Corrosion-resistant phosphorus deoxidized copper tube (grades TP1/TP2 (more commonly used)) are manufactured using a phosphorus deoxidation process, with a residual phosphorus content of approximately 0.015-0.04%. They possess excellent weldability and cold bending performance, making them suitable for applications requiring high machinability and corrosion resistance. These copper tubes not only exhibit excellent resistance to hydrogen embrittlement, effectively preventing embrittlement caused by hydrogen in high-temperature and high-pressure environments, but also ensure long-term stable operation of the piping system.
Corrosion-resistant phosphorus deoxidized copper tubes are widely used in refrigeration and air conditioning systems as connecting tubes for refrigerant transport. Due to their excellent thermal conductivity, the copper tubes efficiently transfer heat, ensuring the efficient operation of the refrigeration system. The corrosion resistance of the copper tubes ensures they are not easily damaged by environmental factors during long-term operation, reducing maintenance costs. For gas and plumbing fittings, the corrosion resistance of phosphorus-deoxidized copper tubes maintains good performance and stability under the long-term influence of water, gases, and chemical media, ensuring the safety and reliability of the system. In heat exchanger piping, copper tubes' excellent thermal conductivity and corrosion resistance make them an ideal piping material for heat exchange systems, helping to improve heat exchange efficiency and extend equipment lifespan.
These copper tubes also possess excellent weldability, easily withstanding high-temperature welding processes to ensure the strength and sealing of joints. Due to their good cold-bending properties, copper tubes can be easily bent and adjusted to meet the needs of complex installation environments, improving construction efficiency.
