The sandblasting gun inside the pipeline is a kind of arc scattering type sandblasting. The sand spreads 360 degrees with the sandblasting gun nozzle as the center and sprays out at a 45-degree angle. The pull-out speed depends on the blasting conditions.

The sandblasting gun for the inner wall of the pipeline is developed by the traditional direct-injection sandblasting gun.

Industrial steel pipes and transportation engineering pipelines need to be treated with anti-corrosion coating, and sandblasting and rust removal should be carried out before the anti-corrosion coating treatment. Sandblasting cleans the oxide layer and other impurities, so as to improve the roughness of the inner wall of the pipe, in order to achieve a firm adhesion after painting.

The sandblasting gun for the inner wall of the pipe should be used with a pressurized sandblasting machine (sandblasting tank) for sandblasting.
