(Specification)Standard Specification for Seamless Copper Alloy (UNS No. C69100) Pipe and Tube
Standard Specification for Seamless Copper Alloy (UNS No. C69100) Pipe and Tube
ABSTRACT
This specification establishes the requirements for standard sized seamless pipes, both regular and extra strong, and seamless tubes in straight lengths produced from copper alloy UNS No. C69100 for general engineering purposes. The materials for manufacture shall be cast or extruded shells of such purity and soundness as to be suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure in the finished product. Products shall be produced in tempers TB00 (soft-annealed), TF00 (precipitation-hardened), and HR50 (drawn stress relieved). Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (mass, wall thickness, inside and outside diameters, cross-sectional area, nominal weight, length, squareness of cut, and density), mechanical (tensile and yield strengths, Rockwell hardness, and elongation), physical (electrical resistivity and coefficient of thermal expansion), and chemical composition requirements. Products shall also undergo nondestructive eddy-current and hydrostatic tests.
SCOPE
1.1 This specification establishes the requirements for copper alloy UNS No. C69100 seamless pipe in standard pipe sizes, both regular and extra strong, and seamless tube in straight lengths for general engineering purposes.
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 The following safety hazard caveat pertains only to the test method portion, Section described in this specification: 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

10. Other Requirements
10.1 Nondestructive Testing:
10.1.1 Pipe or tube must be tested in the final heat-treated condition as supplied to the purchaser unless otherwise agreed upon
between the manufacturer and purchaser. Unless otherwise specified, the manufacturer shall have the option of testing the pipe or
tube by one of the following tests:

can select a maximum unbalance signal, such a signal of 0.3% may be used.
10.1.1.3 Pipes or tubes that do not activate the signaling device of the eddy-current tester shall be considered as conforming to
the requirements of this test. Lengths with discontinuities indicated by the tester may, at the option of the manufacturer, be
reexamined or retested to determine whether the discontinuity is cause for rejection. Signals that are found to have been caused

the prescribed limits and the pipe or tube is suitable for its intended application.
10.1.2 Hydrostatic Test—Each length shall stand, without showing evidence of leakage, an internal hydrostatic pressure
sufficient to subject the material to a fiber stress of 7000 psi (48 MPa) determined by the following equation for thin hollow
cylinders under internal pressure. The pipe or tube need not be tested at a hydrostatic pressure of over 1000 psi (6.9 MPa) unless
so specified.

where:
P = hydrostatic pressure, psi (or MPa);
t = thickness of pipe or tube wall, in. (or mm);
D = nominal outside diameter of the pipe or tube, in. (or mm); and
S = allowable stress of the material, psi (or MPa).
11. Dimensions, Mass, and Permissible Variations
11.1 General:
11.1.1 The standard method of specifying wall thicknesses shall be in decimal fractions of an inch.
11.1.2 For the purpose of determining conformance with the dimensional requirements prescribed in this specification, any
measure value outside the specified limiting values for any dimension may be cause for rejection.
11.1.3 Tolerances on any given tube shall be specified with respect to any two, but not all three, of the following: outside
diameter, inside diameter, and wall thickness.
11.2 Dimensions—Nominal dimensions and nominal weights of standard pipe sizes shall be in accordance with Table 3.
11.3 Wall Thickness Tolerances—Wall thickness tolerances shall be in accordance with Table 4. Wall thickness tolerances for
tube shall be in accordance with Table 5.
11.4 Diameter Tolerances—Diameter tolerances for pipe shall be as follows:
11.4.1 Nominal Pipe Size 1 ⁄2 in. (38 mm) and Under—+0.016, −0.031 in. (+0.40, −0.79 mm).
11.4.2 Nominal Pipe Size Over 1 ⁄2 in. (38 mm)—61% of specified diameter.
11.4.3 The dimensional limits of standard pipe sizes are shown in Table 4.
11.4.4 Diameter tolerances of tube shall be in accordance with Table 6.
