Nominal Diameter
Nominal Diameter is also known as the mean or average outside diameter and is represented by DN. It is neither equal to the inner diameter (ID) nor the outer diameter (OD) of the pipe. Nominal is a word that denotes non-specificity and in this case, identifies the approximate inner diameter with a...
