Minimum Thickness for UT

Dear Friends,
What is the minimum effective thickness for UT of welding in pressure vessel by Angle probe (single crystal) and common portable flaw detector?

Re: Minimum Thickness for UT
Please refer ASME Section V, Article-4 and 5.

Practically I limit myself to 10mm as a minimum thickness and I prefer to use 80 degree shear wave probe along with usual 70 degree probe for 10mm thickness.

AWS D1.1 states 8 mm as a minimum thickness and any weld less than that may be tested using specific test procedure established using sufficient number or mock-up welds of same thickness containing anticipated type of defects at various depths.

Regards,

Re: Minimum Thickness for UT
Dear Mr.Amiri,
From 8mm you can do UT by angle probe with single crystal.

Re: Minimum Thickness for UT
Gents,
UT - Make your equipment and your mind equipped before carrying out UT on particular job.
Quantify yourself whether your equipment & setup is capable to test the minimum requirements. for that u have to use calibration blocks, refernce blocks (with refernce to your job u r going to test), make a 1:1 diagram, equip your mind...
now it is practically possible to go for minimum thicknes and even complex geometry UT inspection.
