Not only in the field of oil and gas industry but also in every other field of interest that there exist physical components and moving parts, mechanical engineering plays a major role. Specifically, in the oil and gas industries, mechanical engineering is the most vital major that carries the heaviest burden while there are structures, machines, instruments, and a lot of other types of equipment working together under heavy loads in harsh environments.

According to this, inspections are necessary to check the condition of equipment and make sure everything is working safely and properly. Therefore, due to the existence of critical and complex components, skillful inspectors are required to check the conditions and take proper actions.

During an inspection, tests should be performed to examine the condition of facilities. Usually, we can classify tests into w main categories:

• Destructive tests
• Non-destructive tests

Destructive tests:

During destructive testing, a specimen will undergo test procedures that at the end of the process the specimen is no longer intact and irreversible damages have been done to it. This type of test is usually done to find the properties of the material and if it still maintains its suitable properties.

Non-destructive tests:

In contrast to destrctive testing, this type of inspection uses a variety of methods that can detect flaws and inconsistencies without harming the object.

ultrasonic testing, radiographic testing, magnetic particle testing, electromagnetic testing, and many more are some of the examples of NDT.
