Schedule 100 steel pipe: outside diameter, wall thickness and weight chart
Schedule 100 in ASME B36.10M gives one wall for each size, from 8 inch to 24 inch. The outside diameter is that of the size, the same in every schedule; the inside diameter is the outside diameter less two walls.

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.
Questions
- What is schedule 100 pipe?
- It is the schedule 100 wall series in ASME B36.10M: one wall for each size, from 8 inch to 24 inch. The outside diameter is that of the size, and the inside diameter is the outside diameter less two walls.
- How do you calculate the weight of schedule 100 pipe?
- With the standard's own formula: weight in lb/ft = 10.69 × (D − t) × t, with the outside diameter D and the wall t in inches; in kg/m, 0.0246615 × (D − t) × t in millimetres. That is carbon steel; austenitic stainless weighs about 2% more.
