It's hot and humid here, and our old wrap-on tubes used to rust like crazy. Switched to your extruded ones—the aluminum fin covers the steel pipe perfectly, so corrosion shouldn't be an issue.

The 13Cr pins add some cost, but for sour service in furnaces, it's worth it. Already seeing longer run times between turnarounds compared to before.

With high firebox temps and some sour gas in the mix, regular carbon tubes don't last. These have been solid.
