Note: Rockwell or equivalent hardness values apply only to the annealed ends of stress-relieved tubing. Caution should be observed in using the Rockwell test on thin material,as the results may be affected by the thickness of specimen. For thickness under 0.050 in. (1.27 mm) the use of the Rockwell superficial or the Vickers hardness test is suggested. For hardness conversions for nickel and high-nickel alloys see Hardness Conversion Tables E140.
 
In the case of stress-relieved tubes furnished with annealed ends, the tension test shall be made on the stressrelieved tubes prior to annealing the ends.
 

Testings
Chemical Analysis
Mechanical Properties
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.

 

where:
P = hydrostatic test pressure, psi (MPa),
S = allowable fiber stress for material in the condition furnished, as follows:

	psi	MPa
Annealed nickel-iron-chromium-molybdenum copper alloy UNS N08825	21 000	144.8

 
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.

Applications

The mechanical and physical properties of C71500 copper pipe are exceptionally good, with good ductility, high hardness, beautiful color and corrosion resistance. And easy to shape, process and weld. It is widely used in shipbuilding, petrochemical, construction, electric power, electrical appliances, precision instruments, medical equipment, daily necessities, handicrafts, musical instrument production and other fields
 

Features

C71500 cupronickel is a copper-based alloy with nickel as the main additive element. It is silvery white with metallic luster, so it is called cupronickel. After the material is processed into a tubular shape, it becomes a cupronickel tube.
C71500 copper pipe is pure copper plus nickel. Can significantly improve the strength, corrosion resistance, hardness, electrical resistance and thermoelectricity, and reduce the temperature coefficient of resistivity. Therefore, compared with other copper alloys, C71500 copper tube has exceptionally good mechanical and physical properties, good ductility, high hardness, beautiful color, corrosion resistance, and good deep drawing performance.
