Generally we give marking as RT-1 only with a note in Manufacturer's
data book (MDR) that UT for so and so seams was carried out in lieu of
RT.

Dear Raghavendra
Since you are using CC2235, I have a doubt on Name plate marking as per
UG116 for div 1 vessels. In case when a portion of the vessel RT**ed as
per UW11(a) and the remaining portion UT*ed per CC 2235 in lieu of RT,
what will be the marking, is it RT-1?

Dear Rohit and Raghuram,
Thanks for the information related to Codes,standards and
Specifications.
Our Organisation has obtained 'N' Stamp from ASME during last year and
once the nuclear treaty is signed between India and USA, we have got
bright chances to get orders for manufacture of Nuclear power related
Equipments from abroad.
As we could successfully replace RT by UT as per CC2235 incase of
Sec.VIII vessels, I want the same trend to continue in case of Sec.III
of ASME as well, which are expected in future. But all nuclear new
construction codes of ASME are strong believers in Radiography. I am
looking for a hint to extend TOFD on nuclear new construction also.
That is why my query related to the same.
Hope I could convey.
regards,
Raghavendra
