how often should hydraulic hoses be changed

Hydraulic hoses are an essential component of any hydraulic system, responsible for transmitting fluid from one component to another under high pressure. They are designed to be durable and withstand harsh operating conditions, but like any mechanical part, they do eventually wear out and fail. Knowing when to replace hydraulic hoses is critical to maintaining the safe and efficient operation of your equipment. In this article, we will discuss how often hydraulic hoses should be changed and what factors can affect their lifespan.

Factors Affecting Hose Lifespan

The lifespan of a hydraulic hose depends on several factors, including the type of fluid being transported, operating temperature, pressure, and abrasion. The following are some examples of how these factors can affect the lifespan of hydraulic hoses:

Fluid Compatibility

Different hydraulic fluids have different chemical compositions, and some are more corrosive to hoses than others. The most common hydraulic fluid is petroleum-based oil, which is generally not corrosive to hoses. However, if your equipment operates with a more aggressive fluid, such as phosphate ester or water-based hydraulic fluid, it can cause hose degradation, resulting in shorter hose life.

Operating Temperature

Temperature plays a significant role in the longevity of hydraulic hoses. Hoses that operate at higher temperatures tend to fail faster than those that operate at lower temperatures. This is because high temperatures can cause the rubber compounds in the hoses to break down, resulting in cracking and leakage.

Operating Pressure

Hydraulic hoses are designed to withstand high pressure, but each hose has its pressure rating. If the operating pressure exceeds the maximum working pressure of the hose, it can result in damage to the hose, including leaks, bulges, and bursts. Overpressure events can also cause hose fittings to fail, which can lead to sudden hose detachment, resulting in potential injury or equipment damage.

Abrasion

Abrasion is another factor that can contribute to hydraulic hose failure. If hoses are constantly rubbing against other parts of machinery or if they are subjected to sharp or abrasive surfaces, they can experience premature wear, cracking, and punctures. Heavy equipment or machinery that is used in harsh environments, such as mining or construction sites, is especially susceptible to abrasion-related hose damage.

How Often Should Hydraulic Hoses Be Changed?

The frequency at which you must replace hydraulic hoses depends on several factors, including the lifespan of the hoses, the frequency of use, and the severity of the operating conditions. It is recommended that hydraulic hoses be inspected regularly for signs of wear and tear, such as bulges, cracks, or leaks. This can be done during routine maintenance procedures, such as oil changes or filter replacements.

From our experience, hydraulic hoses can typically last between five and ten years, though it is possible for them to fail sooner. However, the frequency of use and the severity of operating conditions will affect the lifespan of hydraulic hoses. Heavy equipment or machinery that operates in harsh conditions may require more frequent hose replacements, whereas equipment that only sees minimal use may have a longer lifespan.

Conclusion

Hydraulic hoses are essential to the operation of many types of heavy equipment and machinery, and their performance is critical to ensuring that your machinery operates safely and efficiently. Knowing when to replace hydraulic hoses is crucial to keeping your equipment running smoothly and preventing costly downtime. Proper maintenance, regular inspections, and recognizing the signs of hose failure can all contribute to extending the lifespan of hydraulic hoses and minimizing the risk of hose-related equipment failures.
