How often should you regularly test and inspect your hydraulic hose system? We answer that question and more in our hydraulic hose maintenance guide.

Hydraulic hose systems play a crucial role in industrial machinery and equipment operations. A well-maintained hydraulic hose system can ensure efficient, smooth, and safe operations. However, these hoses need constant care, inspection, and testing to guarantee their performance and safety. We’ll explain the basics of hydraulic hose system testing and how often you should conduct tests.

Hydraulic Hose Inspection and Testing Frequency

Establish an inspection and testing routine to ensure the best performance of your hydraulic hose system. Generally, a hydraulic hose system requires inspection based on the following guidelines:

Visual Inspection

Check for visible damage, such as leaks, cracks, or kinks, at least once a month or more frequently if your system is exposed to harsh conditions or operates under high pressure.

Functional Inspection

Perform a functional inspection every time you and your team operate the system. Listen for unusual noises or vibrations, and monitor your system’s performance to ensure its efficiency.

Regular Testing

Industry experts recommend thoroughly testing your hydraulic hoses at least once a year. The frequency may vary depending on your system’s usage and environmental factors.

How to Test Hydraulic Hoses

You can perform various tests on your hydraulic hose system to ensure its reliability and safety. Below are two essential methods: hydraulic hose burst testing and hydraulic hose salt-spray testing.

Hydraulic Hose Burst Testing

Hydraulic hose burst testing, also known as on-site hydrostatic pressure testing, measures the capability and durability of the hose system. This test determines if a hose can withstand the pressure it’s designed for and identifies any weaknesses.

Here’s how to perform hydraulic hose burst testing:

1. Secure the hose assembly to a test rig or other support structure.

2. Connect the hose to a hydraulic pump.

3. Increase the pump’s pressure gradually until it reaches the hose’s maximum pressure rating.

4. Observe how the hose responded to the applied pressure, and note any issues or weak points.

Hydraulic Hose Salt-Spray Testing

Hydraulic hose salt-spray (also known as salt fog) testing assesses the resistance of a hose’s outer protective layer to corrosion from various environmental factors, such as water, salt, or chemicals. This test is crucial for systems that operate in harsh environments.

A hydraulic hose salt-spray test includes the following steps:

1. Spraying the hydraulic hose with a corrosive salt solution.

2. Hanging the hydraulic hose in a closed testing chamber that produces a dense saltwater fog imitating a corrosive environment.

3. Leaving the hydraulic hose in the closed testing chamber for a period of days or weeks, depending on specifications.

4. Removing the hydraulic hose from the testing chamber and evaluating its condition.

If there are no signs of corrosion, the hose passed the test! If it’s rusted or corroded, the material will not hold up in a corrosive environment.

Conclusion

Now, you should understand how often to test your hydraulic hose system and how to do it in order to guarantee safety and capability. By adhering to the recommended inspection and testing frequencies and understanding these testing methods, you can prolong the lifespan of your system, minimize the risk of unexpected downtime, and maintain the efficiency of your equipment. Always consult industry experts or your system’s manufacturer for recommendations or requirements for your hydraulic hose system.
