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.
