10 inch pipe (DN 250): outside diameter, wall thickness and weight by schedule
A 10 inch pipe (DN 250) has a 273.0 mm (10.750 in) outside diameter in every schedule: what changes is the wall, and with it the inside diameter and the weight. Designations that give the same wall share a row.

Plain-end weight of carbon steel pipe, by the standard's own formula: 10.69 × (D − t) × t in lb/ft, with D and t in inches (0.0246615 × (D − t) × t in kg/m, in mm). Austenitic stainless weighs about 2% more.
