Product Description
Copper tubes are also called copper tubes. A type of non-ferrous metal pipe, which is a pressed and drawn seamless pipe. Copper pipe has good electrical conductivity and thermal conductivity, and is the main material of conductive accessories and heat dissipation accessories of electronic products, and has become the first choice for modern contractors to install tap water pipes, heating and cooling pipes in all residential commercial buildings. Copper tubes have strong corrosion resistance, are not easy to oxidize, and are not easy to chemically react with some liquid substances, and are easy to bend.
Copper tubes, also known as copper tubes, are pressed and drawn seamless tubes.
The copper tube is light in weight, has good thermal conductivity and high strength at low temperature. It is often used in the manufacture of heat exchange equipment (such as condensers, etc.). It is also used to assemble cryogenic pipelines in oxygen generating equipment. Copper tubes with small diameters are often used to transport pressurized liquids (such as lubrication systems, oil pressure systems, etc.) and pressure measuring tubes used as instruments.
Copper pipe is the modern contractor's first choice for water pipes, heating and cooling pipes in all residential commercial buildings.
1. Since the copper pipe is easy to process and connect, it can save materials and total cost during installation, has good stability and reliability, and can save maintenance.
2. Copper is light. For twisted pipes of the same inner diameter, copper pipes do not require the thickness of ferrous metals. When installed, copper tubing costs less to transport, is easier to maintain, and takes up less space.
3. Copper can change shape. Because copper pipe can be bent and deformed, it can often be made into elbows and joints. The smooth bend allows the pipe to be bent at any angle.
4. Copper is easy to connect.
5. Copper is safe. No leakage, no combustion, no toxic gas, corrosion resistance.
Copper tubes are resistant to high temperatures and can be used in a variety of environments. Compared with this, the shortcomings of many other pipe materials are obvious. For example, the galvanized steel pipes used in residential buildings in the past are very easy to rust, and the running water will turn yellow and the water flow will become smaller after a short period of use. There are also some materials whose strength will decrease rapidly at high temperatures, which will cause unsafe hazards when used in hot water pipes, while the melting point of copper is as high as 1083 degrees Celsius, and the temperature of the hot water system is negligible for copper pipes. Archaeologists have discovered 4,500-year-old copper water pipes inside an Egyptian pyramid that are still in use today.

Copper pipes are durable
The chemical properties of copper are stable, and it combines the characteristics of 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 buildings, or even longer. For example, the copper plumbing installed in Peking Union Medical College Hospital in the 1920s has been in good condition for more than 70 years. It can be seen that the copper pipe is a pipe that has been fully tested by more than one hundred years of time and practical experience.
Copper pipes are safe and reliable
Copper pipes combine the advantages of metal pipes and non-metal pipes. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold-drawn copper pipes is equivalent to that of steel pipes with the same wall thickness); it is more flexible than ordinary metals, has good toughness and high ductility, and has excellent anti-vibration and Impact and frost heave resistance.
Copper tubes can withstand extremely cold and extremely hot temperatures, with a wide range of applications from -196 degrees to 250 degrees, and adapt to drastic changes in temperature (-high temperature-low temperature-high temperature-), and the performance will not change due to long-term use and drastic temperature changes And reduce, will not produce aging phenomenon. This is beyond the reach of ordinary pipes.
The linear expansion coefficient of the copper pipe is very small, which is 1/10 of that of the plastic pipe, and it can resist fatigue. When the temperature changes, it will not cause excessive thermal expansion and contraction, which will cause stress fatigue cracking.
These characteristics make the application of copper pipes in cold regions extremely advantageous. In severe cold areas, the temperature difference between morning and evening is large, and ordinary pipes have a large linear expansion coefficient and low strength, and are prone to stress fatigue cracks due to thermal expansion and contraction. Some claim that it is not brittle at -20 degrees, but in fact it cannot withstand working pressure, and its service life is very short, which has no practical significance. Although insulation measures can be used, it is inevitable to encounter low temperatures during transportation, storage and installation. The performance of the tube is the same at -183 degrees and normal temperature.
copper pipe hygiene
Copper pipes do not have various modifiers, additives, additives and other chemical components of plastic pipes.
Biological research shows that E. coli in water supply cannot continue to reproduce in copper pipes; more than 99% of bacteria in water are completely killed after entering copper pipes for 5 hours.
The structure of the copper tube is extremely dense and impermeable. Harmful substances such as grease, bacteria, viruses, oxygen and ultraviolet rays cannot pass through it and pollute water quality.
In addition, the copper pipe does not contain chemical additives, and it will not burn and release toxic gases to suffocate people. The recycling of copper is beneficial to environmental protection and is a sustainable green building material.
Strong connection of copper pipe
There are many kinds of pipes on the market, but most of the interface fittings are made of copper. Even if some pipe parts can not use copper fittings, it still needs a copper fitting at the place where it connects with the faucet. However, if the copper pipe fittings are connected to other pipes, due to the different materials of the pipes and fittings, the physical and mechanical properties of thermal expansion and contraction are very different, and the firmness of the connection will naturally be subject to additional challenges. Therefore, the firmness of the connection between the copper pipe and the copper fittings will be greatly enhanced.
wholesome
Copper water pipes are good for health. Copper water pipes save water, prevent pollution and kill bacteria. When choosing or decorating a house, few people bother with the water supply pipes of the house. In fact, the material of the water supply pipe will greatly affect people's health.
In the past, galvanized steel pipes were often used for water supply in residential buildings in our country. Not only are they helpless against Escherichia coli and pneumonia bacteria that are easy to breed in water, but also because they are easily corroded by the atmosphere, soil and water, they will also cause secondary pollution to residential water. The copper water pipe has a strong ability to sterilize and disinfect. A biological survey showed that Escherichia coli in the water supply will not continue to multiply 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 is a small amount of copper ions dissolved in water in copper pipes, and copper ions have a strong bactericidal ability. For example, putting a small amount of copper in water can kill molluscs such as slugs, snails, and snails that breed in the water.

With the separation of traces of copper ions in the copper tube, the water containing copper ions can supplement the human body's demand for copper elements. Copper is one of the indispensable metal elements for human health. The latest research also shows that if the copper content in the nutritional structure of the meal is less than 1 mg/day, it is not suitable for adults. People already know that vegetables, fruits, grains, seafood, etc. can supplement the copper element in the human body, but experts remind that drinking water is also a way to absorb copper, because drinking water is almost a daily necessary behavior for people. But in most areas, the copper content in drinking water is not enough to provide the body's daily copper intake, and the use of copper pipes can at least minimize this deficiency. For a long time, people have invented some copper-containing medicaments to supplement the copper element in the human body. But instead of supplementing with medicine, it is better to really pay attention to the effects that are within reach. A healthy life needs to start from the source, and copper water pipes will silently "build" your strong physique.
