| AOvality-For tube 5 in.(127mm) and under in outside diameter, the
tolerance on the outside diameter applies for individual
measurements and includes ovality. For tube over 5 in.(127mm) in
outside diameter, the mean outside diameter shall conform to the
permissible variations of this table and individual measurements
shall not exceed twice the permissible variations of this table.
BEccentricity-The permissible variations in tihs tale apply to
individual measurements including eccentricity. APPENDIXES (Nonmandatory Information) 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-Wroked, 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 avable in sizes 1/2 to 4 in. (12.7 to 102mm), 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 6 5/8 in. (12.7 to 168 mm) inclusive, in outside diameter in both normal and heavy-wall tube, and pipe sizes, all schedules, of corresponding outside diameter dimensions. X2.3 Hot-Worked Tube X2.3.1 Hot-Worked-Annealed, (Not Pickled) Tube - Has an oxide surface resulitng from the hotworking operation. Intended 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 the outside and inside diameters by picking. Surface may be spot ground for removal of minor surface imperfections at the manufacturer's opion. X2.3.3 Hot-Worked-Annealed (Machined Outside and Inside Diameters) Tubes - The outside and inside diameter surfaces are machined to specified dimensions. Minor surface imperfections may be spot ground for removal, at the manufacturer's option. |
