2007 SECTION II, PART B SB-163
SPECIFICATION FOR SEAMLESS NICKEL AND
NICKEL ALLOY CONDENSER AND HEAT-EXCHANGER
TUBES
SB-163
(Identical with ASTM Specification B 163-04 except that certification has been made mandatory and Appendix X2 and its references in paras.
4.1.2, 4.1.10, and 7.1 have been deleted, and E 76 has been deleted from paras. 2.1 and 12.1.)
1. Scope
1.1 This specification covers seamless tubes of nickel
and nickel alloys, as shown in Table 1, for use in condenser
and heat-exchanger service.
1.2 This specification covers outside diameter and aver-
age wall, or outside diameter and minimum wall tube.
1.2.1 The sizes covered by this specification are 3
in. (76.2 mm) and under in outside diameter with minimum
wall thicknesses of 0.148 in. (3.76 mm) and under, and
with average wall thicknesses of 0.165 in. (4.19 mm) and
under.
1.3 Tube shall be furnished in the alloys and conditions
as shown in Table 2.
1.4 The values stated in inch-pound units are to be
regarded as the standard. The values given in parentheses
are for information only.
1.5 The following safety hazards caveat pertains only
to the test method portion, Section 12, of this specification.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsi-
bility of the user of this standard to become familiar with
all hazards including those identified in the appropriate
Material Safety Data Sheet 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.

NOTE:
(A) Alloy UNS N08800 is normally employed in service temperatures
up to and including 1100°F (593°C). Alloys UNS N08810, UNS
N08811, and UNS N08120 are normally employed in service tem-
peratures above 1100°F (539°C) where resistance to creep and
rupture is required, and it is annealed to develop controlled grain
size for optimum properties in this temperature range.
performance of material ordered under this specification.
Examples of such requirements include, but are not limited
to, the following:
4.1.1 Alloy (Table 1).
4.1.2 Condition (Temper) Table 3 and Appendix X1.
4.1.2.1 If annealed ends for stress relieved tubing
are desired, state length of end to be annealed and whether
or not one end or both ends are to be annealed.
4.1.3 Finish.
167
4.1.4 Dimensions—Outside diameter, minimum or
average wall thickness (in inches, not gage number), and
length.
4.1.5 Fabrication Operations:
4.1.5.1 Cold Bending or Coiling.
4.1.5.2 Packing.
4.1.5.3 Rolling or Expanding into Tube Sheets.
4.1.5.4 Welding or Brazing—Process to be
employed.
4.1.5.5 Hydrostatic Test or Nondestructive Elec-
tric Test—Specify type of test (6.5).
4.1.5.6 Pressure Requirements—If other than
required by 6.5.
4.1.5.7 Ends—Plain ends cut and deburred will
be furnished.
4.1.6 Supplementary Requirements—State nature
and details.
4.1.7 Certification—Certification is required (Sec-
tion 15).
4.1.8 Samples for Product (Check) Analysis—
Whether samples for product (check) analysis shall be
furnished.
4.1.9 Purchaser Inspection—If purchaser wishes to
witness tests or inspection of material at place of manufac-
ture, the purchase order must so state indicating which
tests or inspections are to be witnessed (Section 13).
5. Chemical Composition
5.1 The material shall conform to the composition lim-
its specified in Table 1.
5.2 If a product (check) analysis is performed by the
purchaser, the material shall conform to the product (check)
analysis per Specification B 880.
6. Mechanical Properties and Other Requirements
6.1 Mechanical Properties—The material shall con-
form to the mechanical properties specified in Table 3.
6.2 Hardness—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.
6.3 Flare—A flare test shall be made on one end of
1% of the number of finished tube lengths from each lot.
For less than 100 tubes in a lot, a flare test shall be made
on one end of one tube length in the lot. In the case of
stress relieved tubing with annealed ends, the test shall be
made prior to, or subsequent to, annealing of the ends at
the option of the manufacturer.

NOTE:
(A) 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 E 140.
6.3.1 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.
6.4 Grain Size—A transverse sample representing full-
wall thickness of annealed alloys UNS N08120, UNS
N08810 and UNS N08811 shall conform to an average
grain size of ASTM No. 5 or coarser.
6.5 Hydrostatic or Nondestructive Electric Test —Each
tube shall be subjected to either the hydrostatic test or the
nondestructive electric test. The type of test to be used
shall be at the option of the manufacturer, unless otherwise
specified in the purchase order.
6.5.1 Hydrostatic Test:
6.5.1.1 Each tube with an outside diameter 1⁄8 in.
(3.2 mm) and larger and tubes with wall thickness of 0.015
in. (0.38 mm) and over shall be tested by the manufacturer
168
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 p 2St/D
where:
P p hydrostatic test pressure, psi (MPa),
S p allowable fiber stress for material in the condition
furnished, as follows:
t p minimum wall thickness, in. (mm); equal to the
specified average wall minus the permissible
“minus” wall tolerance, Table 4, or the specified
minimum wall thickness, and
D p outside diameter of the tube, in. (mm).

GENERAL NOTES:
(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.
(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.
NOTE:
(A) Wall variations as indicated above are applicable only to the wall as ordered, for instance, to minimum or to average wall, but not to both.
6.5.1.2 When so agreed upon between the manu-
facturer and the purchaser, tube may be tested to 11⁄2 times
the above allowable fiber stress.
6.5.1.3 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.
