Copper tube, also known as red copper tube, is a seamless tube that is pressed and drawn.
Copper pipes are lighter in weight, have good thermal conductivity, and have high strength at low temperatures. Often used in the manufacture of heat exchange equipment (such as condensers, etc.). It is also used to assemble cryogenic pipelines in oxygen production equipment. Copper pipes with small diameters are often used to transport pressured liquids (such as lubrication systems, oil pressure systems, etc.) and pressure measuring tubes for instruments.
Copper pipes are the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial buildings.
1. Because the copper pipe is easy to process and connect, it can save material and total cost during installation, has good stability and reliability, and can save maintenance.
2. Copper is light. For twisted threaded pipes of the same inner diameter, copper pipes do not require the thickness of ferrous metal. When installed, the transportation cost of copper pipes is smaller, maintenance is easier, and it takes up less space.

3. Copper can change its shape. Because copper tubes can be bent and deformed, they can often be made into elbows and joints. The smooth bend allows copper tubes 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 pipes are resistant to high temperatures and can be used in a variety of environments. Compared with this, the shortcomings of many other pipes are obvious. For example, the galvanized steel pipes used in residential buildings in the past are very easy to rust. If they are not used for a long time, the tap water will turn yellow and the water flow will become small. In addition, the strength of some materials will decrease rapidly at high temperatures, which may cause unsafe hazards 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 negligible for copper pipes. Archaeologists discovered a copper water pipe 4,500 years ago in the Egyptian pyramids, which is still in use today.
Copper pipes (also known as red copper pipes) are often used in water pipes, heating and cooling pipes, and can be used in different environments. Copper pipes combine the advantages of metal and non-metal pipes. They are the best connection pipes in the cold and hot water system. Copper pipes are fire-resistant and heat-resistant, and can maintain their shape and strength at high temperatures without aging.
The pressure resistance of copper pipes is several times or even dozens of times that of plastic pipes and aluminum-plastic pipes, and it can withstand the highest water pressure in today’s buildings. In a hot water environment, with the extension of the service life, the pressure-bearing capacity of plastic pipes decreases significantly, while the mechanical properties of copper pipes remain unchanged in all thermal temperature ranges, so their pressure-resistant capacity will not decrease, nor There will be aging.
The linear expansion coefficient of the copper pipe is very small, which is 1/10 of that of the plastic pipe, and it will not cause stress fatigue cracking due to excessive thermal expansion and contraction.
