Copper tubes, also known as red copper tubes, are a type of non-ferrous metal tubes. They are pressed and drawn seamless tubes. Copper tubes are strong and corrosion-resistant and can be used in a variety of environments. So how do we distinguish the quality of copper tubes when purchasing them?
When purchasing copper tubes, we need to distinguish the quality of copper pipe fittings from the following aspects:
First, we can scrape the surface of the copper pipe fittings with some sharp objects. If the quality of the copper pipe fittings is good, there will be a deep line. Because the ductility of pure copper is very good, pure copper is generally used in military industry production or some special industries.
Second, we can also scratch the surface inside the copper pipe fittings and compare the scratched material with the material just scratched outside. If they are the same, it means that the whole material is still good. If the color is different or there is something else, it means that the material of this copper pipe fitting is relatively poor, and something else may be added inside.
Third, we can bend the copper pipe fittings with force. If it is easy to bend, it is relatively good. If it is very difficult to bend, or if there are cracks inside the copper pipe fittings after bending, then the quality of this copper pipe fitting is relatively poor.
