API 6A Flanged Gauge PSL1 to PSL3

[michaelp8]

Hi all. If I purchase a flanged pressure gauge as a PSL1 and want to convert it in house to a PSL3 by NDE testing, is this possible? I am assuming that if I obtain all the necessary MTR's with the gauge then I can convert in house.

Anyone?

Thanks

i think no.
PSL3 demand UT or RT at raw material stage.
you can conduct this test but you still can't assign PSL3 on it.

another constraint....
you can assign this to PSL3 directly unless you saw MTC has UT/RT at raw stage.
sometimes i see some material with PSL3 qualification being downgrade to lower PSL.
