OnGuard Top 8 Reasons Hydraulic Hoses Fail

Top 8 Reasons Hydraulic Hoses Fail

There are numerous reasons why a hydraulic hose can fail. More often than not, the most common failures are ones that could have been avoided with proper precautions. At Texas Rubber Supply, we utilize OnGuard Hose Safety to work closely with customers and educate them on how the program helps you avoid costly equipment downtime, maintenance costs and reassure you that your hoses are working efficiently and safely — all within compliance of OSHA/EPA standards.

1. Tube Erosion

Hydraulic hose tube erosion often causes external leakage. Tube erosion is typically caused by a concentrated high-velocity stream of fluid or by small particles in the fluid.

2. Fluid Compatibility

System contamination and external leakage can be a direct result of fluid incompatibility. Incompatible fluids will cause the inner tube of the hydraulic hose assembly to deteriorate, swell, and delaminate (divide).

It is important that you make sure that the hose you order must be compatible with the fluid being moved. It is also important to make sure that while the fluid is compatible with the inner tube of the hose, that it is also compatible with the outer cover, fittings, and even O-rings as well. To ensure that your medium is the correct one for your hose, please check OnGuard Asset Management’s Chemical Resistance Chart for hose.

3. Dry Air / Aged Air

The inner tube of hoses can develop numerous tiny cracks due to aged or dry air. This type of hose failure is sometimes hard to spot because your hydraulic hose will still remain flexible. Typically there are no signs of cracking on the hose under the fittings.

To avoid aged or dry air problems, confirm that your hose is rated for extremely dry air. Hoses that have inner tubes of PKR or EPDM rubber are preferred for these specific applications.

4. Minimum Bend Radius

Hose assemblies can fail relatively quickly if the minimum bend radius is not met.

In vacuum or suction applications, for example, if the bend radius has been exceeded the hose may tend to be flat in the bend area. This will hinder or restrict flow. If the bend is severe enough the hose may kink. To prevent bend radius hose failures, double check the recommended bend radius. Replace hose assemblies and change routing, length, or fittings to route the house within the published minimum bend radius if they do not comply.

5. Insertion Depth

When a hose assembly is not properly assembled, it can create very dangerous situations. Fittings need to be pushed on completely to meet the proper insertion depth. If insertion depth is not met, fittings can blow off and leave a failed hose assembly behind. The last grip in the fitting she is essential to the holding strength of the hose assembly.

6. Improper Assembly

Contamination can cause several problems for a hydraulic hose assembly. If not properly flushed, metal particles and debris can settle inside the hose. This abrasive debris left inside the hose will contaminate the hydraulic system. This contamination can also cause small fractures to occur on the inner tube of the hose assembly, resulting in leakage.

To prevent hose failures from contamination, the hose must be properly cleaned before inserting the fittings. The inner tube should be “squeaky-clean” before fittings are inserted. After the fittings are crimped, be sure to cap the ends in order to keep the hose clean and avoid recontamination during transport.

7. Heat Aged

Overheating a hose assembly can cause hose failure by causing the hose to become very stiff. The inner tube hardens and begins to crack because the plasticizers in the elastomer will break down or harden under the high temperature.

In some cases, the cover may show direct signs of being dried out. The hose assembly may remain in its installed shape after being removed from the application and if flexed, an audible cracking can be heard.

To prevent overheated hydraulic hose assemblies, confirm that hoses are rated for the temperatures required by your application. Also, reduce ambient temperatures or use heat guards and shields to protect the hose from nearby high-temperature areas.

8. Abrasion

Hydraulic hoses are put through rigorous applications every day, which eventually take their toll. If not inspected on a regular basis, abrasion can cause a hose assembly to burst or leak.

The cover of your hose is meant to protect it. So signs of damage to that cover or reinforcement layers should warn you that something is wrong.  With a little background knowledge and training, many hose failures can be prevented.

OnGuard Hose Safety offers hose safety training and hose product seminars on a regular basis. We know you can’t afford the downtime at factories by traveling, so we often provide safety training on-site at customer designated locations.  We train staff from every department including maintenance, engineering, safety/environmental (HSE) and manufacturing teams.

10 Hose Handling and Maintenance Tips

On-Site and In-House, OnGuard Hose Management services are tailored to customer needs. We create person to person relationships and programs tailored to address the needs of a customer to lower procurement costs, maximize productivity, create a safer work environment and/or manufacture a safer product.

Check out the below 10 tips on proper hose handling and maintenance

  • Never exceed the rated working pressure of a hose.

    •  Never allow pressure spikes or surges above the maximum rated working pressure of the hose
    • Excessive pressure can shorten the life of the hose
  • Never run over a hose with equipment or vehicles, such as forklifts.

    • Running over a hose can damage the tube, reinforcement, and cover
    • A buildup of pressure can cause damage at the coupling
  •  Never pull a hose by its coupling

    • Pulling a hose at the coupling can kink the hose and weaken the coupling’s bond to the hose
  •  Never lift a heavy, large-diameter hose by the middle with the ends hanging down.

    • The internal reinforcement can be damaged at the support point
    • Support large hose every ten feet with rope saddles or slings
    • When moving a hose, always lift the hose and coupling together
    • Use dollies, rollers, or derricks when moving large hoses
  •  Never over-bend a hose to the point of kinking

    • Never bend the hose tighter than the recommended minimum bend radius
    • Never kink a hose to stop the flow of material
    • Kinking a hose can seriously damage the tube and reinforcement
    • If needed, install bend restrictors at the coupling to prevent the hose from being bent past its minimum bend radius
  • A hose cover exposed to excessive wear can be protected with an extra cover, such as a nylon sleeve or pad.

    • Make the cover slightly longer than the hose to accommodate any change in the hose length when in use
  • Remove kinked or crushed hose from service immediately

    • Inspect and test the hose before putting it back in service
    • An outside diameter of a hose which has been permanently reduced by more than 20% should be removed from service
    • An outside diameter of a hose which has been reduced by 20% or less should have a hydrostatic test done before being put back into service.
  • Remove and test any hose assembly that has been subjected to abuse

    • This includes a hose that has been severely pulled at the coupling, flattened, crushed, kinked, cut, abraded or exposed to temperatures or pressures above noted maximums.
  • Visually inspect and pressure test hose at regular intervals

    • This is extremely important for critical application hoses, such as acid/chemical, steam, LPG, and petroleum
    • Check for kinks, bulges, soft spots, loose areas, abrasions, and cuts
    • Cuts or abrasions which expose the reinforcement are signs that the hose should be immediately removed from service
  • Always check for fluid seepage by pushing at the base of the coupling with your thumbs; a hose softened by fluid seepage must be replaced

    • Check for coupling slippage
    • Remove any hose that does not pass your visual inspection
