Hi there!
My vessel need operate at -49°F with MAWP and need operate also at -94°F with a reduced MAWP as per UCS-160. According Fig. UCS-66 is -30°F (SA-516 70N and thickness = 1 in), but the material had impact tested at -54°F, the question is:
What is the MDMT for UCS-66.2 “Step 2” -30°F or -54°F?
Regards.
