Valve disc corrosion - Possibly MIC?
Valve disc corrosion - Possibly MIC?
(OP)
Dear all,
Does this look like MIC corrosion? any ideas?
This was closed all the time. Nothing was flowing trough it.
Only at one spot as you can see in pic 1 I see this smooth corroded surface. The medium was water at room temperature.

I witnessed this with a deep well where the carbon steel bolts of a well pump were eaten away in about 2 years.
