Although copper pipes are small cold room accessories, many times the quality of it may be ignored. However, copper tubes are also important in the construction of cold storage, as improper selection can have an impact on the use of a cool room. So how is the cold storage copper tube equipped?
I.Why choose copper pipes?
1. Copper pipes have strong, corrosion-resistant characteristics. Therefore, it has become the first choice of modern contractors for the installation of water pipes, and heating and cooling pipes in all residential commercial houses.
2. Copper tubes are economically priced. As it is easy to process and connect, it makes it possible to save on materials and total costs when installing them. Stability can be reliable purple copper pipe sex, which can save maintenance costs.
3. Copper tubing is compact and lightweight. For the same inner diameter of stranded threaded pipe, it does not require the thickness of ferrous metal. When installed, it is less expensive to transport, easier to maintain, and takes up less space.
4. Copper pipes can easily change shape. Because it can be bent and deformed, it can often be made into elbows and joints. The smooth bend allows the tube to be bent at any angle.
5. Copper tubes are easy to connect and safe. It does not leak, is non-flammable, does not produce toxic gases, and is corrosion-resistant.
II. How to select copper pipes?
1. Generally in the purchase will need to observe the appearance of the copper tubes to determine, first of all, is to see the color of it. According to the type of copper tubing purchased to do different color judgment, such as purple copper pipe, the general color reddish red copper is good copper. Brass pipes, the general color of lighter to be better. There is also a layer of zinc plated on top of the copper, some galvanized, the color of white is better. There is also a kind of poor quality copper, the copper tube inside impurities, with a hand bend broken into two, inside the black impurities do not buy.
2. Feel the inner and outer walls of the copper tube with your hands to see if it is smooth and clean, and see if there are defects such as sand holes, oxidation, and rupture. If you are not sure, you can use sharp objects to scrape the top, generally good copper pipes are processed using pure copper. There will be a better extension, so quality copper tubing will have a deep line appear. After scratching inside it, if it is the same as the outer wall, it shows that the overall quality of this part is relatively high. But if the color or other aspects are different, there is a good chance that something like iron has been added to the inside. However, better copper tubes are used more in the military industry and other special industries.
3. Generally speaking, copper pipes are processed and formed into hard, semi-hard, and soft forms. The flexibility of the different forms also varies, and can generally be determined by bending it. High-quality copper tubing is very easy to bend off, but if it is difficult to bend or bend after there will be cracks appear, indicating that the quality of copper tube parts is not too good.
III. What should you pay attention to when using copper pipes?
1. The selection of copper tube diameter should be in strict accordance with the compressor suction and discharge valve interface selection of pipe diameter when the condenser and compressor separation of more than 3 meters should increase the diameter of the pipeline.
2. All copper pipes of the copper outlet of the cold storage unit should be worn separately from the insulated pipes. All copper tubing need to be separately dressed with insulated tubes together with electric wires in the same direction together with air-conditioning ties, try to straighten the pipes and fix them in sections.
3. Wires and copper pipes should be used to connect the cold storage refrigeration units, electrical control systems, and other components. The connecting pipes should be tightly connected and have appropriate insulation and protection measures.
4. The joints between the insulated pipes and the insulated pipes are to be tightly closed with electrical tape.
