Copper nickel pipe with aluminum fin tube

What are copper nickel pipes?

Copper nickel pipes, also known as cupronickel pipes, are pipes made from an alloy of copper and nickel in varying proportions. The most common alloy is composed of 90% copper and 10% nickel, known as 90/10 copper nickel. Other common alloys include 70/30 copper nickel and 95/5 copper nickel.

Copper nickel pipes are known for their excellent resistance to corrosion, particularly in marine environments, where they are commonly used for seawater piping, heat exchangers, and condensers. They also have good mechanical properties, including high strength and ductility.

The 90/10 copper nickel alloy is particularly resistant to biofouling, making it a popular choice for applications in which marine organisms might attach themselves to surfaces. It is also highly resistant to stress corrosion cracking and has good erosion-corrosion properties.

Copper nickel pipes can be easily fabricated, welded, and brazed, making them a versatile choice for a wide range of applications.

Copper nickel pipe with aluminum fin tube

Copper nickel pipe with aluminum fin tube is a common configuration for heat exchangers in various industrial applications. The copper nickel pipe provides good corrosion resistance, while the aluminum fin tube offers efficient heat transfer.

The fin tube consists of a copper nickel pipe with aluminum fins attached to the outside surface. The fins increase the surface area of the tube, which enhances heat transfer. The aluminum fins are bonded to the copper nickel pipe using a mechanical or metallurgical process, such as extrusion, rolling, or brazing.

This type of heat exchanger is commonly used in the marine industry for seawater cooling systems, where the copper nickel pipe resists corrosion from saltwater, and the aluminum fins provide effective heat transfer. It is also used in HVAC (heating, ventilation, and air conditioning) systems, where it can efficiently transfer heat between air and water.

Overall, copper nickel pipe with aluminum fin tube is a reliable and effective configuration for heat exchangers in various industrial applications.
