This document contains a chart listing pipe sizes, outside diameters, wall thicknesses, and weights. The pipe sizes range from 1/8 inch to 72 inches in nominal diameter. For each size, the chart provides the outside diameter in mm and the wall thickness in mm for various standard wall thickness designations including SCH 10, SCH 20, SCH 30, etc. Heavier wall thicknesses are shown for larger pipe sizes.
