I always use the Corrosion Resistance Ratio (CRR) argument. Basically, the thickness of schedule 10 piping is greater than or equal to the thickness of the first exposed thread of threaded schedule 40. Using this argument, schedule 10 should theoretically last at least as long as threaded schedule 40. You can't use this argument if they call for grooved schedule 40.
