Pneumatics Testing: All You Need To Know.
Most of us use equipment and tools that require the induction of pressure for them to function. For this reason at one time or another you may require to crosscheck if the amount of the pressure in the same is as required. This is because failure to do so might result to various problems even to the breakdown of your equipment.
A pneumatics testing in thin case is a test that is carried out to verify the amount of pressure in a system.
However, there are several other methods that are used to carry out pressure tests on the systems of various equipment but the pneumatic test is the most used.
The equipment that is used to carry out this test is gauges and for the gauges to work promptly there has to be a source of compressed gases.
What is a Hydrostatic Test?
It is important to note that in the case of pressure testing, if the fluid that is used to apply pressure on the system is a liquid then the test is referred to as a hydrostatic test.
Pneumatic tests are carried out only when he fluid being used in this case is liquid gas. The process of the test is simple since all one has to do is to close or entrance and exit points of the system leaving only one opening. In this, the fluid is added until the pressure rating of the system is achieved. A pneumatics testing can also enable one to identify if their systems are faulty sine if the system has a leak the pressure will not be achieved as the fluid will be coming out from the leak area.
Is Pneumatic Testing Safe?
Most pneumatic tests are dangerous due to the high energy levels of compressed gas. It is more safe to use a hydrostatic test in the case that the system is prone to very high levels of pressure. However a pneumatic can be conducted smoothly in the systems that are of low pressure content. It is important that you are very careful while conducting the pneumatic test as there might be an explosion due to excess pressure levels. This may lead to very serious injuries to the individuals who were near the system at the time of testing.
Due to the danger of the pneumatics testing, it is widely used for the testing in piping vessels.
Here the individual carrying out the test must avoid completely the induction of moisture.
- Most of the accidents that occur during pneumatic testing are due to:
- shock waves while inducing pressure into the system,
- fragments that are flying from the ruptured piping system
- and unrestrained movement of the pipe as the test is carried out.
Most companies are tasked with the aim of reducing the accidents and injuries that occur when using the test systems. However in the case of limiting the pressure in wider pipe it is almost close to impossible since the size of the same presents a major challenge for this to be achieved.
There are concerns but testing is always important.
