 Applications: Tube, Pipe & Fittings: Commercial Tube: Copper and Copper Alloy – Tube and Pipe
Tubes may be annealed at any intermediate stage when drawing to smaller sizes is required because of the metal’s work hardening.
ACR tube is available in annealed (soft) coils or drawn (hard) straight lengths and is intended for use in the field with special fittings for connections, repairs, and alterations in air conditioning and refrigeration installations.
Mechanical joints involving flared tube ends are frequently used for underground tubing, for joints where the use of heat is impractical and for joints that may have to be disconnected from time to time.

 Heat Resistant Stainless Steels And Nickel Alloys
Alloy 800 is not immune but is less susceptible to sigma formation than the 300 series of stainless steel.
High nickel alloys are rarely used in refinery or petrochemical plants in hydrogen-hydrogen sulphide environments because of their susceptibility to the formation of deleterious nickel sulphide.
Alloy 600, with 72% nickel, is often used in the heat treating industry and occasionally in refining and petrochemical applications involving ammonia at temperatures above 650F (343C).

 Effects of Composition, Processing, and Structure on Properties of Copper and Copper Alloys
High-copper alloys (C16000 to C19900) are designed to maintain high conductivity while using dispersions and precipitates to increase strength and softening resistance: iron dispersions in Cu-(1.0-2.5)Fe alloys (C19200, C19400), chromium precipitates in Cu-1Cr (C18200), and the coherent precipitates in the Cu-(0.3-2.0)Be-Co-Ni age-hardening alloys (C17200, C17410, and C17500).
Copper-nickel-zinc alloys, also called nickel-silvers, are a family of solid-solution-strengthening and work-hardening alloys with various nickel-zinc levels in the Cu-(4-26)Ni-(3-30)Zn ternary alloy system valued for their strength, formability, and corrosion and tarnish resistance, and, for some applications, metallic white color.
Work hardening is the principal hardening mechanism applied to most copper alloys, the degree of which depends on the type and amount of alloying element and whether the alloying element remains in solid solution or forms a dispersoid or precipitate phase.

 TUBE ALLOYS - Definition, explanation
TUBE ALLOYS was a cryptonym for nuclear weapons used during World War II, when the very possibility of nuclear weapons was kept at such a high level of secrecy that it had to be referred to by a cryptonym even in the highest circles of government.
The term was most famously used in the section of the Quebec Agreement between Franklin D. Roosevelt and Winston Churchill of August 19, 1943, formally entitled "Articles of Agreement governing collaboration between the authorities of the U.S.A. and U.K. in the matter of Tube Alloys".
Later in the war, tube alloy came to refer specifically to the synthetic element plutonium, whose very existence was secret until its use in the atomic bombing of Nagasaki.

TUBE ALLOYS - TUBE ALLOYS was the code-name for the British nuclear weapon programme during World War II, when the very possibility of nuclear weapons was kept at such a high level of secrecy that it had to be referred to by code even in the highest circles of government.

 MCP Low Melting Point Alloys for Tube Bending, Section Bending
The recommended MCP low melting-point alloys have mechanical properties that are unusually well suited to the task of support during bending.
It is also possible to preserve a uniform annular gap while avoiding wrinkling in bending concentric tubes, for which purpose the alloy replaces sand, shot or ice as the filler.
The low melting-points ensure that the profile, tube or section is neither damaged nor distorted during filling and melt-out.

 Foster Wheeler: Publications
In Phase I of this project, laboratory experiments were performed on a variety of developmental and commercial tubing alloys and claddings by exposing them to fireside corrosion tests which simulated a superheater or reheater in a coalfired boiler.
The alloy samples were duplicated in such a manner as to expose each alloy to a temperature in each of the temperature bands [621 to 677EC (1150 to 1250EF) and 677 to 727EC (1250 to 1340EF)].
The peak temperature for wastage is somewhat different for each alloy, since the temperature range in which the molten salt is stable depends on the interaction of the molten salt with the surface of the alloy.

 Key Issues: Nuclear Weapons: History: Pre Cold War: Manhattan Project: Tube Alloys Deal
The suggestion that the world should be informed regarding tube alloys, with a view to an international agreement regarding its control and use, is not accepted.
The matter should continue to be regarded as of the utmost secrecy; but when a "bomb" is finally available, it might perhaps, after mature consideration, be used against the Japanese, who should be warned that this bombardment will be repeated until they surrender.
Full collaboration between the United States and the British Government in developing tube alloys for military and commercial purposes should continue after the defeat of Japan unless and until terminated by joint agreement.

 corrosioneering - pyrolysis furnaces
Alloy performance for ethylene furnace tubing depends on good creep strength, carburization resistance, a stable protective oxide layer, high-temperature ductility, proper operation and maintenance.
However, areas requiring attention are: improving design and assembly, avoiding points of stress build-up, initiating careful startup and shutdown procedures, increasing run lengths between de-coking, and maintaining good furnace operation and prudent maintenance procedures.
Stronger alloys allow operating at higher temperatures with higher productivity or designing at the same temperature with a thinner tube wall and deriving better thermal cycling fatigue and carburization resistance.
