Dear Shadab,
The tube sheet thickness shall be same as job thickness except it does not required more than 50 mm.
In your case you can make a test coupon with 50 mm thick+Weld overlay 10mm.
There are many essentila variables. Refer QW-193, QW-288. in ASME Sec IX.
Regards,
Ibrahim

What should be the range of the Tube sheet thickness minimum and
maximum qualification as per Sec-IX?
Also if i have a corrosion resistant overlay of 10mm on 120mm base
metal, can we use the Corrosion resistant material as a base metal of
same 10 mm thickness for making tube to tube sheet weld joint?
