Dear All ,
Is there any minimum thickness limit specified in any code for the
tubesheet plate UT check to be carried out.
Normally, almost code did not mention about min thickness limit.
But so far, you can refer AWS D 1.1, 6-Part F: "For thicknesses less than
5/16 in. [8 mm] or greater than 8 in. [200 mm], testing
shall be performed in conformance with Annex S", you can refer Annex S in special case. So, in normal case, min thickness is 8mm.

Or other code you can refer: EN1712 (EN 11666) limits the checks welds to 8mm; EN 10160 limits to 6 mm the plates control; ISO 12094 go down to 4 mm
