Galvanized "strap" around steel gas pipe

Will electrolysis occur between these metals.

[Rick Cantrell]

Any time dissimilar metals are in contact they may have a galvanic reaction, however I think it unlikely for this to be a problem here.

I don't remember my chemistry, but I would say probably not. The underlying metal of the strap is steel. Zinc is used to coat steel pipe.

Wasn't galvanized plumbers tape designed to hold up steel pipes?

[Jerry Peck]

Looks like steel pipe with steel straps, in which case, no, no galvanic corrosion.
