With our humidity and year-round high temps, corrosion resistance and heat transfer are always a concern. These tubes have been performing nicely.

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.

We're dealing with aggressive fluids on the tube side. So far, no pitting or issues.
