubber for anti-aging and wear resistance.
Cover layer material is same to the inner layer, which is made from various abrasion and wear resistant synthetic rubber (NR, SBR, BR) for anti-aging and anti-wear performance.
