: Mehmet Bey,
: According to ASME-V article-2 T-276 (a) The thickness on which the IQI is based on the nominal single wall thickness plus the estimated weld reinforcement….. Actual weld measurement of the weld reinforcement is not required.
: So in your case (10.31 mm) you can use set B type of panateremeter.
: Regrads,

: : Can any one answer the following: 2 inches but weld is radiograped eliptically. The wall thickness is 8.71 mm and weld reinsforcemnt is 1.6mm. In accordance with ASME-V article-2 T-276 what will be the thickness that the penetrameter based on. In another way the thickness that the penetrameter based on will be (8.71mm+1.6mm=10.31mm) or (8.71mm+8.71mm+1.6mm=19.02mm)?
: : Looking forward to have your answer with appreciation.
: : Many Thanks in advance

I would like to add my opinion on this issue. This has been debated often in the past. The correct thickness for your shot is the single nominal wall thickness plus the maximum reinforcement allowed by the referencing code section. In your case you have 1.6 mm on the face and 1.6mm on the root. Therefore, your correct thickness is 11.91mm. I have an interprepretation on this by ASME B31.3 code comittee which clearly states the height of reinforcement is for each face of the weld and can be added together when determining penetrameter requirements for radiographing girth welds.
