Hydraulic hoses are used in a variety of industries to transfer fluid and pressurize fluid systems. Knowing the right hydraulic hose for your application can help ensure you get the job done safely and efficiently.
Hydraulic hoses are designed to withstand high temperatures and pressures. However, a poor selection or installation can reduce their lifespan and lead to leakage.
Series of industrial hydraulic rubber hoses
The industrial hydraulic rubber hose series is designed for use with petroleum and water-based fluids. It can handle temperatures from -40 deg C to 100 deg C and is available in single, two or three braided steel wires.
These hoses are used in hydraulic-powered lift equipment and lubrication lines with a smaller outside diameter. They are also resistant to abrasion and can withstand harsh environments.
Hydraulic rubberhoses are made from three layers: an inner synthetic rubber rubber core, a 2-wire steel braid and a rubber cover. The rubber covers are abrasion-resistant, lightweight, and easily manipulated.
Another type of hose is the thermoplastic hydraulic hose, which uses two layers of polymer material separated by a middle reinforcement layer. The outer layer is typically made from a synthetic rubber compound that is resistant to ozone, abrasion, and other chemicals.
Insulation sleeves can extend the life expectancy of a thermoplastic pipe by protecting it against extreme temperatures. Excessive exposure to hot equipment parts or other high-temperature sources can reduce a hose’s service life by up to 80%.
Depending on the material used acceptable internal temperatures can range from -65 F (Hytrel or winterized rubber compounds), to 400 F (PTFE). External temperatures can be a problem when a hose is exposed to a turbo manifold or other hot equipment parts.
precautions for installation of hydraulic rubber hose
Hydraulic rubberhose is a common component of hydraulic and fluid-power equipment. It moves liquid between pumps, valves, tanks and other components to ensure a consistent flow. It can withstand hundreds of thousands of pressure cycles without failure if properly selected, installed and maintained.
Hydraulic hoses typically have an inner tube of rubber or thermoplastic, which carries the liquid, and a cover that protects it from weather, oil, and ozone. A reinforcement layer of sheath braided or spiral wound wire or textile yarn is also included to strengthen and support the tubing.
But improper hose installation can lead to a variety of problems. These include reduced hose life, pinhole leaks, ruptured hoses, damage to external components, and loss of hydraulic flow.
Avoid twisting a hose or exceeding the minimum radius of bend when installing it. Twisting can cause the reinforcing layer of hose to deviate from its theoretical neutral angle, which reduces the carrying capacity of the hose.
When possible, route hydraulic lines parallel to machine contours. This prevents excessive flexing during pressure cycles, and can protect lines from internal damage.
You should also inspect your hoses for potential leaks and deterioration. This will save you money over the long-term by avoiding the need to replace hoses and reducing maintenance costs.
media transmitted by hydraulic rubber hoses
Hydraulic hoses transport hydraulic fluids from or to pumps, motors, valves, and other system components. They are an integral part of the system and must be flexible and durable to work in high pressure and temperature environments.
Hydraulic hoses typically consist of an inner tube, one to three layers of reinforcement and an outer cover. Each component must be selected with the intended application in mind to provide a safe, reliable and long-lasting solution.
In addition, the hose’s tube compound, cover and fittings must be chemically compatible with the fluid being transported. This will vary depending on the fluid type, concentration, temperature, and contamination.
For example, petroleum-based hydraulic oil can be transported by most rubber hoses, but synthetic oils need special materials. Other common media include water, emulsions of mineral and hydraulic oil, fuel (excluding gasoline), and greases and gases.
Depending on the working pressure, hydraulic hoses can be divided into low-pressure and high-pressure types. The high-pressure types are reinforced by braided textile, wire or spiral wire to support a higher pressure.
