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..

  1. These wall thicknesses do not permit threading in accordance with ASME B1.20.1.
  2. 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.
