What to Know About Hydraulic Hoses

Everything You Need to Know About Hydraulic Hoses

History shows that hydraulic systems have been in use since the early 1940s when a group of engineers came out with a more compact, lighter and even self-lubricating. The use of hydraulic machinery by the military was stirred by World War II. When flexible hydraulic pipes were discovered, it led to the development of other machines that were powered by hydraulic energy.

What is a hydraulic hose anyway? Well. A hydraulic hose is a synthetic rubber, high pressure or thermoplastic pipe that usually carries any fluid (petroleum, synthetic oil, and water) to transmit some force within a hydraulic system/machinery. How is this hose constructed?

This hydraulic hose is made up of 3 main parts namely inner tube, a sheath and spiral wound wire. The inner tube usually carries the transported fluid while the outer protective layer usually protects the hose from adverse weather, oil or chemicals. These pipes are made for various specific mechanical applications. They have specific connectors, sizes, and lengths that enable them to fit into certain specific machines.

The Lifespan, Types and the Purpose of Hydraulic Hose

You are already aware that nothing in this world is permanent even you. That’s on a light note. However, hydraulic hoses are also not meant to stay forever and it is affected by various conditions. For example;

  • Twisting the hose
  • Kinking
  • Flexing it much
  • Crushing
  • Scratching its surface
  • Stretching the pipe

Also, a major determinant of the life span is the level of temperature. Either too high or too low-temperature increases or decreases the internal pressure of the hose. In addition, avoid using wrong types, sizes or weight of hoses to avoid any breakages. Some of them show some swelling, blisters, bubbles, cracking or even no signs when they are worn out.

The lifespan of a hydraulic hose is also determined by the type of the pipe. Some of the types include:

  • Reinforced rubber hose – its light but cannot withstand high temperatures
  • Steel reinforced Teflon hose– is a strong, light and can withstand high temperatures. They are either return lines or coiled hoses.
  • Corrugated and articulated hose – they are flexible and can accommodate pressure

It is recommended you replace the hose before any sign of failure mostly in heavy hydraulic machinery and brakes of vehicles. Unlike mechanical systems that require gears, chains, and pulleys to move a fluid from the engine, the hydraulic system transmits force through the hose from the force engine.

Fluids in these hoses transmit the force very effectively because of their incompressibility. The force from one end goes to the other end using very little power. When changing the pipe ensure you use the right sizes because they either rise or drop the force in the pipe.

Every hydraulic hose has certain specific ratings depending on the working temperature ranges and the level of pressure. Check the number on the hose before fitting them.

Safety and Maintenance of a Hydraulic Hose

When it comes to the safety of this hydraulic hose, you need correct selection, maintenance, and even replacement. This will decrease the risks when using hydraulic machinery systems. Always have a maintenance routine like on monthly basis and also don’t ignore any leakages especially where there are inflammable sources.

Always replace damaged or any old hose since they are potential hazards, avoid any contamination by cleaning the pipe thoroughly before replacing it. In addition, maintain correct temperature and pressure.

In conclusion, maintain you hose properly despite being the smallest part of a hydraulic system and machinery since it can cause the largest problem and even serious injuries.
