Copper-aluminum connecting pipe (1)Copper tube:OD:1/4,&3/8,&1/2,&5/8,&3/4, (2)Length:3,4,6,7,10,15,20M (3)Color: white (4)port: shanghai (5)payment terms: T/T, L/C. (6)Length can be determined according to the needs of buyers Copper-aluminum connecting pipe features: The copper-aluminum connecting pipe electrochemical corrosion does not exist, no solder or other high temperature melting point of copper and aluminum, all metal anaerobic adhesive contact surface and sealing liquid insulation, completely solve the copper-aluminum connecting pipe in the air conditioning industry, the practical application of the hidden problems; low cost, easy to bend, easy to protect; reliable, comprehensive specifications. Copper-aluminum connecting pipe in air conditioning manufacturing, air conditioning maintenance is the application. A long life: the outer surface of copper-aluminum connecting pipe with a cross-linked polyethylene (hot pipe) so antiseptic treatment to ensure the separation of water and moist air on the corrosion of aluminum tubes, life is more than 20 years. Second, low cost anti-oxidation: copper-aluminum connecting pipe ends and the valve does not exist Jiechu oxidation corrosion and so easy to produce quality risk, copper and aluminum pipe to connect both ends of the brass, to avoid the occurrence of this problem and achieve a lower cost purpose; because it is cold take technology to complete, so also there is no other way of heat or other solution exists to complete the connection prone to electrochemical corrosion of solder joints, leading to leakage of tube wear eye. Third, high cleanliness: as between copper and aluminum pipe without welding, but by cold access connection, to avoid all the high-temperature welding caused by the surface oxide production, so do not need any treatment can achieve cooling pipe The cleaning requirements. 4, good insulation properties: air conditioning is needed to connect pipe insulation, and to improve the air conditioner's energy efficiency, should further improve the connection pipe insulation performance. The thermal conductivity of copper is 1.8 times of aluminum, together with the outer layer for corrosion prevention and control cross-linked polyethylene pipe insulation effect, so a copper-aluminum connecting pipe will help connect pipe insulation, reducing the cold waste, improve the energy efficiency level. 5, safety performance: copper-aluminum connecting pipe bursting pressure and allow the copper connecting pipe burst pressure to allow the same design pressure are 13.0Mpa, 13.0Mpa is the air pipe system 3 times the maximum working pressure, so the use of copper and aluminum connecting pipe will not be any wounding event. 6, bending excellent performance, easy to install, move machine: aluminum than brass soft, copper-aluminum connecting pipe copper tube design is 1.5 times the wall thickness, not only to ensure strength and relative connecting copper pipe is easier to install and transfer machines. Copper-aluminum connecting pipe 1)Copper tube:OD:1/4,&3/8,&1/2,&5/8,&3/4, (2) Length:3,4,6,7,10,machines.
