There many different types of pressure vessels that can require this type of test periodically to ensure its functionality and safety. A pressure vessel can include anything from plumbing, boilers, pipelines, and gas tanks. Since businesses and homes have some or many of these types of containers or systems, it is important to stay up-to-date on hydro testing.
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.
Since one of the main goals of this test is to see if there are any leaks in the vessel occurring, it is often just called a leak test. This also provides a way to find out where the problem is happening. Hydrostatic pressure tests are also important to examine the general functionality and durability of the pressure vessel.
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 way that the location of a leak is identified is by using some kind of coloration in the medium being used. With water, it is very easy to do this by simply putting a dye in the water and observing to see which direction the water is flowing. Once the area of the leak is determined, it is much easier to see how the problem can be fixed or if the whole thing needs to be replaced.
As soon as a vessel or pipe system like this is made, it undergoes this test to make sure it is safe and up to standards before it reaches customers. Since they can also wear out or malfunction over time, it is also crucial that they are periodically reexamined by a certified professional. A proof pressure test or modified hydrostatic test is usually what they use.
The three main options for mediums to carry out this test with are air, water, and oil. The main drawback of oil is that it is expensive. Air requires specialized machinery in order to set up the test. That is why most professionals offering this service prefer to work with water.
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.
