Air conditioning copper tube can be roughly divided into ordinary air conditioning copper tube and degreased air conditioning copper tube.
Ordinary air conditioning copper pipe: the thickness is generally 2 points, 3 points of pipe 0.5mm thick, 4 points 0.6mm thick, 5 points and 6 points 0.7mm thick. Mainly used for R22, pressure control at 0.98MPa;
Degreased air-conditioning copper tube: also called "degreased air-conditioning copper tube", there are 2 points, 3 points tube is 0.8mm thick, 4 points, 5 points, 6 points is 1.0mm thick. Mainly used for R410 and other new refrigerant, pressure control at 1.8MPa;
Air conditioning copper pipe material specific classification
Oxygen-free copper: including high-purity oxygen-free copper (TU0, TU1, TU2) and phosphorus deoxidized copper (TUP, TP1, TP2, etc.), containing very trace amounts of oxygen and some impurities, but the overall oxygen content is not greater than 0.003%, and the purity of copper is greater than 99.95%. Oxygen-free copper products are mainly used in the electronics industry, like audio equipment, vacuum electronics, cables, etc.
Special copper: arsenic copper, silver copper, tellurium copper, etc., characterized by the addition of different trace alloying elements, such as containing As, Ag, Te, etc., in order to achieve the purpose of enhancing the overall performance of the material.
Oxygenated copper: mainly ordinary pure copper (T1, T2, T3, etc.) and tough copper, containing oxygen also contains deoxidizer residues of pure copper, characterized by the opposite of oxygenated copper.
Brass tube: copper-zinc alloy tube, the number after the letter H in the grade often represents the middle value of its copper content, zinc content for the rest of the amount. Different grades of brass tubes, with higher and higher copper content, overall show better quality and extension properties, mainly used as water pipes and water-related connections.
Copper tube: our refrigeration industry with the copper tube is copper, copper content of 99.90% or more, with copper metal, the good characteristics of this high-quality base class metal, widely used in various fields of industry and civil use, and play an important role. Mainly TP2, T2, TU1 three categories.
