Corrosion on RMC depends on soil type. Around here RMC can last for 50+ years. Corrosive environments are addressed in 344.10 Uses Permitted, (B) Corrosive Environments.
Please explain the use of Noalox for RMC and how its used?

NOALOX is a brand or Penetrox or joint compound ,you would apply to each connection/fitting to inhibit corrosion and inhibit the loss of continuity.

galvanized conduit rust and corrodes fairly quickly,without the use of noalox it happens even quicker.

Not sure that "noalox" is a compound that meets the requirements of 300.6(A). There are some that do, but the typical no-ox ones are for use with aluminum connections and not with conduit connections.

Kopr-shield would be a better product to use. There brochure specifically mentions use on assembly of raceways.
