Aluminium Clad Copper tube(called ACC tube) can be used in the fields of Air-conditoner,Refrigeration,Heat Exchaner,Solar warter Heater and Water Pipe etc.The our layer of ACC tube is antirust Aluminium Alloy,the inner layer is copper,and the middle layer is the Metallurgy integrated Layer of copper and Aluminium.Copper and Aluminium have special advatages on heat transferring and heat exchange,which establishes a base of well heat exchange.
For usage,the fabrication and process of ACC tube are similar to pure copper tube,and the well fabrication capability and compatibility are the bases of ACC tube being accepted by the market.
For heat exchange efficiency,the air-conditioner of ACC plain tube can be equivalent to the Air-conditioner of inner groove copper tube,and the efficiency of air-conditioner with inner grooved ACC tube can be increased about 5%.On energy saving,ACC tube can well avoid the electrochemical corrosion between copper tube an aluminium foil in the air-conditioner now,and release the decrease of heat exchange efficiency year by year.
On cost performance,the same length and size tube,the weight of ACC tube is just the 40% of traditional copper tube,low cost helps to tube users take up the market.
The broken strength of ACC tube is 110-130Mpa,blast pressure all 180 MPa above,the expanding rate of the mouth can reach 40%-50%,the index of inner face, press flat,curve and anti-leaking all gain the requirement of the ACR tube standard. The rate of tube cut section area is 12%-14%,weight rate is 31-38%,normal specific gravity is 3.45g/cm3.
The main size of ACC tube is the five kinds as below,can suplly in the shaft or pancake tube types:φ9.52×0.5mm，φ7.94×0.5mm；φ7×0.5mm.
