I hope it wasn't cement lined ductile if you are cutting it with a chop saw

I'd worked for a firm in the 80's that used DI for large diameter piping
around fire pumps where we field cut spool pieces with a chop saw, added
uni-flanges, and rodded the whole thing together.
Much easier field installation, and coated pipe on the suction side.
Other than short stubs, however, I'd try to avoid running DI inside like the
plague. I've seen it done, LHU was one instance in PA, and it wasn't pretty.
If it's your best option, go do it.

DI is commonly seen hanging under bridges and overpasses for domestic water.

Typically black carbon steel is used for the foam-water systems but
galv. can be used. Most foam mfgr. data will state not to used
galvanized piping only where it would be in direct contact with the
undiluted foam concentrate.
CLDI is typical for UG, have never heard of anyone trying to use it
above ground. Better check it's listing before proceeding down that
road.
As far as life span, might try calling various pipe mfgrs. and see if
they have any data concerning life cycle based on various installation
conditions.
