Hot Air Conditioner Copper Aluminum Connecting Tube

"Air conditioner copper aluminum connecting tube"One end or both ends of the pipe are connected to a copper pipe, forming the ctructure of the copper-aluminum(-copper) joint,which are used for the tranmission of refrigerant in the refrigaration system.The thinner copper pipe is inserted into the thiker aluminum pipe, by resistance welding with any weld flux produce a copper - aluminum joint pope.MAIN PERFORMANCE INDEX OF COPPER ALUMINIUM AIR ConDITIONER ConNECTION TUBEPerformance indexparameterspressure test4.9Mablasting test≥13MaThe lenth of welding fusion of copper-aluminum≥5mmleakage rate of welding joint≤10ppmtensile strength of welding joint≥60Maelongation at break of welding joint≥22%
