The manufacturing process of air conditioning copper pipes goes through several steps: First, manufacturers purchase high-quality copper materials, which are carefully screened and tested to ensure that they have excellent thermal conductivity and corrosion resistance. Next, the copper is machined to the desired diameter and wall thickness, usually using a copper tube rolling or drawing process. In the process of rolling or drawing, cold drawing, pickling and annealing are also needed to improve the mechanical properties and surface finish of copper pipes. Finally, after cleaning, packaging and quality inspection steps, air conditioning copper pipe can enter the market
