Industrial hose is the bridge of any industry
1. Use a red cloth or your hands and feet to rub back and forth on the surface of the stainless steel braided mesh tube. See if the surface will change color. Discoloration indicates that the stainless steel material is poor. High-quality stainless steel will not change color.
2. The stainless steel braided strand is composed of multiple stainless steel wires. The steel wires overlap each other. Therefore, the braided layer cannot have broken wires. Use a guide or your hands to break through the surface to infer whether the braided layer has the above quality problems.
3. The higher the surface area of the stainless steel interweaving, the better the metal hose will be. Then how to distinguish the high and low braided surface areas? Just look at the gap aperture between the braided strands. The smaller the aperture, the higher the surface area. Conversely, the larger the aperture, the lower the surface area.
