Extend hydraulic hoses lifespan

This article works out how to extend hydraulic hoses lifespan, some factors including storage, environment, and usage are covered in the whole life of the hydraulic hose.

Hydraulic hoses are crucial to the smooth operation of a wide range of machinery. These hoses deliver pressurized fluid to the machinery for motion control.

When selecting a hydraulic hose, you might feel going for the best one on the market is enough. Although it is important to use good materials, proper management ensures that your setup runs for a long time.

In fact, proper management is key as it protects the entire system from breakdown. These five tips will help you prolong the life of hydraulic hoses and guarantee you a seamless operation.

1. Store Correctly

Hydraulic hoses last longer if stored properly. By storing them correctly, they become able to withstand environmental difficulties and avoid failure.

Temperature is the first factor to consider when deciding where to store your hydraulic hoses. High temperatures may cause a breakdown in the materials, while low temperatures make hoses rigid. The ideal temperature range for storing a hose is between 50 and 70 degrees Fahrenheit. 

Furthermore, you should store your hydraulic hoses away from chemicals or factory machinery. Keep your storage location clean and clear of pests that might gnaw on the hoses. 

To make this easier, you can simply store your hydraulic hoses in their original packaging. Aside from extending the hoses’ lifespan, proper storage ensures that the hoses are ready for use at a later date.

2. Use the right hose for your system

There are different types of hydraulic hoses, so it is important to get the right one for your hydraulic system. The right hose for your system will depend on different factors, including the hydraulic machine design, pressure rating, temperature range, cover material, and bend radius.

Your hydraulic hose will not last if you exceed its temperature range, bend radius, or pressure rating. On the other hand, you can extend the lifespan of your hydraulic hose by using it according to these specifications.

In particular, you should try not always to reach the maximum, as it could wear the hose over time. Finally, do not pass the wrong fluids through the hose.

3. Protect your Hoses with Hose Guards

To extend the lifespan of your hydraulic hoses, you can opt for spring guards or coil hose guards. They are useful wherever you need protection against abrasion, cuts, accidental compression, and deep gouges.

Spring guards are typically made of steel and are zinc-plated to prevent rusting. They are available in various sizes that exceed the hose’s outer diameter. As a result, you can easily get one to fit your hose.

Also, they come in standard lengths or large coils that you can trim to size, and installation is as easy as slipping them over the pipe. Coil hose guards are designed to slip over the outside diameter of the hose, much like a spring guard.

4. Install abrasion sleeves

Abrasion is one of the major factors that damage hydraulic hoses. You significantly reduce the risk of abrasion damage when you put in abrasion sleeves.

These sleeves are made of different materials, including textiles and polymers. However, most hydraulic hose abrasion sleeves in the market are made of nylon.

Nylon is resistant to wear and tear, which makes it dependable as a secondary line of defense against environmental hazards. The sleeves are usually thick but not heavy, guaranteeing the hose’s flexibility and security.

5. Carry out regular inspections

When you detect hydraulic hose damage on time, you can also fix it on time, which increase its lifespan in the long run.

About once every three months, you should inspect hydraulic hoses on your stationary machinery. On the other hand, you should inspect the hoses on any mobile machinery at least once every three months.

However, in some cases, more regular inspection is necessary. For instance, hoses connected to heavier machinery or subjected to high temperatures and pressures during operation need more frequent inspections.

Factors that reduce the lifespan of hydraulic hoses 

  1. Heat.
  2. Trapped Air.
  3. Wrong Assembly.
  4. Passing the wrong fluid through the hoses. 
  5. Abrasion.
  6. High Pressure. 
  7. Chemical Erosion. 
  8. Tears and rips. 

Types of Hydraulic Hose Damage

Your hydraulic hose can suffer different types of damage. Knowing these different types will help you better manage and prevent them from occurring. Check out some of the most common types below:

Damage from bend radius

When a hydraulic hose is bent too much or too little, the tube and its cover might rip through. If the hose is routed incorrectly around tight corners, it could separate at the ends, leak at the crimps, or rupture.

All of these can render the hose useless and even dangerous. In addition, there may be a minimum bend radius inaccuracy even though the hose seems flat in certain areas, which will severely restrict the flow.

Ensure you follow the minimum bend radius and adjust your route accordingly to prevent this problem.

Damage from aged or dry air

A hydraulic hose’s inner tube may develop several fractures, albeit tiny, if the air within has been stagnant for a long time or is very dry.

Due to the hose’s continued pliability, this kind of breakdown might be hard to detect. In most cases, the hose underneath the fittings shows no evidence of breaking. However, you will notice external leakage.

You should check the hydraulic hose’s extreme dry-air rating to prevent issues related to dry or aged air. In addition, if the hydraulic system allows it, you can try raising the dew point.

Damage from tube erosion

Often, external leakage is the result of hydraulic hose tube erosion. Narrow, high-velocity fluid streams or tiny particles suspended in the fluid typically cause this type of erosion.

You can prevent hydraulic hose tube erosion by using the correct hose size according to the recommended velocities. In addition, ensure the fluid medium is not excessively abrasive for the inner tube and that the hose assembly is not bent too tightly.

From the technical requirements of your hydraulic hose, you will find the maximum bend radius and diameter you must comply with during assembly.
