Cathodic protection UST

Cathodic protection UST

Cathodic protection UST

(OP)
I have a railcar that we will be burying and using as part of a water cooling system. It is stainless steel and is about 18,000 gallons. Does anyone have tips regarding sizes and materials for cathodic protection for this application. I do not know the soil conductivity yet.

Thanks

RE: Cathodic protection UST

Stainless steel doesn't require protection in most soils.  Also, cathodic current could undo the normal passive oxide film on the SS.  Can we presume 304 SS?

Analyze the soil for salinity (actually, Cl- & F-), pH and anything like sulfide that might feed nasty microbes.

RE: Cathodic protection UST

The first tip is to coat the item with a carefully selected and qualified coating system.  A thermal spray coating may alleviate any need for CP arising from your soil corrosivity assessments.
