What are the characteristics and uses of copper tubes?
Red copper tubes have very high requirements for the purity of copper. The copper content generally must be more than 99.95%. A very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. Therefore, red copper tubes have Performance advantages over other pipes. So, do you know what the characteristics and uses of copper tubes are? The editor of Ruiqi has made a detailed summary for everyone today. Let's take a look at it together.
1. Characteristics of copper tubes
1. Hard texture
Copper pipes are harder than plastic pipes and have the high strength of general metals (the strength of cold-drawn copper pipes is equivalent to steel pipes of the same wall thickness). It is not easy to corrode, is resistant to high temperature and high pressure, and can be used in a variety of environments. The main material of copper pipes is copper. The melting point of copper is as high as 1083 degrees Celsius. The temperature of the hot water system is insignificant to copper pipes, so as long as it is used correctly, there is no need to worry about safety issues.

2. Durable
Copper has stable chemical properties, integrating cold resistance, heat resistance, pressure resistance, corrosion resistance and fire resistance (the melting point of copper is as high as 1083 degrees Celsius), and can be used in different environments for a long time. The service life of copper pipes can be as long as the life of the building, or even longer.
3. Can withstand extreme temperatures
The copper tube can withstand extremely cold and hot temperatures. It has a wide application range from -196°C to 250°C and can adapt to drastic changes in temperature (-high temperature-low temperature-high temperature-). Its performance will not be affected by long-term use and severe temperature changes. It decreases due to changes and will not cause aging, which is beyond the reach of ordinary pipes.
4. Safe and reliable to use
Copper tubes are easier to bend than ordinary metals, have good toughness and high ductility, and have excellent vibration resistance, impact resistance and frost heave resistance. The linear expansion coefficient of the copper tube is very small, which is 1/10 of that of the plastic tube. It is fatigue-resistant and will not cause excessive thermal expansion and contraction when the temperature changes, causing stress fatigue cracking.
5. Good for health
When choosing or renovating a house, few people ask about the water supply pipes of the house. In fact, the material of water supply pipes will greatly affect people's health. Copper water pipes have strong sterilization and disinfection capabilities. E. coli in the water supply will no longer reproduce in the copper pipes. More than 99% of the bacteria in the water will disappear after entering the copper pipes for 5 hours. This biological performance lies in the fact that there are trace amounts of copper ions dissolved in the water in the copper pipes, and copper ions have strong bactericidal ability.
2. Purpose of copper tube
1. Copper tubes are often used in heat exchange equipment (such as condensers, etc.). It is also used to assemble low-temperature pipelines in oxygen production equipment. Small-diameter copper pipes are often used to transport pressured liquids (such as lubrication systems, oil pressure systems, etc.) and pressure measuring tubes used as instruments.
2. The corrosion resistance and ease of processing of red copper can be welded and brazed, allowing it to be processed into pipes, strips, foils, pipes, rods, wires, wire rods, heterogeneous copper materials and copper castings, etc.
3. T1 and T2 copper tubes are mainly used as conductive, thermal conductive and corrosion-resistant components, such as wires, cables, conductive screws, shells and various conduits. T3 copper is mainly used as structural materials, such as making electrical switches, washers, rivets, nozzles and various conduits, etc. It is also commonly used in some less important conductive components.
