What’s the difference between hard copper tube and soft copper tube?
Copper tube, a kind of non-ferrous metal tube, is a seamless tube pressed and drawn. It is characterized by light weight, good thermal conductivity, high low temperature strength and corrosion resistance. Because of these excellent properties of copper pipes, the use of copper tubes is very common. So in the process of using, what are the differences between hard copper pipes and soft copper pipes?
Hard copper tubes are made by drawing or extruding copper pipes without artificial treatment, so that they can be formed naturally. At this time, the structure of the copper pipe is already full. This kind of copper tube is easier to crack and not suitable for bending. Therefore, the hard copper pipe is generally straight tube.
The manufacturing method of soft copper pipe is almost the same as that of hard copper pipes, that is, annealing process is added compared with hard copper tubing. Copper tube annealing is to calcine in high temperature furnace, so that the arrangement of elements in the copper pipe changes. But after annealing, the copper pipe will become soft, so it is more convenient to bend, so the copper pipe produced is called soft copper tube.
Hard copper pipe can only be used as straight tubes and can not be bent, so they are generally used in power plants, electrical equipment switches, and there are some places where the connection points are far away and need not be bent. Compared with soft copper tubes, the price will be lower. Although the name of the soft copper pipe is soft tube, it can also be used as hard tubing, so the soft copper tube can be used in more places, and can be used in a straight tube way, as well as in a coil way. Coil can make the length of copper pipe longer, if the connection point is longer, it can be intercepted according to the length at will, so as to prevent the occurrence of leaks in the welding of copper pipe. Soft copper pipes are often used in refrigerators, air conditioners and other places where bending pipes are needed.
