The list is truly endless for industries that require the daily use of industrial hoses. These hoses are used to transport various materials safely and securely. These materials can include liquids, solids, gases, harsh chemicals and medical chemicals. Any industry using hoses on a daily basis will undoubtedly require these hoses to perform as expected, requiring an efficient workflow to deliver certain materials or products on strict deadlines. Even the most minor disruption to workflow can have serious repercussions. That is why all hoses and hose assemblies should be checked visually and via specific hose pressure testing methods to ensure the continuous and consistent delivery of materials and products.
An industrial hose can become damaged from the outside in a variety of different ways. A visual inspection can detect the more obvious signs of stress such as dents, leaks, kinks and cracks. Any small defect that is barely noticeable, or may be brushed off by some as irrelevant, can be a total disaster waiting to happen. As well as a general visual inspection, the hose assembly will be inspected internally as well. The failing of the internal structure from even the smallest imperfection can cause a major disruption to the efficiency of the daily workflow and production, making both the external and internal visual inspections crucial.
Hydrostatic pressure testing is a more detailed procedure that detects issues by pumping a hose assembly full of water, taking it to a very specific pressure during the test (roughly 1.5 times the maximum working pressure). The results taken from a hydrostatic pressure test are based on its integrity being maintained during the higher pressure.
Another incredibly effective testing method for detecting issues within hose assemblies is with a helium test. The molecular size of helium allows the test to discover even the smallest leak or crack that may become an issue in the future. Despite the effectiveness of other hose pressure tests, the larger molecular structure of other pressure testing materials simply cannot detect those smaller defects.
Hose pressure testing is vitally important for industries that use hose assemblies on a daily basis for manufacturing and production purposes. It is essential to conduct regular tests as preventative measures against the disruption of workflow.
