How to keep the condiment deliver hose clean
There are so many brands of sandblasting hoses on the market. How to choose sandblasting hoses?
First of all, customers need to know the type of sandblast hose they need. Currently, there are three common types: light, heavy and vacuum hoses.
These three different types are suitable for different fields of use and have different requirements for the construction environment. Therefore, this must be made clear before purchasing. Secondly, choose products with good quality.
In addition, after choosing a brand with a good reputation and quality, it is also necessary to note that almost every brand has high-end, mid-end and low-end products.
The inner and outer layers of the high pressure hose wall are oil resistant rubber, and the middle is (2 to 4 layers) cross-woven steel wire or winding steel wire.
Poor quality hoses will have the following situations
The thickness of the hose wall is uneven
Steel wire braiding is too tight or too loose or the number of steel wire layers is too small
The deformation of the hose after pressurization is large
The outer layer of rubber has poor air tightness, resulting in steel wire rust
Inner layer of rubber has poor sealing, which allows high-pressure oil to easily enter the steel wire layer.
The adhesiveness between the rubber layer and the steel wire layer is insufficient.
