## Size and weight chart (seamless pipe)

- Theoretical weight per metre = (OD - wall) x wall x 0.02466 kg/m.
- The schedule reference covers NPS 1/4 to NPS 24 (OD 13.7-610 mm), with STD, SCH40,
  SCH80 and SCH160 nominal walls from 2.24 mm to 33.32 mm. The separate Chinese
  standard table covers selected 89 / 102 / 114 mm diameters with walls from 8 mm to 25 mm.
- Examples: 33.4 x 3.38 mm = 2.5 kg/m; 88.9 x 7.62 mm = 15.27 kg/m;
  168.3 x 7.11 mm = 28.26 kg/m; 219.1 x 12.7 mm = 64.64 kg/m.
- A 20 ft container takes about 25 tonnes; loading plan issued before booking.
