(OP)
Can mechanical joints be used for above ground piping for 8" ductile iron?  Is there any alternative to welding flanges?

RE: Mechanical Joint

Yes. Flange adapters can be used in lieu of threaded or welded flanges on plain end ductile and steel pipe. The restraints shall be manufactured of ductile iron conforming to ASTM A536. The restraint shall be the Series 1000 E-Z Flange, as manufactured by EBAA Iron, Inc., or approved equal.

RE: Mechanical Joint

(OP)
Do it require special bracing?

RE: Mechanical Joint

Only if the results of the stress analysis on the pipe supports calls for it. At the pressures and flows that are typical in water systems, the answer would be no special bracking.
