Hello!
I have a problem dealing with what material to choose as written in the title
I need to urgently purchase materials for full welding stiffener ring on the pipe, while pipe material is SS316Ti.
to reduce delivery impact, I want to change the material of stiffener ring to SS304 or SS316 if possible.
It's the vacuum effluent lead by ejector on vacuum tower and the DP is -970.0 mbarg at 405'C. maximum design temp. is 435'C
is there problem using SS316? I'm expecting to use SS304 as the fluid doesn't contact the pipe, so no pitting corrosion is anticipated for the stiffener ring, I suppose.
any advice will be grateful. thank you.
