Basic Hose Construction
Hydraulic rubber hoses are known for their great flexibility, affordability and durability. Generally speaking, a hydraulic hose consists of at least three parts – an inner tube which carries the fluid, a reinforcement supporting the tube and an abrasion and ozone resistant cover.
1. Inner Tube
Inner tube is flexible and durable. Common materials for making this tube are synthetic rubber, thermoplastics and PTFE. It works well with most petroleum- and water-based hydraulic fluids. If the tube reacts with the fluids, the hose will be prone to leakage or be at risk of an accident. When you are not sure about the relationship between the tube and the liquid to be carried, consult us and we will get back to you soon.
Hose reinforcement is taken as a sheath protecting fragile tube. It is used to be multiple layers of braided textile, wire or spiral-wound wire. It can support different grades of pressures according to your applications.Textile reinforcement, whether single or double layers, is ideal for tight routing and low pressure system such as return and suction systems. Braid wire and spiral wire are usually for high working pressure. If the system has severe requirement of impulse fatigue, spiral wire reinforcement is the priority.
3. Outside Cover
Cover is the first barrier to guard the hose. It is usually made of abrasion and weather proof synthetic rubber to resist oils, chemicals, ozone and other adverse factors from outside environment.
