NPS / Nominal Bore

Dimensions are based on ASME B36.10M-2018. Choose a display and material density to calculate theoretical pipe mass from the same independent dimensional data.

Wall thickness values are shown in millimetres. Select “Theoretical weight” to calculate kg/m using the selected density. Values are calculated as π × t × (OD − t) × density; results are theoretical and do not include tolerances, coatings, or manufacturing variation.
