Sandblasting hose Technical standards of
Only standard products can reassure users. Next, let's talk about its technical standards.
In terms of operating temperature, the temperature of sandblasting hose is generally - 20-70 ℃.
In terms of material and structure, sandblasting hose should have the following composition. One needs an inner rubber layer.
2、 There is an enhancement layer, which is composed of The method is composed of natural or synthetic materials, which are mostly made by the glue cloth method and the cord winding method. Third, it has an outer glue layer. In terms of hydraulics, the standards are as follows. The working pressure of sand blasting hose is 0.63MPa. When it carries out the hydraulic test work under twice the working pressure, no water seepage, local bulge, expansion and other abnormal phenomena are allowed.
The pressure of its anti-static hose should be maintained for one minute, but the length change should not exceed 0.8% of the upper and lower, the outer diameter change should not exceed 10% of the upper and lower, and for each meter, the torsion should not exceed 60&ORDM. Finally, the bursting pressure of sand blasting hose shall not be less than 4 times of the working pressure.
