Copper tube is also called purple copper tube. One kind of non-ferrous metal pipe is pressed and drawn seamless pipe. Copper pipes have strong and corrosion-resistant characteristics, and have become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial houses. Copper pipe is the best water supply pipe.

Chinese Name: copper pipe

Foreign name: copy tubing; copper pipe

Another name: copper tube

Category: one kind of non-ferrous metal pipe

Copper tube is light in weight, good in thermal conductivity and high in low temperature strength. It is often used to manufacture heat exchange equipment (such as condenser). It is also used for assembling low-temperature pipelines in oxygen production equipment. Copper pipes with small diameters are often used to transport liquids under pressure (such as lubrication systems, oil pressure systems, etc.) and pressure measuring pipes used as instruments.

Copper pipes have strong and corrosion-resistant characteristics, and have become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial houses.

Because 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.

Copper is light. For twisted thread pipes with the same inner diameter, the copper pipe does not need the thickness of ferrous metal. When installed, the transportation cost of the copper pipe is smaller, the maintenance is easier, and the occupied space is smaller.

Copper can change its shape. Because the copper pipe can be bent and deformed, it can often be made into elbows and joints. Smooth bending allows the copper pipe to be bent at any angle. Copper is easy to connect. Copper is safe. No leakage, no combustion, no toxic gas, corrosion resistance.

Copper pipe is hard, not easy to corrode, and resistant to high temperature and high pressure. It can be used in a variety of environments. Compared with this, the disadvantages of many other pipes are obvious. For example, the galvanized steel pipes used in the past are very easy to rust, and the running water will turn yellow and the water flow will become small if they are used for a short time. The strength of other materials will rapidly decrease at high temperature, which may cause unsafe risks when used in hot water pipes. The melting point of copper is as high as 1083 degrees Celsius, and the temperature of the hot water system is insignificant to the copper pipes. Archaeologists found a copper water pipe 4500 years ago in the pyramids of Egypt, which can still be used today.

Copper pipes (also known as red copper pipes) are commonly used in water pipes, heating and cooling pipes. As installation pipes, they have the advantages of hard texture, not easy to corrode, high temperature resistance and high pressure resistance, and can be used in different environments. Copper pipe combines the advantages of metal and non-metal pipes. It is the best connecting pipe in the cold and hot water system. The copper pipe is fire-resistant and heat-resistant. It can still maintain its shape and strength under high temperature, and there will be no aging phenomenon.

The pressure resistance of copper pipe is several times or even dozens of times that of plastic pipe and aluminum-plastic pipe. It can withstand the highest water pressure in today's buildings. Under the hot water environment, with the extension of service life, the pressure bearing capacity of plastic pipes will decrease significantly, while the mechanical properties of copper pipes will remain unchanged in all thermal temperature ranges, so the pressure bearing capacity will not decrease and aging will not occur.

The linear expansion coefficient of copper pipe is very small, which is 1 / 10 of that of plastic pipe. It will not cause stress fatigue fracture due to excessive thermal expansion and cold contraction. The strength of the steel pipe is greater, and the outer diameter is smaller under the requirement of ensuring the effective inner diameter, which is more suitable for concealed burial.

Copper pipe has a long history of application in buildings. It is recognized as a pipe with excellent performance that has been fully tested for more than 100 years and practical experience. As a water supply pipe, gas pipe and heating pipe, it has unique charm.

Copper pipe is widely used in developed countries in Europe and America. In China, especially in Shanghai, a large number of copper pipes were used in buildings in the early period of liberation. In the early days of the founding of the people's Republic of China, people's living standards were low and their requirements for quality of life were not high. At the same time, due to the needs of national defense construction, copper was less used in residential buildings as a strategic material. After the reform and opening up, the regulations restricting the use of copper materials were abolished, and the code for design of building water supply and drainage also specified the application of copper pipes in the articles on pipe selection.

With the rapid growth of China's economy and the rapid improvement of people's living conditions, people have higher requirements for the quality of life. The concept of "treasure in famous mountains and copper in famous houses" has begun to rise quietly.

Copper pipe combines many advantages: it is strong and has the high strength of general metal; At the same time, it is easier to bend, twist, crack and break than ordinary metals, and has certain frost expansion and impact resistance. Therefore, once installed, the copper water pipe in the water supply system in the building is safe and reliable to use, even without maintenance and repair.
