What are the different types of hydraulic hose?

Hydraulic hoses have different uses

A hydraulic hose is designed to allow hydraulic fluid to pass through. It is flexible, often reinforced, and usually made from several layers of reinforcement, as hydraulic systems often operate at very high pressures.

Different hoses have different uses and it’s important to use the correct one for the right application. Very often systems remain dormant because the incorrect hydraulic hoses are installed and this leads to a breakdown.

Reinforced rubber hoses are lighter than metal hoses. They can be strengthened by adding fibreglass or mesh, which will avoid any bulging or bends in the hoses. Rubber is also very heat resistant and is easily adapted to connect with the various hose fittings on the market.

If a rubber hose’s resistance to heat isn’t enough for the system, then Teflon can be the answer as it is even more resistant to heat. A Teflon hose can be used beside boilers or blast furnaces, thanks to its strength and ability to resist heat. If a requirement is that the system must weigh less, for example at sea, then Teflon is a good, lightweight choice.

Mechanics favour coiled hoses

The return lines allow fluids to return to a pump where the pressure is released. Cheaper hoses can generally perform well, but if these hoses are not correctly maintained or replaced, this can result in a breakdown. Coiled hoses are the answer for welding and repair facilities. They are favourites with engineers and mechanics because they snap easily back to where they belong.

According to Machine Design, hydraulic hoses must withstand extreme temperatures to minimise downtime and maintain productivity. They are commonly used under car bonnets, as well as in aircraft and forestry equipment, heavy construction vehicles, and drills and rigs used in the oil and gas industries.

Corrugated hoses can accommodate pressure surges and articulated hoses offer design flexibility as they are easily manoeuvered around corners.

There are a number of elements to take into account, including size, inside and outside diameter, length, temperature, and use of the hose. It’s important to take into consideration the material to be carried and whether or not the tube of the hose is compatible. Pressure is another factor.
