GENERAL NOTES..
- Tolerances.. Variations in dimensions differ depending upon the method of manufacture employed in making the pipe to the various pecifications available. Permissible variations for dimensions are indicated in each specification.
- 1 lb/ft = 1.4895 kg/m.
- Weights (masses) are given in pounds per linear foot (kilograms per meter) and are for carbon steel pipe with plain ends.
- The different grades of stainless steel permit considerable variations in weight (mass). The ferritic stainless steels may be about 5% less, and the austenitic stainless steels about 2% greater, than the values shown in this Table, which are based on weights (masses) for carbon steel.
NOTES..
- These wall thicknesses do not permit threading in accordance with ASME B1.20.1.
- These dimensions do not conform to ASME B36.10M.

Pipes weight tolerance
The pipes weight tolerance depends on the nominal pipe size.
- Pipes NPS 12 (DN300, 323.8mm) and under, weight tolerance is.. -3.5% / +10%
- Pipes over NPS 12 (DN300, 323.8mm),weight tolerance is.. -5% / +10%
- Pipe of NPS 4 (DN100, 114.3mm) and smaller may be weighed in convenient lots; pipe in sizes larger than NPS 4 shall be weighed separately
Pipes length tolerance
- Seamless and Welded (no filler metal added).
If definite cut lengths are ordered, no length of pipe shall be under the length specified and not more than 1/4 in. (6.35 mm) over that specified. - Forged and Bored, Cast, and Cast Cold-Wrought.
If definite cut lengths are ordered, no length of pipe shall be under the length specified and not more than 1/8 in. (3.2 mm) over that specified. - For pipe ordered to random lengths, the lengths and variations shall be agreed upon between the manufacturer and purchaser.
