The application of copper in various fields:
Electric vacuum devices: mainly high-frequency and frequency emitting tubes, waveguides, magnetrons, etc., which require high-purity oxygen free copper bends and dispersed oxygen free copper bends.
Energy industry: In thermal and atomic power generation, steam is used for work, and the main condenser consists of tube sheets and condenser tubes. Due to the good thermal conductivity and resistance to water corrosion of copper, the bent pipes here are made of pot brass, aluminum brass, or white copper. In addition, the utilization of solar energy also requires the use of many copper bend pipes.
Petrochemical industry: Copper and many copper alloys have good corrosion resistance in aqueous solutions, non oxidizing acids such as hydrochloric acid, acids (such as acetic acid, citric acid, fatty acids, lactic acid, oxalic acid, etc.), various bases other than ammonia, and non oxidizing compounds (such as oils, phenols, alcohols, etc.); Therefore, it is widely used in the petrochemical industry to manufacture various pipeline systems that come into contact with corrosive media. Due to its excellent plasticity, copper is particularly suitable for manufacturing heat exchangers with intricate structures and intersecting copper bends in modern chemical industry.
Automotive industry: Copper bend pipes and copper alloy bend pipes are mainly used for radiators, brake system pipelines, hydraulic devices, etc.
Drinking water pipeline: Due to its many advantages such as beauty, easy installation, and hygiene, copper bent pipes have a significantly superior price performance ratio compared to galvanized steel pipes and plastic pipes. In residential and public buildings, materials used for water supply, heating, gas supply, and sprinkler systems are increasingly favored by people and have become the current choice. In developed countries, copper bend pipes have accounted for a large proportion in water supply systems.
