Radiographic Testing (RT) is a non-destructive testing (NDT) method which uses either x-rays or gamma rays to examine the internal structure of manufactured components identifying any flaws or defects.
In Radiography Testing the test-part is placed between the radiation source and film (or detector).
Ultrasonic testing is done in materials to determine whether there are flaws or defects present in a material, and also to determine the thickness of a material.
Ultrasonic testing methods use sound waves to find defects and measure thickness.
Liquid or dye penetrant testing (PT) is a non-destructive material testing method which uses capillary forces to find surface cracks or pores and make them visible.
It can detect surface-breaking flaws such as cracks, laps, porosity.
A hydrostatic test is a pressure test in which the pipe or other component is pressurized to evaluate its integrity.
This test is used to evaluate the structural integrity of pipeline or other pressure containing infrastructure.
