Introduction to inner and outer braiding of braided silicone hose时间：2021-11-15浏览次数：767
When some customers ask questions about braided silicone hoses, they have such a question: which one of the inner braided silicone hoses and the outer braided silicone hoses can withstand pressure better? Here is a simple explanation.
Braided silicone hose is also called reinforced silicone hose, and reinforced silicone hose can be divided into two types: inner braided silicone hose and outer braided silicone hose. Depending on the use, the material is also different. Ordinary low-pressure ones are usually fiber braided, while high-pressure ones are usually steel wire braided. The more layers, the greater the pressure.
At present, the so-called braided silicone hose is commonly wrapped with cloth, which can strengthen the pressure, wear resistance, corrosion resistance, etc. similarly, the more layers, the greater the pressure.
But as for the hydraulic pipe, it belongs to the internal braided silicone hose, which mainly relies on the internal reinforcing layer to resist the pressure, and wrapping cloth on the outside does not play a big role. Most of the common wrapping hydraulic pipes in the market are made in China. Because the technology is relatively backward, wrapping cloth layer by layer is still used. Other common wrapping tubes are steam silicone tubes used in the steam field for safety.
Therefore, the bursting pressure has nothing to do with the inside and outside, but depends on the manufacturer's product description. Under normal circumstances, the domestic pipeline blasting pressure is about 2 times the working pressure, of course, it can reach 3-4 times without sweeping parts. Foreign ones should be about four times. If it is applied in the high-voltage field, we must pay attention to this aspect.
