The red copper tee is mainly made of red copper. Red copper is a high-purity copper material, also known as copper or cuprous copper due to its purple color.
Red copper has very good electrical conductivity and ranks second only to silver among all metals, which enables the red copper tee to have certain applications in the electrical industry.
It has excellent thermal conductivity and can effectively promote the heat exchange of the refrigerant. For example, in an air conditioning refrigeration system, it can improve the refrigeration efficiency.
Red copper has good corrosion resistance in the atmosphere, seawater, certain non-oxidizing acids (such as hydrochloric acid, dilute sulfuric acid), alkalis, salt solutions, and various organic acids (such as acetic acid, citric acid), ensuring long-term use.
Red copper is rich in ductility and can be processed into various semi-finished and finished products through cold and hot plastic processing to meet the processing needs of different shapes and sizes.
Some red copper tees are made by the welding process, ensuring the firmness and tightness of the connection and being able to withstand high pressure and low-temperature environments, maintaining stable working conditions for a long time.
Extruded red copper tee fittings are processed according to the principle of plastic deformation of metals. Solid or liquid media are filled in the original pipe blank, and the red copper metal in the pipe blank undergoes plastic flow in the die cavity under the axial extrusion force, supplemented by other shaping processes. It can be divided into three forms: hot extrusion, cold extrusion, and warm extrusion.
Red copper tees are made of high-purity copper, which features excellent electrical and thermal conductivity, good corrosion resistance in various media (such as seawater and dilute acids), and strong ductility that allows easy forming and processing.
Thanks to its outstanding thermal conductivity, the red copper tee efficiently facilitates heat exchange. In refrigeration and air conditioning systems, this property directly enhances overall cooling and refrigeration efficiency.
Red copper tees are manufactured using two primary methods: the welding process, which ensures strong, leak-proof connections under high-pressure conditions, and the extrusion process (cold, warm, or hot extrusion) which shapes the fittings via metal plastic deformation.
Yes, red copper has high corrosion resistance against atmospheric conditions, seawater, non-oxidizing acids (like hydrochloric and dilute sulfuric acid), alkalis, salt solutions, and organic acids, making it highly durable for long-term use.
They are widely applied in plumbing, refrigeration and HVAC systems, the electrical industry, petrochemical piping, shipbuilding, and medical gas supply copper pipelines.
