B10 white copper pipe is a copper-nickel alloy pipe, in which the content of nickel is about 10%, and the rest is mainly copper with a small amount of other elements. Due to its good corrosion resistance, mechanical properties and process properties, it is widely used in many fields. The following is the introduction of its main application scope:
Marine engineering and shipbuilding
Seawater system: It is used to manufacture seawater cooling pipes, heat exchangers, condensers, etc. for ships. Seawater is highly corrosive, and B10 copper tubes show excellent corrosion resistance in seawater, which can effectively resist the erosion of seawater and prolong the service life of the equipment.
Marine engineering equipment: such as seawater treatment pipelines on marine platforms, the shell or internal pipe fittings of marine exploration equipment, etc., which can work stably in the marine environment.
Petrochemical industry
Corrosive media transportation: used to transport petroleum, chemical raw materials and media containing corrosive components (such as acid, alkali, salt solution, etc.). For example, it can be used in oil refineries to connect the pipelines of distillation towers, reaction kettles and other equipment, or as the lining material of chemical containers.
Heat exchange equipment: as a heat exchanger pipe, using its good thermal conductivity and corrosion resistance, in high temperature, high pressure and corrosive conditions to achieve heat exchange.
Power industry
Power station condenser: In thermal power plants, it is used to make pipes for condensers that condense steam into water. Its corrosion resistance prevents the corrosion of piping by impurities in the circulating water and ensures the normal operation of the power station.
Other power equipment: such as some of the corrosion-resistant piping or related components in nuclear power plants, which can be used in specific corrosive environments.
Heat exchange and refrigeration equipment
Air conditioning and refrigeration systems: as the evaporator, condenser tubes, in the refrigeration cycle to withstand the corrosion of refrigerants and water, while playing a good thermal conductivity.
Industrial heat exchanger: used for heat transfer of high temperature or corrosive medium in heat exchange equipment in food processing, pharmaceutical, metallurgy and other industries.
Mechanical Manufacturing and Instrumentation
Precision mechanical parts: can be processed into bushings, valves, pump impellers and other mechanical parts, the use of its strength and corrosion resistance to meet the performance requirements of mechanical operation.
Instrumentation fittings: Used to manufacture connecting fittings or measuring elements for pressure gauges, flow meters and other instruments to ensure the accuracy of measurement and reliability of equipment in complex environments.
Construction and decoration field
Building water supply and drainage: used for laying water supply and drainage pipes in some buildings that require high corrosion resistance, especially suitable for coastal areas or areas with poor water quality.
Decorative materials: Because of its beautiful silver-white metallic luster, it can be used as decorative pipes for architectural decoration projects, such as balustrades, handrails and decorative lines.
Other fields
Medical devices: In some medical devices that require corrosion resistance, such as certain pipes or parts that come into contact with body fluids, B10 copper alloy tubes can be used for manufacturing.
Chemical experimental equipment: used to manufacture corrosion-resistant reaction containers, pipes or fittings in laboratories to meet the requirements of corrosion resistance in chemical experiments.
Summary of Advantages of B10 White Copper Tubing
Advantageous features

With its comprehensive performance advantages, B10 copper tubes have been widely used in occasions requiring corrosion resistance and certain mechanical properties, and with the development of technology in various industries, its scope of application may be further expanded.
Comparison of the composition and material properties of B10 white copper tubes and other fittings
B10 white copper tubes Copper (approx. 90%) + nickel (approx. 10%) + a few alloying elements Copper-nickel alloy gives excellent resistance to seawater and salt spray corrosion, with well-balanced mechanical properties, both toughness and strength.
Pure copper tubes (purple copper / brass) Pure copper (≥99%) or copper-zinc alloy Pure copper has excellent thermal conductivity (thermal conductivity of about 400W/m・K), but corrosion resistance is average; brass (copper-zinc alloy) has high strength, but is susceptible to stress corrosion in seawater or ammonia environments.
Stainless steel tube (such as 304/316) iron + chromium (≥ 10.5%) + nickel (304 contains 8% nickel, 316 contains molybdenum) atmospheric and acid corrosion resistance, 316 in seawater corrosion resistance is close to B10, but the thermal conductivity is poor (about 16W/m・K), work hardening is obvious.
Carbon steel pipe Iron + carbon (≤ 2%) + a few impurities High strength, low cost, but poor corrosion resistance, easy to rust, need to be coated with anti-corrosion layer, not for corrosive media.
Aluminum alloy tube Aluminum + magnesium, silicon, copper and other alloying elements Lightweight (density of about 2.7g/cm³), resistant to atmospheric corrosion, but less resistant to seawater and chemical media corrosion, lower strength.
