First, excellent thermal conductivity
The thermal conductivity of copper reaches 390W/(m-K), far exceeding ordinary steel by more than 4 times. This characteristic makes the heat can be quickly conducted in the copper pipe wall, significantly improve the transient response of the heat exchanger. Experimental data show that the heat transfer efficiency of copper tube heat exchanger under the same working conditions than stainless steel tube 30% -40% higher.
Second, the long-lasting chemical stability
In the acid and alkali salt corrosion environment, the surface of the copper tube will spontaneously form a dense oxidized protective layer. This passivation phenomenon makes it in the pH value of 2-12 medium can still maintain structural integrity, especially suitable for chemical industry, refrigeration and other harsh conditions. Long-term tracking studies show that the service life of high-quality copper pipe in seawater environment can reach more than 15 years.
Third, excellent mechanical reliability
Copper tubes have both ductility and strength, and their tensile strength can reach 200-300MPa. Copper tube systems connected by hard brazing can withstand working pressure of more than 2.5MPa, and there is no weld cracking after more than 1,000 times of thermal cycle test. The material memory effect enables the copper pipe to return to its original state after deformation, significantly reducing operation and maintenance costs.
IV. Balancing Economy and Sustainability
Although the unit price of copper is higher, its comprehensive life cycle cost is lower than alternative materials. The 100% recyclable nature of copper pipe meets the requirements of green manufacturing, and currently more than 85% of the world's liquid heat exchangers still use copper pipe solutions.
Current copper tube manufacturing technology has developed improved varieties such as internally threaded tubes and nano-coated tubes, further expanding the boundaries of its application in the field of efficient heat exchange. Materials scientists predict that copper tubing will remain the dominant heat exchanger tubing market for the next decade.
