Subject: [MW:25859] R-stamp
We have one Vessel to fix baffle plates . Vessel is under service since 9 years. Shell thickness is 38 mm and baffles plates thickness will be 7mm. My question are:
1. Is R-stamp required or not? 2. Is local PWHT required or not?
Please share / send me answer with reference of codes
Thanks and Best Regards
