Based on the aforementioned consideration, we can simply calculate the inner diameter of a pipe by subtracting the pipe wall thickness twice from the number that corresponds to the outer diameter. This consideration is important pipe schedule chart engineers since the inner diameter is what determines the flow velocity and rate.
Due to corrosion resistance properties of stainless steel, advancement of high alloy stainless steel and fusion welding less thickness pipe can be work satisfactorily without fear of early failure. This is simply a difference in terminology, where one group refers to "Extra Extra Heavy" and another pipe schedule chart to "Extra Extra Strong".

The physical dimensions of each are the same, and the terms may be used interchangeably. This critical dimension is referred to as the nominal bore NB. pipe schedule chart
Definition of Schedule Number: If the inner pipe dimension is to be measured then the weld bead should be subtracted, if welding is applicable. The ISO sizes provide a metric name for existing inch sizes, resulting in a pipe schedule chart
