Grain Size
Hardness test—When annealed ends are specified for tubing in the stress-relieved condition (see Table 3), the hardness of the ends after annealing shall not exceed the values specified in Table 3.
Flare test—A flare test shall be made on one end of 1 % of the number offinished tube lengths from each lot.
The flare test shall consist of flaring a test specimen with an expanding tool having an included angle of 60° until the specified outside diameter has been increased by 30 %. The flared specimen shall not exhibit cracking through the wall.
Hydrostatic or Nondestructive Electric Test—Each tube shall be subjected to either the hydrostatic test or the nonde-structive electric test. The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.
Hydrostatic Test:
Each tube with an outside diameter 1 ⁄ 8in. (3.2 mm) and larger and tubes with wall thickness of0.015 in. (0.38 mm) and over shall be tested by the manufacturer to an internal hydrostatic pressure of 1000 psi (6.9 MPa) provided that the fiber stress calculated in accordance with the following equation does not exceed the allowable fiber stress, S, indicated below. The tube shall show no evidence of leakage.
P = hydrostatic test pressure, psi (MPa),
S = allowable fiber stress for material in the condition furnished, as follows:
| psi | MPa | |
| Annealed nickel-iron-chromium alloy UNS N08800 | 18 700 | 128.9 |
| Cold-worked nickel-iron-chromium alloy UNS N08800 | 20 700 | 142.7 |
t = minimum wall thickness, in. (mm); equal to the specified average wall minus the permissible “minus” wall tolerance, Table 4 and Table X2.2, or the specified minimum wall thickness, and
D = outside diameter of the tube, in. (mm).
When stress-relieved tubes with annealed ends are to be tested hydrostatically, such pressure testing shall be done prior to annealing of the ends of the tube.
Dimensions and Permissible Variations
Outside Diameter and Wall Thickness—The permissible variations in the outside diameter and wall thickness of tube shall not exceed those prescribed in Table 4 as applicable. (See also Table 5 and Table 6.)
TABLE 4 Permissible Variations in Outside Diameter and Wall Thickness of Condenser and Heat Exchanger Tubes
N OTE 1—The tolerances in the table apply to individual measurements of outside diameter and include out-of-roundness (ovality), and apply to all materials and all conditions, except that for thin wall tubes having a nominal wall of 3 % or less of the outside diameter, the mean outside diameter shall comply with the permissible variations of the above table and individual measurements (including ovality) shall conform to the plus and minus values of the table with the values increased by 1 ⁄ 2 % of the nominal outside diameter.N OTE 2—Eccentricity—The variation in wall thickness in any one cross section of any one tube shall not exceed plus or minus 10 % of the actual (measured) average wall of that section. The actual average wall is defined as the average of the thickest and thinnest wall of that section.
