Hi All,

Please share your opinion. can UT replace RT for tubes subject to furnace radiant heat with diameter below NPS 4 (DN 100) and thickness below 0.5 in. (13 mm). ASME Section I, 2011, table PW-11, general notes (g), requires thickness below 0.5 in shall be RT, while in the table for tubes requires volumetric examination if OD above NPS 4 and thickness above 0.5 in. I have read code case 2235, year 2005, UT can replace RT for thickness at 13 mm and greater.

second question, If tubes has OD below NPS 4 and thickness is below 0.5 in, is volumetric inspection required?

Thanks...
