Sand pipe
A sandblasting rubber hose suitable for air-pressure sandblasting and rust removal on metal surfaces, blasting, and wet sandblasting and dry sandblasting in engineering construction. The sandblasting pipe should be composed of the following parts:
-Inner lining (inner rubber layer)
-Reinforcement layer of natural or synthetic fabric laid with appropriate methods
-Outer covering (Outer rubber layer)
Among them, the reinforcement layer mostly adopts the rubber cloth sandwiching method and the cord winding method.
The maximum working pressure of the hose is .3.
When the hose is subjected to hydraulic testing at twice the working pressure, it should have no water seepage, no local bulging, no expansion, and no other abnormal phenomena. The antistatic hose maintains pressure and its length should not change by more than 100 meters, its outer diameter should not change by more than 100 meters, and its twist should not exceed 100 meters.
The bursting pressure of the hose should be no less than three times the working pressure.
<3>As the main performance of sandblasting hose, it is also the main basis for users to judge the quality of hose. Current industry standards/- stipulate that according to the method, the wear volume does not exceed 3. (The test method used in the old version of the industry standard was: Akron abrasion method - the wear volume does not exceed .3/.. Although this method has been replaced by the method after this year,
