Wear resistant rubber hose It belongs to a general term of a large category, which can be subdivided into special pipes for shield machines, and wear-resistant pipes used in industrial and mining enterprises, subway construction and other projects. Because the working mode is different from the medium conveyed, attention should also be paid to its wear-resistance when selecting conveying pipes. Whether the medium can be transported. Today, we mainly introduce the cord sand suction hose and cord for conveying cement and sand Sandblasting hose 。

The inner layer of cord sand suction hose is made of black NR&SBR wear-resistant synthetic rubber, the reinforcing layer is made of multi-layer synthetic fabric, and the outer rubber layer is made of black synthetic rubber. It is generally used to transport cement, sand and other fine particles. It has good wear resistance. The outer glue has good aging resistance and wear resistance. The bursting pressure is not less than three times of the working pressure.

Cord sand blasting hose The inner layer is made of black wear-resistant synthetic rubber, the reinforcement layer is made of multi-layer synthetic fabric layer+spiral steel wire layer, and the outer rubber layer is made of black oil resistant synthetic rubber, which is generally suitable for pumping solid or granular materials such as mineral sand, river sand, coal chips and cereals (rice, wheat, corn). The rubber hose has good bending performance, the inner rubber has good elasticity and wear resistance, and the outer rubber has good aging resistance and wear resistance. It has the dual performance of bearing positive pressure and negative pressure, and can be used normally under the vacuum condition of - 80kpa (600mm Hg). The burst pressure of the rubber hose is not less than three times of the working pressure.
