ASTM B111 C70600 O61 Copper Nickel Alloy Low Finned Tube For Heat Exchanger
In the ASTM B111/B111M-18 standard, the requirements for C70600 white copper tube BFe10-1-1 heat exchange tube are very strict. Among them, there are detailed regulations on the composition, structure, performance, size, and shape of materials. The EN12451 standard proposes corresponding execution standards for the European market, mainly including chemical composition, physical properties, mechanical properties, non-destructive testing, and other aspects.
In addition to the above two standards, there are also relevant domestic standards, such as GB/T 8890-2018, which have strict regulations on the material appearance, composition, mechanical properties, dimensional tolerances, and other aspects of C70600 white copper tube BFe10-1-1 heat exchange tube.
In summary, the implementation of standards is crucial for the quality control, performance evaluation, and technical application of C70600 white copper tube BFe10-1-1 heat exchange tube. Enterprises must strictly follow the standards during the production process to ensure product quality.
C70600 white copper pipe
Due to its excellent corrosion resistance, white copper is mainly used in key industrial fields such as seawater desalination evaporation pipes, central air conditioning condenser pipes, ship air coolers, petrochemical coolers, and power plant steam turbine condensers. White copper is a copper based alloy with nickel as the main additive element, which is silver white and has a metallic luster, hence the name white copper. Copper and nickel can dissolve each other infinitely to form a continuous Solid solution, that is, regardless of the proportion of each other α-- Single phase alloy. When nickel is melted into red copper with a content of D200 exceeding 16%, the resulting alloy becomes relatively white like silver in color. The higher the nickel content, the whiter the color. However, after all, it blends with copper. As long as the nickel content ratio does not exceed 70%, the yellow color of copper can be seen with the naked eye. Moreover, the nickel content in white copper is usually 25%.
C70600 copper nickel alloy has excellent corrosion resistance to clean or polluted seawater and river water, and is widely used in heat exchangers that use seawater in power plants, desalination, petrochemical plants, and other industries.
