Sand Blaster Hose Has Strict Standards

Many people may not familiar with the wear resistant sand blaster hose. But it is not that mysterious. Because from the name, we can know that it has good wear resistance. But there are still some aspects that are uncommon for people. Then, let me introduce you the sand blasting hose next.

The inner rubber of blast hose is PU or butyl rubber. Besides, there are special reinforce agents. The color of the inner rubber is yellow and clear. While it highly resist wear and high pressure. After the test, the abrasion resistance of such hose is 2-3 times than that of normal blaster hose. Because of this, this kind of blasting hose pipe is very popular in various industries.

Each rubber hose has a certain standard. If abrasion resistant hose fails to meet the standard, then it must be of inferior quality. Only the standard hose can be sold on the market. Because a bad blasting hose will not able to finish the blasting work. Besides, it may cause operator get hurt.

Technical standards for sand blaster hose

The work temp of the sand blasting hose is -20-70℃. Besides, the shot blast hose should have 3 layers. They are inner rubber tube, reinforce layer and rubber cover.

In terms of pressure, the max working pressure of the sandblasting hose is 0.63MPa. In the test under twice the working pressure, there should not be water seepage. Besides, there should not be local bulging and expansion. The burst pressure of the abrasive blasting hose should not be lower than 4 times of the working pressure. Keep the pressure for one minute and the length difference can not beyond 0.8%. While the difference of outer diameter can not beyond 10%. Besides, the sand blasting pipe should be anti static.

This time we learned the pressure standard for a sand blasting hose pipe. Next time let’s learn other standards. Follow Orientflex hose and learn more.
