Hydrostatic Pressure TestingHydrostatic testing is an incredibly beneficial means of detecting a fault of any size within an industrial hose. This non-destructive pressure testing method is commonly used throughout a vast range of industries and productions. The main purpose of a hydrostatic pressure testing is to search for any potential damage that can disrupt workflow such as cracks, leaks or irregular changes in shape. Despite the test being deemed non-destructive, damage can occur to the industrial hose if there is a major problem that is worsened with the added pressure.

This obviously means the hose does not meet the required specifications and will be removed from production immediately.

The testing process will more often than not consist of adding water, air or helium to the pipe at a rate of pressure that is at least 1.5 times greater than the standard working pressure, to ensure the hose functions correctly and efficiently even at a pressure greater than normal. The benefits of using water for the testing process is that it is far more cost effective than materials such as oil and also has many benefits, such as usually being safer and providing a testing facility when using air for the test (with the hose being placed underwater).

The most commonly used measurement for a non-destructive pressure test on industrial hoses is PSI (pound per square inch). The measurement of PSI that a standard hose can reach will always be greater than its operating pressure to provide the industry with a margin for safety. The results of the testing will depend on the condition of the industrial hose and what it will be used for. For example, if even the smallest leak is detrimental, the hose will be tested with helium as the molecules are much smaller than water and air and able to detect leaks on a molecular level.
