How to distinguish between copper tube or aluminum pipe?
Copper is yellow and aluminium is whiteIf it is copper plated, cut the tube and see the fracture to see whether it is copper plated
I am back to a repair is already installed. I worried about this version is not the original version, tangled ah, he said can Quanguolianbao 3 months but you have to take what I call if I give evidence of bad warranty can be taken directly that you can trustChasing the answerIs it mainly made of copper tubes into aluminum tubes now?. If it is, you can ask for replacement, the aluminum pipe is not innate than copper tube, especially for a long time, the aluminum tube is easy to punch.
If it is not installed, weighing, the copper tube is much heavier than the aluminum tube. There is opened the insulation pipe joint at 10 cm behind the place if there are traces of welding pipe, and the outside layer of plastic sheath wrapped, if it is, if not sure is aluminum, copper can be easily resolved. After installation, the air conditioner is only identified by the latter method.
