ASME SB171 C71500 Copper Nickel "70/30" Tubesheet
ASME SB171 C71500 Copper Nickel "70/30" Tubesheet refers to a
specific type of tubesheet made from a copper-nickel alloy known as
C71500. This alloy is composed of 70% copper and 30% nickel, hence
the "70/30" designation.
Copper-nickel alloys are known for their excellent corrosion
resistance, high strength, and good thermal conductivity. They are
commonly used in various industries, including marine, oil and gas,
chemical processing, and power generation.
The ASME SB171 specification sets the standards for the manufacture
of tubesheets made from copper-nickel alloys. It provides
guidelines for the chemical composition, mechanical properties,
dimensions, tolerances, and testing requirements of the tubesheet.
Tubesheets are used in heat exchangers, condensers, and other types
of pressure vessels to support and hold the tubes in place. They
provide a seal between the tubes and the shell, ensuring efficient
heat transfer and preventing leakage.
Overall, ASME SB171 C71500 Copper Nickel "70/30" Tubesheets are a
reliable and widely used choice in various industrial applications
where corrosion resistance and high strength are required.
