- Weights are approximate net weights per piece, for reference only (calculated from OD and wall thickness per ASME B16.9).
- Schedules marked 'S' are stainless steel weights; others are carbon steel weights.
- Volumes are external contour (packaging) volume per piece in m3, kept as written in the source (e.g. '0.038*10-3' = 0.038 x 10^-3 m3).
- The approximate weight of ≥DN1300 (NPS52) calculated based on a nominal wall thickness of 10mm is listed under the STD column.
