Hi Firend
P/Array is reliable method can be used in liu of RT and very fast and no hazard
However you should have instrument and qualified person to carry and interprete the process
There are NDE/NDT vendors who take up the NDE by P/Array However you require to qualify the mock up prior to NDE test depends upon thk,Metallurgy etc

Dear Experts,
Can you please guide me regarding PAUT (Phased Array Ultrasonic Testing) instead of RT. Our contractor has recommended PAUT due to RT process is slow and it will be affected the project schedule. So, they are pressuring us to do PAUT instead of RT.
Is it good NDT technique & which standard shall i follow for the acceptance criteria.
Please share the testing method and acceptance criteria, if anyone have.
I'm waiting for your valuable advise in this regard.
