Vacuum and Nitrogen testing play incredibly important roles when it comes to securing and guaranteeing the fully functioning operation of your application that makes use of industrial hoses. Each of these testing methods are used for different reasons.
Vacuum testing of hoses is used for suction related applications, whereby it will work to find the faults, if any with your hosing system. The aim of undertaking this type of testing is to ensure you are putting into operation a fully functioning, rigid hose system. It is often used in other ways that are not limited to applications that use high pressure, identifying potentially drastic leaks.
Vacuum testing is an advanced form of testing that tests subject hose assemblies to any negative pressure, reading down to a total vacuum state (-29.92 in Hg - inches of mercury).
A common form of testing for those applications that use water, nitrogen testing allows us to identify leaks through the formation of nitrogen bubbles when the hose is placed and tested in water. The assembly is connected to a test rig via flexible hoses and attached on the other end to a valve that releases the nitrogen slowly and safely. The hose is submerged into water and observed through machinery and gauges to discover any problems.
When the test time has been completed, the hose assembly is released of pressure in a safe and controlled manner, before having results recorded and then sent to the customer, notifying of any issues that may have been identified.
These types of testing are some of the most effective methods to ensure that your applications are running in the smoothest and secure manner, immediately identifying if there are any problems in the form of leaks, breakages and other malfunctions.
