Sandblasting hose The inner rubber layer of; The outer glue layer protects the skeleton layer from external damage and erosion; The skeleton layer is the pressure bearing layer of the sandblasting rubber pipe, which endows the pipe body with strength and rigidity. The working pressure of sand blasting hose depends on the material and structure of the skeleton layer.

According to the material and structure of the skeleton layer, sandblasting hose can be divided into full rubber hose (non-woven material), sandblasting hose (the skeleton layer is cloth layer), suction hose (there is a layer of metal spiral wire outside the cloth layer), braided hose (the skeleton layer is woven steel wire or fabric), winding hose (the skeleton layer is steel wire or rope winding layer), knitting hose (the skeleton layer is knitted fabric) Short fiber rubber hose (made of short fiber and rubber). The suction sandblasting hose works under negative pressure, and the steel wire braided hose or winding hose can withstand the pressure of 80~600MPa or higher.

    Sandblasting hose The basic production processes include rubber mix processing, cord fabric (see cord) and canvas processing, hose molding, vulcanization, etc. The processing method of the skeleton layer and the forming equipment of the rubber hose with different structures and different skeletons are different. Since the full rubber hose does not contain a skeleton layer, it is only necessary to use a press out machine to press out the hose;
