Tolerances & Variations For Cold & Hot Finished Round Tubing

Hot-Finished Round Tubing Permissible Variations:

These tolerances apply to cut lengths up to an including 24 Ft. (7.3M). For lengths over 24Ft. an additional over tolerance of 1/8in (3.1mm) for each 10ft. (3m) or fraction thereof shall be permissible up to a maximum tolerance of 1/2 in. (12.7mm)

Cold-Finished Round Tubing Permissible Variations:

  1. Tolerances of tubes produced by the rod or bar mandrel process and which have an inside diameter under 1/2 in (12.7mm) (or an inside diameter under 5/8 in. When the wall thickness is more then 20% of the outside diameter.) Are as shown in this table except that wall thickness tolerances are 10% over and under the specified wall thickness.
  2. For Ovality values, the tolerance for average outside diameter at any one cross section does not exceed the outside diameter tolerance value for the applicable outside diameter.
  3. Many tubes with wall thicknesses more then 25% of outside diameter or with wall thicknesses over 1 1/4 in. Or weighing more then 90lb/ft. are difficult to draw over a mandrel. Therefore the wall thickness can vary 12 1/2% over and under that specified.
  4. For those tubes with inside diameter under 1/2 in (or under 5/8 in when the wall thickness is more then 20% of the outside diameter) which are not commonly drawn over a mandrel, A is not applicable. Therefore the wall thickness can vary 15% over and under that specified, and the inside diameter is governed by both the outside diameter and wall thickness tolerances.
  5. These tolerances apply to cut lengths up to an including 24 ft. For lengths over 24ft, an additional over tolerance of 1/8 in. for each 10ft. or fraction thereof shall be permissible, up to a maximum tolerance of 1/2 in.
