3.5 inch OD pipe is schedule forty 3 inch iron pipe. You will not
find it at home depot. You will have to go to a plumbing supply and
one that deals with utility pipe.

That's true, but it's also true of pipe schedule from 5S through XXS. Pipe
outside diameter doesn't change, wall thickness (and inside diameter) does.
For a sturdier mount, one could go to a higher schedule, assuming cost was
not an issue.
