Sandblasting pipe Generally, light sand blasting pipe and heavy sand blasting pipe can be divided according to the working conditions and the loss of material particles to the transport medium. The spiral steel wire will make it suitable for negative pressure environment. It is generally used in the application environment such as ship sand blasting and quicksand operation; The common inner rubber is wear-resistant NBR (natural rubber) material, and the outer rubber is wrapped with compound rubber.

Heavy sandblasting pipe is used for equipment sandblasting sand gravel, fine pebble, slurry and other application environments. The sandblasting vacuum tube is embedded with spiral steel wire, and the vacuum negative pressure can reach 0.9 bar in general. Sandblasting hose Technical specifications; Only standardized products can make users feel at ease. Next, let's talk about its technical specifications. In terms of application temperature, the temperature of sandblasting hose is generally - 20 - 70 ℃.

In terms of data and structure, the sandblasting hose should have the following composition. An inner rubber layer is required. There is a reinforcing layer, which is composed of natural or synthetic materials paved by appropriate methods, and it is mostly made by the method of laminated cloth and cord surrounding. 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, Sandblasting hose The bursting pressure of shall not be less than 4 times of the working pressure.
