The standard hydrostatic hose testing procedure is carried out at specific intervals to gather information and determine if an industrial hose, made from either synthetic plastics or stainless steel hose assembly, will be or still is able to perform at the required level of service. The test is required to be performed in a safe and hazard free environment that does not put any employee at risk at any time. The test is carried out at 1.5 to 2.0 of that regular working pressure of the industrial hose, being kept straight at all times and free from boils or bends. The most common material used to perform the test is water but other materials may be used, dependent on the manufacturer’s recommendation.
Prior to initial testing, it is vital to carry out provisional safety checks to provide an environment free from potential accidents or hazards. This is to reduce the risk of causing damage to anyone involved and any property. Because of the potential risks, it is advised that only fully trained personnel carrying the proper tools and test equipment be present and operational during the test. If the testing process requires the use of air or gases, it is highly advisable to contact the suppliers regarding this procedure, as any form of failure may result in a far more serious injury or damages.
Upon preparing the hose for the test (ensuring end connections have been fitted securely at either end of the hose assembly) it should be placed in a straight position and rated at the same pressure as the maximum the very least. You can detect coupling slippage by marking directly behind the fittings at either end. The fittings and connections must also be checked for leakages, if any leakages or damage appears during the test, it is best practice to contact the relevant authorities to dispose of the unusable hose.
If there are no signs of damages, leaks or unnecessary movement, reduce the pressure gradually to bring the testing process through to the final stage. Drain the hose of excess air or water to complete the hydrostatic hose testing. Missing any important details discussed in this overview of hydrostatic pressure testing could cause serious harm, so it is crucial to carry out any and all precautionary measures discussed previously.
