There are two reasons for a "Spec Break" in piping.
The first reason for a Spec Break is a change in Pressure and therefore flange rating (higher rating down to a lower rating)
The second reason for a Spec Break is a change in Material (example: Stainless Steel to Carbon Steel)
Therefore you DO need a "Spec Break" even though there is no change in the basic flange class rating.
