Standard Specification for Nickel-Copper Alloy (UNS N04400) Seamless Pipe and Tube

ABSTRACT
This specification covers nickel-copper alloy UNS N04400 in the form of cold-worked seamless pipe and tube. The material shall conform to the composition limits specified. Tension test, hydrostatic test, nondestructive electric test, and rounding method shall be done in accordance to the specified requirements.
SCOPE
1.1 This specification2 covers nickel-copper alloy UNS N044003 in the form of cold-worked seamless pipe and tube in the conditions shown in Table 1 and Table X1.1.  
1.1.1 Hot worked material is available. Properties and permissible tolerances are to be agreed upon between the manufacturer and purchaser.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.

shall conform to the permissible variations of this table and individual measurements shall not exceed twice the permissible variations of the table.
B
Eccentricity—The permissible variations in this table apply to individual measurements including eccentricity.
7.2 Length—When material is ordered cut-to-length, the length shall conform to the permissible variations prescribed in Table
4.
7.3 Straightness—Material shall be reasonably straight and free of bends and kinks.
7.4 Ends—Ends shall be plain cut and deburred.
7.5 Permissible variations for material specified as small-diameter and light-wall tube (converter size) shall conform to the
permissible variations prescribed in Table X1.2.
8. Workmanship, Finish, and Appearance
8.1 The material shall be uniform in quality and temper, smooth, commercially straight, and free of injurious imperfections.
9. Sampling
9.1 Lot Definition:
9.1.1 A lot for chemical analysis shall consist of one heat.
9.1.2 A lot for all other testing shall consist of all material from the same heat, nominal size (excepting length), and condition.
9.1.2.1 Where material cannot be identified by heat, a lot shall consist of not more than 500 lb (227 kg) of material in the same
condition and nominal size (excepting length).
9.2 Test Material Selection:
9.2.1 Chemical Analysis—Representative samples from each lot shall be taken during pouring or subsequent processing.
9.2.1.1 Product (Check) Analysis shall be wholly the responsibility of the purchaser.
9.2.2 Mechanical and other Properties—Samples of the material to provide test specimens for mechanical and other properties
shall be taken from such locations in each lot as to be representative of that lot. Test specimens shall be taken from material in
the final condition.
10. Number of Tests
10.1 Chemical Analysis—One test per lot.
10.2 Tension—One test per lot.
10.3 Hydrostatic or Nondestructive Electric Test—Each piece in each lot.

These permissible variations in length apply to pipe or tube in straight lengths.
They apply to cut lengths up to and including 24 ft (7.3 m). For lengths over 24 ft,
an additional over-tolerance of ⁄8 in. (3.2 mm) for each 10 ft (3.0 m) or fraction
thereof shall be permissible up to a maximum additional over-tolerance of ⁄2 in.
(12.7 mm).

11. Specimen Preparation
11.1 Room Temperature Tensile Specimen—Material shall be tested in the direction of fabrication. Whenever possible, all pipe
and tube shall be tested in full tubular size. When testing in full tubular size is not possible, longitudinal strip specimens, or the
largest possible round specimen, shall be used. In the event of disagreement when full tubular testing is not possible, a longitudinal
strip specimen with reduced gauge length as contained in Test Methods E8 shall be used.
12. Test Methods
12.1 Chemical Composition—In case of disagreement, the chemical composition shall be determined in accordance with Test
Methods E76.
12.2 Tension Test—Tension testing shall be conducted in accordance with Test Methods E8.
12.3 Hydrostatic or Nondestructive Electric Test—Each pipe or tube with an outside diameter ⁄8 in. (3 mm) and larger and with
wall thickness of 0.015 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:
P 5 2St/D (1)
where:
P = hydrostatic test pressure, psi (or MPa)
S = allowable fiber stress, for material in the condition (temper) furnished as follows:
where:
P = hydrostatic test pressure, psi (or MPa)
S = allowable fiber stress, for material in the condition (temper) furnished as follows:
Annealed:
5 in. (127 mm) outside diameter 17 500 psi
and under (120 MPa)
Over 5 in. (127 mm) outside diameter 16 700 psi
(115 MPa)
Stress-relieved:
All sizes 21 200 psi
(145 MPa)
t = minimum wall thickness, in. (or mm), equal to the specified nominal wall minus the permissible minus wall tolerance, or
the specified minimum wall thickness, and,
D = outside diameter of the pipe or tube, in. (or mm).
12.3.1 When so agreed upon between the manufacturer and purchaser, pipe or tube may be tested to 1 ⁄2 times the allowable
fiber stress given above.
12.3.2 If any pipe or tube shows leaks during hydrostatic testing, it shall be rejected.
12.4 Nondestructive Electric Test—Each pipe or tube shall be examined with a nondestructive electric test in accordance with
Specification B829.
12.5 Rounding Method—For purposes of determining compliance with the specified limits for requirements of the properties
listed in the following table, an observed value, or a calculated value, shall be rounded as indicated below, in accordance with the
rounding method of Practice E29:
Rounded Unit for Observed
Test
or Calculated Value
Chemical composition and nearest unit in the last right-hand place of
tolerances (when expressed in figures of the specified limit. If two choices
decimals) are possible, as when the digits dropped are
exactly a 5 or a 5 followed only by zeros,
choose the one ending in an even digit with
zero defined as an even digit.
Tensile strength, yield strength nearest 1000 psi (6.9 MPa)
Elongation nearest 1 %
13. Inspection
13.1 Inspection of the material shall be agreed upon between the purchaser and the supplier as part of the purchase contract.
14. Rejection and Rehearing
14.1 Material that fails to conform to the requirements of this specification may be rejected. Rejection should be reported to the
producer or supplier promptly and in writing. In case of dissatisfaction with the results of the test, the producer or supplier may
make claim for a rehearing.
