AL fin severe distortion
AL fin severe distortion
(OP)
Now, we found severe distortion at AL fin of finned tube of the air cooler heat exchanger. (In my experienced, i'm never found this problem before)
Is this cause by heat that exceed AL temperature limit?
Anyone experience this issue, please advise.
Thanks for any help

Chicopee and Ron; We can confirmed that this is not caused from accident. from the day one of operation it look very good condition and then 9 years of operation it look like in the picture.
Edstainless: Now, we try to verify the type/ grade of AL fin to find the temperature limit.

Pressure washer?
RE: AL fin severe distortion
If the unit were running very hot (over design) and then cooled fast you could start buckling the fins.
But I am with MJ, has this unit ever been washed?

This exchanger is placed on the Platform, Offshore installation and cleaned by HP water in some shutdown period. (Very rare)
I will check with production team for the exact cycle of thermal cyclic.

I have never seen it look exactly like the posted photos, but it is a possibility.
