How are air conditioning copper pipes made?
- Copper material preparation: The first step in manufacturing air conditioning copper pipes is to prepare the copper material. High-purity copper is usually used as the raw material, which helps ensure the thermal conductivity and corrosion resistance of copper pipes. The copper block is heated to a sufficient temperature and then rolled, drawn or extruded to form a preliminary copper tube shape.
- Cold rolling and hot rolling: Copper pipes are cold rolled or hot rolled to adjust the diameter and wall thickness of the pipe. Cold rolling is generally used to produce thin-walled tubes, while hot rolling is used to produce thicker tubes.
- Annealing treatment: In order to improve the plasticity and thermal conductivity of copper pipes, copper pipes usually undergo an annealing treatment process. This involves heating copper pipes to a certain temperature and then slowly cooling them.
- Cleaning and Coating: Copper pipes may have some oxides or impurities on their surface, so they need to be cleaned. In some cases, copper pipes may also be coated to improve their corrosion resistance.
- Pipe Cutting: Copper pipe is often cut to appropriate lengths to meet the needs of different applications.
- Forming and Welding: Copper tubing can be formed in a variety of ways, such as bending, flaring, or constricting, to suit specific system designs. The connection points are usually soldered to ensure a strong connection.
- Testing and Quality Control: Once manufactured, copper tubing may undergo a variety of tests, including dimensional inspections, pressure testing and non-destructive testing, to ensure it meets specifications and quality standards.
