The chloride ions in the shell-side medium are 180,000ppm, and the tube-side medium has no corrosion. What material is good for the tubes and shells?

The heat exchanger tube bundle, the shell side medium is crude oil, the chloride ion in the medium is 180000ppm, the tube side medium is heat transfer oil, no corrosion, what material is better to use? Domestic anti-corrosion measures are estimated to have limited capabilities, so we try to use suitable materials and ask for advice from experts.
How to take chloride ion anti-corrosion measures? I’ll give you a link, go check it out! http:// * * /BBS/thread-116960-1-1.html has been fixed! This post was last edited by prt0683 on 2009-4-12 22:25 ]
The shell-side medium is in contact with the outer walls of the shell and the heat exchange tube, so both have strict requirements. In addition, why is the Cl content in your crude oil so high? What is the reason? I think 20# steel pipe will do!
Chloride ions are highly corrosive to stainless steel. If the concentration is not too high, 20# steel should be fine.
Stainless steel is definitely out of the question. The chloride ions in your shell-side medium are 180,000 ppm. Although the tube-side medium is heat transfer oil and is non-corrosive, the medium will contact the shell side and the outer surface of the tube, so the tube and shell sides also have anti-corrosion issues, and factors such as temperature and pressure must also be considered.
