[MW:25463] Stress Value of SA-240 TP 316 Ti For SA-213 (seamless) tube & SA -312 (seamless) pipe thickness caculation

Dear Experts

Since the stress value of SA-213 (Seamless Tube) TP 316 Ti and SA-312 (Seamless Pipe) TP 316 Ti are not indicated in ASME Sec. II-D.

　

As per UG-15 provisions, can we use SA-240 (plate) TP 316 Ti stress value for calculating the tube and pipe thickness calculation. However Tube and Pipe of TP316Ti will be procured based on ASME Sec II-A specifications ?　

I have investigated one old code case record number- BC88-182 which has similar kind of query.　

Further I have also found new Code case 2849, Approval date 1-20-2016 'Use of Austenitic Stainless Steel SA-312/SA-312M Type 316Ti (UNS S31635) in the Construction of Heating Boilers', which may be resembled with my query case.

However right now I am not having copy of the same.
