The Most Common Reasons for Hydraulic Hose Failure

13 Sep.,2023

 

There is one thing all hydraulic hoses have in common. Sooner or later, they are going to have to be replaced. While there’s no way to know how long the hose will last, there are some common reasons why they fail and sighs you can watch for.

So what are the most common reasons for hydraulic hose failure?

The most common reason hoses fail is precautions weren’t taken, and no one noticed the common signs of failure.

Below we have outlined some of the most common reasons hydraulic hoses fail and the main signs to look for. Just a few extra minutes can make all of the difference in how long your hoses will last. So, if you’re interested in learning more, keep reading.

Tube Erosion

Tube erosion is a common reason for hydraulic hose failure. It is commonly caused by concentrated high-velocity steam of fluids that may or may not contain particles. This steam will gradually erode the inner tube of the hose. If not caught in time will cause leaks on the outside of the hose.

The main reason this happens is due to incorrect size hoses and improper amounts of fluid for your hydraulic machine. Another cause is the hose assembly is not bent correctly. If it is not turned correctly, then it does not allow the fluid to flow freely.

Dry Air

Dry or aged air is another reason hydraulic hoses can fail. Dry air can lead to small cracks in the house, which are difficult to spot because they will still bend easily. There will be signs of external leaks if this happens.

The best way to avoid this is to make sure you invest in hoses made for dry air. The best way to ensure you have the correct hoses is to consult your local hydraulic system specialist. One last tip is to increase the dew point on the machine if possible.

High Temperature

Hydraulic hoses often are exposed to high amounts of heat, but when they are exposed to heat that is too hot, it can lead to damage. Whether the heat comes from the tube itself or the hydraulic fluid, it leads to the same type of damage. Overheating causes the hose to crack and become stiff. One of the main signs is that it may turn black. Once removed, the hose will see and hear the cracking when you flex it.

To prevent heat hardening, you must make sure you use a hose with the proper heat rating or lower your temperatures. If you can’t lower the temperature, you can purchase heat guards and shields to reduce the heat the hose is exposed to.

Incorrect Fluid

Some people don’t realize that not all hydraulic fluid is compatible with all types of hoses. This is because hydraulic fluid’s chemical makeup may react adversely to elastomers that make up the hydraulic hose. Incompatible fluids will cause the inner tube of the hose assembly to deteriorate and swell. Many times you may not realize this is happening, and the hose may fail without any warning.

The best way to avoid this is to simply make sure that when you purchase hydraulic fluid, you make sure that it is the correct type.

Abrasion

Abrasion is one of the most common reasons hydraulic hoses are damaged. This is especially true for shops where their machines go through upwards of a hundred cycles in a day. Not only does it matter how frequently the machine is used but also if you’re using the incorrect fluid when hoses rub against if they have contact with moving parts or sharp edges.

A few ways to avoid this is to make sure your hoses are correctly routed when it’s installed. You can also purchase hose guards for the areas hoses are touching moving parts. The main sign of damage is to the cover of the hose.

Poor Routing

Hydraulic hoses will fail quickly if the hose does not seal well where the hose and crimp seal meet. Another issue with hose bends is if the bend radius is exceeded. If the turn is too large, it is likely your hose will kink and crush, restricting the flow.

The best way to avoid this is to adhere to the minimum and maximum bend requirements. The correct clamps and fittings should be used properly. The best way to prevent this issue is to have your hoses installed by a qualified hydraulic repair technician.
