Why rubber hose failure happens?

Rubber hose has been regarded as vital elements for hydraulic systems. Due to its great flexibility, hydraulic hoses make the hydraulic system compact and effective. According to pressure gratings, they are usually divided into four types - low, medium, high and super high.

Hydraulic hose has a predictable future and routine maintenance is very important. However, in specified applications, hydraulic hose failure is frequently happened. How to avoid the failure to avoid incidents should be paid much attention to.

Our engineers have summarized seven reasons of hose failure. Hope they can help you solve your problems. If any question, don't hesitate to email us and you will get professional reply.

  1. Improper routing.
    Improper routing including flexing the hose to less than specified minimum bend radius often cause leakage or deformation. To maximum hose long service life, choose appropriate clamps and place them in the right place.
  2. Exceeding specified working pressure.
    Any type hose has its working pressure. Once the working pressure exceeding its specified data, the probability of hose failure will substantially increase.
  3. Pressure surges.
    Surge pressure surpasses maximum operating pressure. When hoses are exposed to surge pressure, hose life will be certainly shortened. If the surge pressures are much higher than specified working pressure, select a hose with spiral wire construction.
  4. Excessively high or low operating temperature.
    Excessively high or low temperature will degrade the rubber and limit hose's usage finally. Hoses continuously work at maximum temperature should be avoided. This will cause rubber deterioration and accelerate hose failure.
  5. Ambient temperature.
    Ambient temperature will affect cover and reinforcement materials, especially in hot media conveying. If you are confused about it, consult our on-line service or email us directly.
  6. Chemicals and other adverse factors.
    Chemicals including oils, fuels, acids and alkalis and cleaning solvents will affect the performance of hose cover, o-rings and fittings.
  7. Improper fittings.
    One fitting doesn’t fit all hoses. When selecting fittings for your hose system, either crimped or reusable type should be decided before installation.
