C70600 copper tube is a kind of copper-nickel alloy tube, also known as white copper tube, and the following is a brief introduction about its usage environment, corrosion resistance and product characteristics:
Usage environment
Seawater environment: C70600 copper tube is widely used in the field of marine engineering and shipbuilding due to its excellent seawater corrosion resistance. For example, in the seawater cooling system of ships, it is used to convey seawater to cool the engine and other equipments; in the seawater desalination device, it is used as a heat exchange pipe to realize the transfer of heat.
Chemical environment: in chemical production, there are various corrosive media, such as acid, alkali, salt solution, etc. C70600 copper tube is able to work stably in some acid and alkali environments with moderate concentration and temperature, and it can be used in heat exchanger, pipeline and other parts of chemical equipments, such as in the process of production of some organic acids, to undertake the task of material transportation and heat exchange.
Thermal power plant environment: In the circulating water system of thermal power plant, C70600 copper tube can be used as the heat exchanger tube of condenser. Circulating water usually contains a certain amount of dissolved oxygen, microorganisms and other impurities, C70600 copper tube can resist the erosion of these substances to ensure the normal operation of the heat exchange system.
Corrosion resistance
Seawater corrosion resistance: C70600 copper tube contains about 10% of nickel, the addition of nickel significantly improves the corrosion resistance of copper in seawater. It can form a layer of dense oxide film on the surface of seawater, preventing seawater from further reacting with the base metal and effectively preventing the occurrence of pitting corrosion, crevice corrosion and stress corrosion cracking and other forms of corrosion.
Chemical corrosion resistance: it has good resistance to some chemical substances, such as in dilute sulfuric acid, hydrochloric acid and other non-oxidizing acids, as well as some alkaline solutions and salt solutions, it can maintain good corrosion resistance. However, it should be noted that its corrosion resistance will be affected by factors such as medium concentration, temperature and flow rate.
Anti-microbial corrosion: Due to the special properties of its surface, C70600 copper tube is not easy to be attached and eroded by microorganisms, and has better anti-microbial corrosion resistance compared with some other metal materials in water environments containing microorganisms, which reduces the risk of pipeline damage and leakage caused by microbial corrosion.
Product Characteristics
Good thermal conductivity: Although C70600 copper tubing is a copper-nickel alloy, it still maintains a high thermal conductivity, which enables effective heat transfer and is suitable for a variety of applications requiring efficient heat transfer, such as heat exchangers, condensers and other equipment.
Higher strength and toughness: high tensile strength and good toughness, so that it is not easy to rupture or deformation when subjected to a certain pressure and mechanical stress, can adapt to different installation and use conditions, to ensure the reliability and stability of the equipment.
Good processing performance: it is easy to carry out cold and hot processing, such as bending, stretching, rolling, etc. It can be made into various shapes and specifications of pipes to meet the needs of different projects. It also has good welding performance, which is easy for installation and maintenance.
Aesthetics: C70600 copper tube shows silver-white metallic luster, which is aesthetically pleasing, and can also be used as decorative tubing in some occasions where appearance is required, such as architectural decoration and landscape projects.
