Valve NDT Test - UT/RT/PT?
Valve NDT Test - UT/RT/PT?
(OP)
Hi,
I am new in valve industry, i have a lot confusion on the NDT test (UT/RT/PT). In what situation shall we carry out the correct NDT method?
I understand my company that:
1. We dont carry RT on forging valves.
2. We dont carry UT on Casting vavles.
Can anyone give your opinions? what are the limitations of each NDT test?

The limitation is given by the market you want to sell to. Market research requierd. What do competitors do, what does endusers require, what is common? (A valve is not a valve).

RT and UT are volume examinations. While you can use either method ASME B16.34 has the primary method of examination for castings as RT and Forgings as UT.

Thank you. the information is very helpful. BS16.34 does define the applications of surface examination, i will go back and read through it.
