How to distinguish the advantages and disadvantages of copper pipes used in chillers

Copper pipe is an important material component of the chiller . In the evaporator, condenser, and connecting pipe, the quality of the copper pipe directly affects the service life and cooling effect of the chiller. Today, Davos teaches everyone to understand copper. The pros and cons of the tube.

1. Generally, in the procurement, it is necessary to observe the appearance of the copper tube to judge. The first is to look at the color of the copper tube. According to the type of copper tube purchased, different colors are judged. For example, the copper tube is generally reddish red. copper. Brass tubes, generally lighter in color, are better. There is also a layer of zinc on the copper, some galvanized, and the color is white. There is also a kind of inferior copper. There are impurities in the copper tube. If you bend it with your hand, you will break into two pieces. If there is black impurities inside, don't buy it.

2, secondly, touch the inner and outer walls of the copper tube by hand to see if it is smooth and clean. See if there are any defects such as blisters, oxidation, cracking, etc. If you are not at ease, you can scrape the top with sharp objects. Generally, the good copper tubes are pure. Copper is processed to have a better extension, so a high quality copper tube will have a deep line. After the copper tube is drawn, if it is the same as the outer wall, it indicates that the overall quality of the copper pipe is relatively high. However, if the color or other aspects are different, it is very likely that some substances similar to iron are added to the inside. However, better copper pipes are used in the military industry and its special industries.

3. The copper tube which is generally processed and formed is mainly divided into three types: hard state, semi-hard state and soft state. The flexibility of different forms is also different. Generally, it can be determined by bending a copper tube. The high quality copper tube is very It is easy to bend, but if it is difficult to bend or bend, there will be cracks, indicating that the quality of the copper fittings is not very good.
