Explanation of Each Test:

1) Hydrostatic Leak Testing requires that a component be completely filled with a liquid such as water.  Pressure is slowly applied to the liquid until the required pressure is reached.  This pressure test is held for the required time at which point the component is inspected visually to locate leaks.

2) Ultrasonic Testing uses sound waves to detect imperfections in material (like steel) and to measure material properties. The most commonly used ultrasonic testing technique is pulse-echo, wherein sound is introduced into a test object and reflections (echoes) returned to a receiver from internal imperfections or from the part's geometrical surfaces are analyzed.

3) An Industrial Radiography Test is a type of NDT.  NDT (Non-Destructive Testing) equipment and consumables enable us to check the structure (and thus the strength) of material without physically taking samples.
