Which NDT method to choose?
Which NDT method to choose?
(OP)
Is NDT necessary for all relief valves in oil gas application? Why is it only done for relief valves?
How do you decide which NDT method should be used?
In the spec it says 'ultrasonic examination (UT) as an alternative to radiography for forgings will be accepted for Classes 300 and above', does it mean for class 150, ONLY radiography testing should be done?
A supplier offered liquid penetrant examination, is it acceptable?
Thanks..

Radiography(RT)is used to look for defects in the casting or forging material. UT would be nessecary when the component thickness is increasedbeyond where RT becomes impracticle.
