Stainless Steel Pipe on Galvanized Steel Supports
Stainless Steel Pipe on Galvanized Steel Supports
(OP)
Are there any concerns about laying stainless steel (types 304 and 316) piping systems directly on galvanized steel supports in a high humidity, US Gulf Coast facility? Some have expressed concerns about the possibility of somewhat severe galvanic corrosion occurring.





RE: Stainless Steel Pipe on Galvanized Steel Supports
As for galvanic corrosion, the couple between the stainless and galvanized steel favors corrosion on the galvanized material.
Trace elements in the galvanized coating, aluminum, lead, tin, bismuth, cadium, nickel, magnesium and copper could effect the degradation of the stainless. Prime western zinc used in hot dipped galvanizing is 98% zinc, 2% alloying.

I always liked solid HDPE blocks for pipe supports.

Corrosion never sleeps, but it can be managed.
