Copper tube refers to copper material made by pressing or drawing copper. Due to its strong and wear-resistant characteristics, it is often used in the electrical, industrial and construction industries. Copper tubes can be produced by extrusion, continuous casting and rolling, and up-drawing. Copper tubes are important raw materials for the processing and manufacturing of refrigeration equipment. They have two main uses:
Making heat exchangers;
Making connecting pipes and pipe fittings.
1. Classification of copper tubes
1. Air conditioning copper tubes can be roughly divided into ordinary air conditioning copper tubes and degreased air conditioning copper tubes:
Ordinary air conditioning: The thickness is generally 0.5mm for 2-point and 3-point tubes, 0.6mm for 4-point, and 0.7mm for 5-point and 6-point. Mainly used for R22.
Degreased air conditioning copper tube: also called "degreased air conditioning copper tube", 2-point and 3-point tubes are 0.8mm thick, 4-point, 5-point, and 6-point are 1.0mm thick. Mainly used for refrigerants such as R410.
2. Specific classification of air conditioning copper tube materials:
Oxygen-free copper: including high-purity oxygen-free copper (TU0, TU1, TU2) and phosphorus deoxidized copper (TUP, TP1, TP2, etc.), characterized by extremely low oxygen content, and a small amount of deoxidizer remains in the deoxidized copper;
Oxygen-containing copper: mainly ordinary pure copper (T1, T2, T3, etc.) and tough copper, characterized by high oxygen content;
Special copper: arsenic copper, silver copper, tellurium copper, etc., characterized by the addition of different trace alloy elements to achieve the purpose of improving the comprehensive performance of the material.
