It is suitable for conveying hydraulic fluids such as alcohol, fuel, lubricating oil, emulsion, etc. It is distinguished from hard pipes in appearance. The biggest feature of rubber hoses is flexibility. The design of hoses varies greatly according to the operating conditions and performance requirements. Common parameters include size, pressure, weight, length, curvature, chemical durability, etc. Compared with civilian hoses, the industrial operating environment is more complex and harsher, and the equipment has more stringent requirements on the conveying pipes.
