Marine Applications of Copper & Nickel

What is Copper-nickel?

Copper-nickel alloys, also known as cupronickel alloys, are frequently employed in maritime applications due to their strong resistance to seawater corrosion, low macrofouling rates, and superior fabricability.

Copper is strengthened and more resistant to corrosion when nickel is added, and the alloy is still malleable. To improve copper strength, nickel’s corrosion resistance, hardness, weldability, and castability, other elements can be added.

The most popular Copper Nickel 95/5 C70400 Pipes are composed of 90% copper and 10% nickel. It is used in power generating, desalination, offshore oil and gas production, as well as naval and commercial shipping.

Where more resistance to saltwater flow, sand abrasion, wear, and galling, as well as stronger mechanical qualities, are required, alloys with a 30% nickel content (C71500, C71640), as well as those that are more strongly alloyed with aluminum, chromium, or tin, are employed.

Marine Applications of Copper and Nickel

Shipbuilding and Repair: Copper-nickel is used for cooling seawater, bilge and ballast, sanitary, fire fighting, inert gas, hydraulic and pneumatic systems, and chiller systems in shipbuilding and ship repair. Additionally, they can be utilized for feed lines to desalination plants and heating coils in cargo tanks. An interactive diagram of a ship’s systems serves as an example of this.

Desalination Plants: Copper Nickel Pipes are well-established alloys in thermal desalination facilities. Copper-nickel is frequently used for heat rejection and recovery sections and brine heaters in Multi-Stage Flash (MSF) desalination. Tubing in the evaporator section is made of copper-nickel for Multiple Effect Distillation (MED).

Offshore Oil and Gas Platforms and Processing: Floating production, storage, and offloading vessels and offshore oil and gas platforms utilize copper-nickel alloy systems (FPSOs). The description of splash zone sheathing in 90-10 Cu-Ni.

Power Generation: Steam turbine condensers, oil coolers, auxiliary cooling systems, and high-pressure pre-heaters in nuclear and fossil fuel power plants can all use copper-nickel pipes and parts. They can transport fresh water, brackish water, and clean seawater. Additionally, copper-nickel has many advantages for maritime renewable energy (e.g., wind farms and wave and tidal devices).

Seawater System Design: Designing a seawater system with a high degree of reliability while minimizing maintenance is a top priority. For pipework made of copper-nickel, methods for achieving good performance are provided. The handling of galvanic problems, pressure systems, and water hammers are also covered.

Seawater System Components: High-quality seawater system designs must include copper-nickel condenser and heat exchanger tubes, tube sheets, pipelines, fittings, pumps, and water boxes. Also mentioned are appropriate materials for copper-nickel system pumps and valves.

Hulls of Boats and Ships: Copper-nickel is an uncommon material for boat hulls because of its excellent resistance to biofouling and corrosion. Examples of sheathing applications as well as solid plate and clad steel plate hull construction are provided.

Antimicrobial: Alloys made of copper and nickel have antibacterial properties. Copper-nickel surfaces are resistant to the growth of bacteria, viruses, and fungi. A link to a website focused on copper’s antibacterial properties is provided.

Applications and Benefits of Cu Ni Pipe

What is Cu Ni alloy?

Copper (Cu) and nickel (Ni) alloys are the most widely useful alloy material for various applications. The applicability is due to their excellent resistance to work in saltwater corrosion. The alloy is capable of dealing with macrofouling and excellent fabricability effectively. Also, Cu Ni products are popular due to their high durability, antimicrobial properties, and elegant appearance. It is a well-defined product that follows all the national and international raw material quality standards. Also, the product is available with different specifications and demands. Cu Ni Pipes are useful in the saltwater piping system due to their complete resistance to fouling and marine organism. The Copper Nickel Pipes are efficient in condenser tubes, the heat exchanger of desalination plant evaporator. Also, in thermal power plant and their air-cooling areas. 

Benefits of using Cu Ni Pipes

Copper-Nickel Seamless Pipes hold various advantages and features over other piping materials. Due to the effectiveness in the production of Cu Ni pipes, it becomes popular. Cupro Nickel 70/30 Pipe is a high-quality alloy that offers outstanding qualities such as high tensile strength, reusability, and unique forming ability. Cu Ni Pipes are highly resistant to mechanical stress, give higher resistance to work at a higher temperature, and resist high-pressure conditions.

Applications of Cu Ni pipe

  • Ship construction and its repair

An alloy of copper and nickel is useful in seawater cooling, firefighting instruments, pneumatic and chilling systems, bilge and ballast, and sanitary. These Cu Ni pipes are also appliable for the cargo tank heating coils and the desalination units’ feed line.

  • Desalination plants

Cu Ni pipes are useful in high temperatures involving desalination units. Here, Cu Ni pipes are the most helpful desalination plants. Also, Cu Ni pipes are useful in the recovery section and heat rejection points. These pipes work in brine heaters. Cu-Ni alloy pipes are helpful for evaporator tubing.

  • Power generation

Cu-Ni pipes and alloy components are applicable easily into the steam turbine condenser and cooling systems of oil. Also, these pipes are useful in applications requiring more significant pressure. The pre-heaters of the fossil fuel power plants, nuclear power generation stations, and the auxiliary cooling system requires high pressure and temperature. The Cu Ni pipes are useful in the transfer of clean seawater and brackish water. Cu Ni alloy exhibits more significant benefits in marine renewable energy generation plants such as tidal devices, wind farms, and waves.

Applications And Advantages Of Copper Pipes

Copper pipe is a versatile product with its high strength, superior corrosion resistance, and outstanding thermal efficiency, as well as with the ability to conform to any kind of requirement, this makes it an almost ideal metal that is necessary for our daily life.

Advantages of Copper Pipe

  • They have high strength and exceptional thermal capabilities that are nearly 8 times greater than aluminum.
  • Copper Nickel Pipes can tolerate corrosion a great deal higher than maximum different metals.
  • Copper Pipe may be very sturdy and might manage the peculiarities of the climate well. It is unaffected via way of means ultraviolet radiation and does now no longer belch out dangerous poisonous gases withinside the case of a fire because it has advanced resistance to burning.
  •  Copper Pipe may be joined with solder to supply solid, long-lasting joints. Copper Pipe is environmentally sustainable and might effortlessly be recycled.

Automotive Industry

The superior resistance to corrosion and suitable machinability of these pipes meet increasing demands on safety and production optimization in the automotive industry. Automotive electrical and electronic components require laminated copper products for connectors, cable lugs, terminal blocks, relays, and drive motors.

Communications Equipment

  • Communication equipment The copper tube is the core of the so-called high-frequency coaxial cable used in telecommunications. Transmitting antennas for mobile telecommunications are equipped with these high-frequency coaxial cables. To ensure low loss transmission from the transmitter to the antenna mast and from the antenna to the Receiver, internal and outer conductors crafted from a tube, product of excessive conductivity styles of copper, are used.
  • Architecture- For generations, copper has been used withinside the layout of roofs and facades. Besides the cultured aspects, concerns of the financial system and the choice for natural, environment–pleasant substances result in the selection of copper. The sturdiness of copper, its appeal, and its true processing features have made it a crucial factor in discerning architecture.
