Lighter weight, good thermal conductivity, and high strength at low temperature. 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 strong and corrosion-resistant, and become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial buildings.
Copper pipe has many advantages in one: 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 general metal, and has certain frost heave and impact resistance. Therefore, it is in construction Once installed, the copper water pipe in the water supply system is safe and reliable to use, even without maintenance and maintenance.
The copper tube is hard in texture, not easy to corrode, and is resistant to high temperature and high pressure, 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, there will be problems such as yellowing of tap water and small water flow. There are also some materials whose strength 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.
