Previously, we discussed the acronym S.T.A.M.P.E.D. This acronym is short for Size, Temperature, Application, Material/Media, Pressure, Ends, Delivery.
Today we will tackle the next letter, “A,” that represents Application.
At first, “application” might seem like a broad term in regards to choosing the correct hose for the job, but it really isn’t. “Application” refers to the environment in which the hose will be exposed to. Exposure can mean anything from what is being conveyed through the hose, to external exposure to other chemicals, ozone, or other harsh environments.
How the Environment Affects Hose
For instance, in a steel manufacturing plant, you might need to protect the exterior of a hydraulic hose from molten splash caused by the manufacturing processes that occur in a steel mill. Without discussing some of the harsh environmental challenges, a hydraulic hose without the correct external protection is a failure waiting to happen.
Another example of “application” would be a high abrasion area for a hydraulic system. We see this a lot of time in the field with mobile hydraulics, such as small bulldozers, excavation equipment, and sanitation trucks with hydraulic arms that are constantly extending and contracting. Without a stronger external cover, these hoses will fail quicker than if the correct hose was used for this application.
Sometimes hoses, both hydraulic and industrial, will need to be routed through a tight turn and the bend radius of the hose will be a factor in choosing the right series of hose. This is one of the reasons we will ask customers as many questions as we can – to ensure they get the exact hose they need for their application.
Such questions are:
- How did the previously installed hose perform?
- Did the hose assembly fail because it was incorrectly spec’d?
- Did the outer cover fail prematurely due to environmental stressors?
- Could these have been prevented if the correct hose was used for this application?
- What regulations might dictate what hose we’d recommend? (FDA, USCG, etc)
There is a multitude of situations and conditions that must be considered to correctly and safely spec a hose. In some applications, there might be a need for a static dissipative hose to prevent the buildup of static electricity. It is up to us as hose professionals to ensure the hose we recommend is up for the job and will keep you safe – every time.
