26 inch pipe (DN 650): outside diameter, wall thickness and weight by schedule
A 26 inch pipe (DN 650) has a 660 mm (26.000 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.
| Schedule | Wall | ID | Weight |
|---|---|---|---|
| Sch 10 | 7.92 mm (0.312 in) | 644.16 mm (25.376 in) | 127.36 kg/m (85.68 lb/ft) |
| STD | 9.53 mm (0.375 in) | 640.94 mm (25.250 in) | 152.88 kg/m (102.72 lb/ft) |
| Sch 20 / XS | 12.70 mm (0.500 in) | 634.60 mm (25.000 in) | 202.74 kg/m (136.30 lb/ft) |
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.
