Wall thicknesses follow ASME B36.10M; Sch 5 and Sch 10 for 4″–12″ are the stainless 5S/10S walls from ASME B36.19M. Weights are calculated for carbon steel, plain end: 10.69 × (OD − wall) × wall. A dash means the schedule isn't standard for that size. For reference only — confirm against the mill test report.
