Material of seamless heat exchanger tube

Heat exchange tubes are integral components of heat exchangers, positioned inside the cylinder to facilitate the heat exchange between two media. They are characterized by high thermal conductivity and excellent isothermal properties. These tubes efficiently transfer heat energy from one point to another with minimal heat loss, earning them the title of heat transfer superconductors. Their thermal conductivity can be thousands of times that of copper.

Applications and Materials of Heat Exchange Tubes

Heat exchange tubes are essential in various systems, including hot and cold water systems, air conditioning systems, steam transportation, and industrial cooling systems. The choice of material for these tubes varies depending on the application requirements, and the most common materials include:

1. Copper Tubes

Copper tubes are the most widely used material for heat exchange tubes due to their excellent thermal conductivity. They are ideal for high-efficiency heat exchangers, offering resistance to corrosion, long service life, high temperature, and high-pressure resistance. Copper tubes are economical and practical, making them suitable for use in heating, refrigeration, air conditioning, electricity, and chemical industries.

2. Steel Pipes

Steel pipes are another common material for heat exchange tubes. They are relatively inexpensive, easy to process and install, and possess high strength and pressure resistance. Steel pipes can withstand high temperatures and pressures, making them suitable for high-temperature and high-pressure applications. They are available in two main types: seamless steel pipes and welded steel pipes.

3. Stainless Steel Pipes

Stainless steel pipes are known for their strength, wear resistance, and rigidity, particularly suitable for high-temperature and high-pressure environments. They offer excellent corrosion resistance and high strength, making them ideal for manufacturing high-temperature and corrosion-resistant heat exchangers. Stainless steel pipes have a long service life and are widely used in industrial, chemical, and aerospace applications. However, their high cost necessitates careful evaluation based on actual needs.

4. Aluminum-Plastic Composite Pipes

Aluminum-plastic composite pipes consist of an inner aluminum layer tightly bonded to an outer plastic layer through a special manufacturing process. These pipes are lightweight and cost-effective, making them popular in construction, water heating, and heating applications.

In summary, the selection of heat exchange tube material depends on specific application requirements, balancing factors such as thermal conductivity, corrosion resistance, strength, and cost.
