Due to the excellent high-temperature and high-pressure characteristics of 16Mo3 alloy steel, it is suitable for manufacturing finned tubes used in heat exchangers and boilers. Common types of fins include:

1. Longitudinal Fins: Suitable for applications where increased heat dissipation surface area is needed.

2. Transverse Fins: Wrapped around the outside of the tube, used to enhance heat dissipation.

3. Helical Fins: Spiral-shaped fins providing higher heat transfer efficiency.

 

 

1. High-Temperature Resistance: 16Mo3 alloy steel maintains good strength and stability at high temperatures.

2. High-Pressure Capability: Suitable for equipment operating under high-pressure conditions, such as boilers.

3. Good Weldability: 16Mo3 can be processed and joined using common welding methods.

4. Oxidation and Corrosion Resistance: Alloy composition enhances resistance to oxidation and corrosion.

 

 

Seamless alloy steel 16Mo3 tubes are commonly used in the manufacturing of high-temperature and high-pressure equipment, especially finned tubes for heat exchangers and boilers. These applications are found in various industries, including:
