Overview

ASTM B165-19 is the standard specification issued by ASTM International for Nickel-Copper Alloy Seamless Pipe and Tube. This standard covers requirements for seamless pipes and tubes manufactured from nickel-copper alloy UNS N04400, commonly known for its excellent resistance to corrosion and high mechanical strength. The specification details chemical composition, permissible tolerances, mechanical properties, testing, and certification requirements, ensuring that products comply with rigorous industrial and quality standards.

This standard is widely referenced in industries where robust, high-performance piping is essential, particularly in environments exposed to corrosive liquids or gases.

Key Topics

• Material Scope: Covers both cold-worked and hot-worked seamless pipes and tubes in nickel-copper alloy UNS N04400.
• Chemical Composition: The alloy must meet strict composition limits for elements including nickel, copper, iron, manganese, carbon, silicon, and sulfur.
• Mechanical Properties: Specifies minimum tensile strength, yield strength, and elongation for annealed and stress-relieved products.
• Dimensional Tolerances: Details permissible variations in outside diameter, wall thickness, and length, supporting high precision manufacturing standards.
• Testing Requirements: Mandates tension tests, hydrostatic tests, and nondestructive electric tests to verify material quality and integrity.
• Workmanship and Finish: Calls for uniform material free from defects, custom finish conditions, and specific criteria for appearance and straightness.
• Certification and Marking: Requires manufacturers to certify conformance and ensures traceability through detailed product marking.

Applications

ASTM B165-19 nickel-copper alloy seamless pipes and tubes are utilized across a variety of demanding applications, including:

• Marine Engineering: Resistance to seawater corrosion makes these pipes ideal for saltwater piping, offshore platforms, and shipbuilding.
• Chemical Processing: Suitable for handling aggressive chemicals and acids due to their corrosion resistance, used in reactors, heat exchangers, and processing lines.
• Oil & Gas Industry: Used in environments with corrosive fluids, including oil refineries, petrochemical plants, and gas processing facilities.
• Power Generation: Steam piping and condensers benefit from the alloy’s high strength and resistance to stress corrosion cracking.
• Desalination Plants: Preferred for brine handling due to excellent performance against saline environments.
• Pulp and Paper Industry: Suitable for processes involving acidic or caustic media.
• General Industrial Use: Ideal for any system requiring secure, long-lasting, and corrosion-resistant tubing or piping.

Related Standards

For comprehensive compliance, ASTM B165-19 should be considered alongside other relevant ASTM and industry standards:

• ASTM B829: General requirements for nickel and nickel alloys seamless pipe and tube.
• ASTM E8/E8M: Test methods for tension testing of metallic materials.
• ASTM E29: Practices for using significant digits in test data.
• ASME SB-165: The ASME equivalent for boiler and pressure vessel code applications.
• Federal and Military Standards: Includes additional packaging, marking, and quality assurance requirements when specified by the purchaser.

By adhering to ASTM B165-19, manufacturers and end users ensure the reliability, safety, and performance of nickel-copper alloy piping and tubing in critical applications, supporting both compliance and long-term operational resilience.

3 % or less of the specified outside diameter (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.
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.

Ovality—The permissible variations in this table apply to individual measurements, including out-of-roundness (ovality) except for the following:
For pipe and tube having a nominal wall thickness of 3 % or less of the nominal outside diameter, the mean outside diameter shall conform to the permissible variations
of this table and individual measurements (including ovality) shall conform to the plus and minus values of the table, with the values increased by 0.5 % of the nominal
outside diameter.
For pipe and tube over 4 ⁄2 in. (114 mm) in outside diameter with a nominal wall thickness greater than 3 % of the nominal outside diameter, the mean outside diameter
shall conform to the permissible variations of this table and individual measurements shall not exceed twice the permissible variations of the table.

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. in.
(12.7 mm).
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:
Annealed:

and under (120 MPa)
Over 5 in. (127 mm) outside diameter 16 700 psi

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.
