Almost everyone has encountered a pressure vessel in their life, although some people don't know them by this name. They come in many forms and sizes, and are used for a number of different things in people's houses and businesses. Things like plumbing, pipelines, gas tanks, and boilers all need to be check with hydro testing in order to keep family member and employees safe, and for the container or pipeline to work properly.
These vessels are built and designed to be able to hold pressurized gasses and liquids and very high or very low temperatures. Early vessels had problems that lost many people their lives over the years. Safety is a big concern for the manufacturers and inspectors of these containers.
A test of a pressure vessel's hydrostatic pressure, also referred to as a leak test, is a way of identifying if there are any leaks or other issues. When there is a leak, the test is designed to figure out where and why the leak is occurring. This is also a way of checking to make sure a vessel is durable enough and that it is functioning correctly.
The way this test works is by filling up the container or pipes with water or some other liquid. Water is usually preferred because it won't damage the system. Depending on what type of vessel the test is being performed on, it will be filled to a specific pressure, and the tester will check to see if any of the pressure is lost after the supply valve is shut off.
The best way to tell where a leak is happening is by adding some kind of coloration to the medium being used. This is easily achieved in water with dye, which is the method many testers use. By simply following the dye and seeing where it is escaping from, sometimes a problem can be solved easily where it would've seemed like a major replacement was due.
Now that these tests are standardized and required of all vessels, manufacturers will have them tested directly after they make them. This means that customers can be assured that the container or pipe will work correctly and not put them at risk. Tests that are done periodically are called modified hydrostatic tests, also known as proof pressure tests.
Customers will often get to choose which medium they would like to use for their system's test, but professionals will most often recommend water depending on what type of pressure vessel it is. This is because water works best for most of these, and is by far the least expensive. Oil is costly, and air requires special equipment in order to set up a test for it.
It is necessary to make sure that a pipe or vessel can withstand pressure that is much higher than what it is expected to operate at on a normal basis. This is because extreme conditions sometimes do occur and mistakes are made. By performing the test at a percentage above normal pressure, there can be a margin for error.
