About Abrasion resistant sand blasting hose Many users will be unfamiliar with the relevant knowledge of, in fact, it is not difficult to understand, but from its literal meaning, it can be known that it has good wear resistance. In addition, under the explanation of relevant personnel, we can understand that for wear resistance Sandblasting hose Its inner rubber is made of polyurethane and butyl rubber as the main raw materials, and special reinforcing agent is added. The inner glue of the finished product is yellow and transparent. It has the characteristics of high wear resistance, high toughness and high pressure resistance. The wear resistance index is 2-3 times of that of ordinary sandblasting hose. It is precisely because of its wear resistance that it enjoys the reputation of "wear king" in the same industry.

Each product will have its corresponding standard. If it fails to meet the standard, then the product must be of inferior quality. If it meets the standard, it can be regarded as qualified and can be sold in the market. about Sandblasting pipe As far as we are concerned, there are also specified standards. Only when we reach this standard can we use it with more confidence.

1. Technical standards of sand blasting pipe:

The use temperature of sandblasting pipe is - 20&-- 70 ℃. The sandblasting pipe must have three layers in structure, namely, the inner rubber layer, the reinforcement layer and the outer layer.

In terms of hydraulic pressure, the maximum working pressure of sand blasting hose is 0.63MPa. When the hydraulic experiment is carried out under twice the working pressure, no water seepage, local bulge, expansion and other abnormal phenomena are allowed.

The bursting pressure of sand blasting hose shall not be less than 4 times of the working pressure. The pressure of anti-static hose shall be maintained for one minute, but the length change shall not exceed 0.8% of the upper and lower, the outer diameter change shall not exceed 10% of the upper and lower, and the torsion shall not exceed 60&ORDM per meter.

2. Bending standard of sand blasting hose:

When the temperature is 23 ℃, the deformation value shall not exceed 0.8 times of the outer diameter when the smallest bending radius within 10 times of the nominal inner diameter is tested, and the cracking phenomenon shall not occur when bending at minus 25 ℃.

3. Wear resistance standard:

According to the test standard of ISO4649 for wear resistance of materials, the wear volume of sand hose shall not exceed 40MM&SUP3. The above is the standard for judging whether the quality of sandblasting pipe is qualified. If it fails to meet the standard, it is basically unqualified products.

In addition, we also learned that for Abrasion resistant sand blasting hose The reinforcing layer of is braided with special steel wire for copper plated hose, which can withstand the working pressure of 3-4 times that of cloth clip hose. It has the characteristics of high pressure resistance and excellent bending resistance. Here is a brief introduction to the relevant knowledge of this product. I hope that through the explanation of this knowledge, we can help the users in their applications.
