32 inch pipe (DN 800): outside diameter, wall thickness and weight by schedule
A 32 inch pipe (DN 800) has a 813 mm (32.000 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) | 797.16 mm (31.376 in) | 157.25 kg/m (105.69 lb/ft) |
| STD | 9.53 mm (0.375 in) | 793.94 mm (31.250 in) | 188.83 kg/m (126.78 lb/ft) |
| Sch 20 / XS | 12.70 mm (0.500 in) | 787.60 mm (31.000 in) | 250.65 kg/m (168.37 lb/ft) |
| Sch 30 | 15.88 mm (0.625 in) | 781.24 mm (30.750 in) | 312.17 kg/m (209.62 lb/ft) |
| Sch 40 | 17.48 mm (0.688 in) | 778.04 mm (30.624 in) | 342.94 kg/m (230.29 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.
