Dear Experts, Could you please advise, whether PAUT is recommended lower thickness (Dia 2inch X 4 to 5.5 mm thick). As i knew that below 6mm not recommended for the PAUT according to ASME Case 2816.     Thanks & Regards,  K.GANESAN 

If you are decreasing pre-heat tepm. More then 55c it will be essential variable. In this this case you need re-qualification.
