What happen after steam blowing process finished?

[Eduardo1982]

Hey guys. I hope everybody are fine.
Are there any recommended practise or standard code that establish how long can wait my boiler and pipes from finished steam or air blowing to start-up without preservation?

I think that for some reason after steam and air blowing after purgint it if you cannot start up with your boiler the best is to pressurize it with nitrogen under a positive pressure.
