316L wharf pipework corrosion
316L wharf pipework corrosion
(OP)
Approximately two years ago we installed a diesel refuelling line fabricated from 316L which runs under an existing timber wharf approximately 1meter above the high water line. On a recent inspection, red staining and areas of corrosion were noted along the length of the pipe only on the sections under the wharf. Does anyone have any idea what would cause this?

All with have is photos to go by as the site is remote, but there does appear to be a small degree of pitting in places.

Any iron from hangers,fastners, etc. that gets on the pipe would help Metalguy's bugs gain aquatters rights.
As he notes they are insidious as a small pitted area will lead to a condominium.
You didn't say whether the line is 1 meter above salt water or fresh water. I assume saltwater as you used the term wharf. 1 meter is in the splash zone, the actual worst place to have a piece of S/S.
The line needs to be inspected closer to determine exactly what going on.
