Silicone hose sleeve offers you excellent hose protection solution
Sand blast hose is the necessary part for a blaster. While it is to spray high abrasive materials like sand and shot. Blaster hose sprays such mediums to the surface of metal equipment, steel pipe, etc for the cleaning work. Because sand blasting can effectively remove the rust and impurity on the surface. Because of the harsh work condition, it requires the shot blast hose has great property.
Sand blast hose performance requirements
First, in the hydraulic test at twice the working pressure, there should not be water seepage. Besides, it should be free of local bulging, expansion and other problems. The anti static hose maintains pressure for 1 minute. Then its length should not change more than±0.8%. At the same time, its outer diameter should not change more than ±10%. In addition, its twist per meter should not exceed 60º.
Second, bending property
At 23℃, test the blaster pipe with a min bending radius of 10 times the inner diameter. While the deformation KD value should not exceed 0.8 times the outer diameter. (K is the ratio of the outer diameter of the hose before bending minus that after bending to the outer diameter before bending.) In addition, when you test the pipe blast at-25±2℃, there should be no cracks after bending.
Wear resistance property
Wear resistance performance is the most important property of sand blast hose. At the same time, it is the main factor to judge if a sandblasting hose is good in quality. On the market, there are lots of suppliers. However, the shot blasting hose quality is quit different. Therefore, the wear resistance test is necessary.
