Corrosion-resistant and high-temperature resistant copper tube for pressurized liquids delivery

Copper tube is also called red copper tube. A kind of non-ferrous metal pipe, which is pressed and drawn seamless pipe. Copper pipe has the characteristics of good electrical conductivity and thermal conductivity. It is the main material for electrical and heat-dissipating accessories of electronic products. It has become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial buildings. Copper pipes 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 and shape.

Copper pipes are lighter in weight, have good thermal conductivity, and have high strength at low temperatures. Commonly 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 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, 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.
