(3.2 mm) and larger in outside diameter are specified, a length tolerance of 6 31⁄2 ft (1.06 m) applies to the nominal length. This is a total spread of 7 ft (2.10 m). Random lengths in sizes 1⁄8 in. (3.2 mm) and larger in outside diameter shall be subject to a length range of 5 to 24 ft (1.50 to 7.30 m). Long random lengths are subject to a range of 15 to 22 ft (4.57 to 6.70 m). Random lengths in sizes up to, but not including, 1⁄8 in.

G When specified, the tolerance spreads of this table may be applied as desired. However, when not specified, the tolerances in this table will apply. It should be noted that inside diameter tolerances are based upon the outside diameter range. B 423 – 05 (2009) 3 X2. CONDITIONS AND FINISHES NORMALLY SUPPLIED X2.1 Scope X2.1.1 This appendix lists the conditions and finishes in which pipe and tube (other than converter sizes) are normally supplied. These are subject to change, and the manufacturer should be consulted for the latest information available. X2.2 Cold-Worked Tube and Pipe X2.2.1 Cold-Worked, Annealed, with Ground Outside Diameter—The inside diameter may have a bright finish when material is annealed in a protective atmosphere; otherwise, the inside diameter is supplied descaled as necessary. It is available in sizes 1⁄2 to 4 in. (12.7 to 102 mm), inclusive, in outside diameter in both normal and heavy-wall tube, and pipe sizes, all schedules, of corresponding outside-diameter dimensions. X2.2.2 Cold-Worked, Annealed, and Pickled (Not Ground)—Outside and inside diameter will have dull, matte (pickled) surfaces. It is available in sizes 1⁄2 to 65⁄8 in. (12.7 to 168 mm), inclusive, in outside diameter in both normal and heavy-wall tube, and pipe sizes, all schedules, of correspond- ing outside-diameter dimensions. X2.3 Hot-Worked Tube X2.3.1 Hot-Worked-Annealed (Not Pickled) Tube—Has an oxide surface resulting from the hot-working operation. In- tended generally for machined parts where the oxide surface will be removed. X2.3.2 Hot-Worked-Annealed (Pickled) Tube—Has the oxide surface removed on both outside and inside diameters by pickling. Surface may be spot ground for removal of minor surface imperfections at the manufacturer’s option. X2.3.3 Hot-Worked-Annealed (Machined Outside and In- side Diameters) Tubes—The outside and inside diameter surfaces are machined to specified dimensions. Minor surface imperfections may be spot ground for removal, at the manu- facturer’s option.
