When you have to test operational quality of different pressure units or pipe systems, there are several different techniques. One of the most commonly used processes is hydro testing. It is used every time when system was out of order for some time, for repairing or for any other reason, or as a regular checkup of different systems and pressure devices.
This is fully nondestructive testing that will check the performances of particular unit. It can be done only when this equipment is not running and the system is shut down. The whole point is to check the unit for any leaks or other flaws that may cause the failure or need any type of repairs before placing the equipment into normal operating state.

When it comes to different pipelines, the system should be first totally emptied, and all natural gas, oil or other substances removed. After that, the pipeline should be mechanically cleaned and vented. The whole system is then filled with water, and this process removes all the remains of air held within. After that, the pressure that exceeds the designed pressure limit of this pipeline is applied.
For this particular procedure, the pressure that exceeds the normally used pressure by 50 percent is used. Once under exceeded pressure, the pipes should be visually checked for possible leaks and other problems that may occur. Fluorescent dyes are also used in some cases, where it is important to find the origin of the leaks or various cracks in the structure. The use of dyes makes all this much easier.
Once everything is checked, the water leaves the pipes. It's important to vent the pipes and that they are perfectly dry before they can be filled with oil, gas or whatever they suppose to carry. The water may cause corrosion, and needs to be removed entirely. Different liquids may have different properties.
When it comes to small pressure vessels and cylinders, different procedures are used. There are three main testing methods, depending on the equipment that has to be tested. The first one is called the direct expansion, and in this procedure, the unit is filled with certain amount of water and pressured for certain amount of time. The water expelled from the vessel is measured after that.
Water jacket method is called so because the unit, after being filled with water, should be loaded into a sealed test jacket. Once the vessel is in this sealed chamber, it's put under pressure, and this pressure forces water o

Water jacket method is called so because the unit, after being filled with water, should be loaded into a sealed test jacket. Once the vessel is in this sealed chamber, it's put under pressure, and this pressure forces water out from the chamber, into the glass tube. The amount of water that gets expelled is the measure of the total expansion.
When this process is over, the vessel should shrink to its original size. If it doesn't shrink back totally, the difference between sizes will tell you if the vessel needs the service. The pressure method is used in cases when measuring this difference is not so important, or required by various laws. In this case, the unit is only checked for leaks or wall thinning that may be causes of failure.
