4.1.12 Small-Diameter and Light-Wall Tube (Converter Sizes)—See Appendix X1.

5. Chemical Composition
5.1 The material shall conform to the composition limits specified in Table 2.
5.2 If a product (check) analysis is performed by the purchaser, the material shall conform to the product (check) analysis variations in Specification B 829.

6. Mechanical and Other Properties
6.1 Tension Test—The material shall conform to the tensile properties specified in Table 1. The sampling and specimen preparation are as covered in Specification B 829.
6.1.1 Tensile properties for material specified as smalldiameter and light-wall tube (converter sizes) shall be as prescribed in Table X1.1.
6.2 Hydrostatic Test or Nondestructive Electric Test—Each pipe or tube shall be subjected to the Nondestructive Electric Test or the Hydrostatic Test. Unless specified by the purchaser, either test may be used at the option of the producer.

7. Dimensions and Permissible Variations
7.1 Permissible variations for material specified as smalldiameter and light-wall tube (converter size) shall conform to the permissible variations prescribed in Table X1.2.

8. Number of Tests
8.1 Chemical Analysis—One test per lot.
8.2 Tension—One test per lot.
8.3 Hydrostatic or Nondestructive Electric Test—Each piece in each lot.

9. Test Methods
9.1 Hydrostatic Test—Each pipe or tube with an outside diameter 1⁄8 in. (3 mm) and larger and with wall thickness of 0.015 in. (0.38 mm) and over shall be tested in accordance with Specification B 829. The allowable fiber stress, for material in the condition furnished, is as follows:
UNS N02200 UNS N02201
Annealed:
5 in. (127 mm) outside
diameter and under
10 000 psi (70 MPa) 8000 psi (55 MPa)
Over 5 in. outside diameter
8000 psi (55 MPa) 6700 psi (45 MPa)
Stress-Relieved:
All sizes 16 200 psi (110 MPa) 15 000 psi (105 MPa)
9.1.1 When so agreed upon by the manufacturer and purchaser, pipe or tube may be tested to 11⁄2 times the allowable fiber stress given above.
9.1.2 If any pipe or tube shows leaks during hydrostatic testing, it shall be rejected.
9.2 Nondestructive Electric Test—Each pipe or tube shall be examined with a nondestructive electric test as prescribed in Specification B 829.

A Not applicable to outside diameters under 1⁄8 in. (3.2 mm) and wall thicknesses under 0.015 in. (0.38 mm).
B This condition is sometimes designated as “No. 1 Temper.”
C This condition is sometimes designated as “No. 2 Temper.”
D This condition is sometimes designated as “No. 3 Temper.”



A Ovality, Normal Wall Tube—As-Drawn (No. 2 and 3) Tempers—Ovality will be held within the outside diameter tolerances shown in the table. Annealed (No. 1) Temper—Ovality will be held within 2 % of the theoretical average outside diameter.
B Ovality, Light-Wall Tube—As-Drawn (No. 2 and 3)Tempers —Up to but not including 11⁄4 in. (31.8 mm) in outside diameter, ovality will be held within 2 % of the theoretical average outside diameter.
Annealed (No. 1) Temper—Ovality will be held within 3 % of the theoretical average outside diameter. C Wall Tolerances, Light-Wall Tube—The plus and minus wall tolerance shown in the table shall apply down to and including 0.005 in. (0.13 mm) in wall thickness. For wall thicknesses less than 0.005 in. (0.13 mm), the tolerance shall be 60.0005 in. (0.013 mm).
D Random Lengths:
Where nominal random lengths on tubing 1⁄8 in. (3.2 mm) and larger in outside diameter are specified, a length tolerance of 631⁄2 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. (3.2 mm) in outside diameter, and fragile light-wall tubes over this outside diameter are subject to the length range of 1 to 15 ft (0.30 to 4.57 m).
E Straightness—Round tubing is subject to a straightness tolerance of one part in 600 [equivalent to a depth of arc of 0.030 in. (0.76 mm) in any 3 ft (0.91 m) of length].
F 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.
