According to the pressure requirement of sandblasting rubber hose, the double-layer cord can resist the pressure of 40KG, which is completely sufficient, and increases the thickness of wear-resistant rubber layer and the flexibility of rubber hose. The exported rubber hose and the rubber hose produced abroad have long been out of cloth, so it can be said that the rubber hose with cloth is outdated.
The patent name of cord winding hose in China is Bengbu Shelley hose. We have purchased things from his home, and the formula is rigorous, so the quality is very good.
PS: I saw the reply downstairs. LZ asked if there were any shortcomings in the cord and the cloth. I think this recovery line is better than the cloth used in normal occasions, so there is nothing wrong with it. The pressure of rope and cloth is really determined by the number of layers. I can reliably say that the double-layer cord of 5 1mm rubber hose can bear 40KG. As for the cloth sandwich, hehe ... calculate for yourself, two layers can't resist 40KG.
As for the steel braided pipe, it is a high-pressure pipe, which has nothing to do with LZ.
