A Hydraulic hose is a style of industrial hoses. There are lots of reasons which can lead to an early failure of hose assemblies, and operators should be aware of these – including improper hose routing, and just using them wrong! If you’re wondering how long they should last – this is hard to determine, as it all depends on its usage and the conditions its exposed to. Industrial hoses should be checked often.
Hoses that are exposed to high levels of heat or extremely cold temperatures tend to break down faster than hoses at an average room temperature. If you need to use a hydraulic hose in such temperatures, there are specific compounds used in the manufacturing process of some hoses which can postpone the effects of these conditions. Alternatively, you could get protection covers for your hoses that can help protect it from abrasion, sparks, and metal splash in some industries. However, under these conditions, hose covers are only delaying the inevitable.
Improper Hose Routing
One of the main reasons for industrial hose failure is improper routing. This causes unnecessary stress and abrasion on the hose. If there is extra stress placed on a hose assembly that is improperly routed – it will lead to failure. This usually occurs where the fitting is crimped, towards the end of the hose assembly.
Another thing to consider when keeping on top of your hoses, is their usage. A hose that is being used as part as commercial earth moving equipment for 40 hours a week would need more attention and management than a hose which is being used on consumer grade equipment for only a couple of hours a month. If you frequently check your hoses on high-use equipment, you can catch any problems just as they start occurring and get them resolved. This can prevent any stoppage caused by full failure.
The inner tube of hoses can develop loads of tiny cracks from dry or aged air. This failure can be difficult to spot as the hose won’t be cracked on the exterior, and will remain flexible. Still, if this has occurred there will be signs of leakage. To avoid this problem, you should check if your hose is rated for dry air. Hoses with PKR or EPDM rubber inner tubes are best for this, or if possible, raise the dew point of the environment.
