Product Specification

Corrugated Tube/Bamboo Tube ASTM A312 TP310S For Heat Exchanger and Air Cooler

What is Corrugated Finned Tube?

Corrugated finned tubes are heat exchanger components used in various industrial applications, including power generation, petrochemical, and HVAC systems. The tubes are made of carbon steel, stainless steel, and other alloys, with a corrugated outer surface that increases the heat transfer efficiency of the tube by increasing the available surface area. The fins are continuous and formed from the same metal as the tube. The corrugation creates a turbulent flow, enhancing heat transfer. The tubes are used for air-cooled heat exchangers, compact heat exchangers, and condensers.

What's the advantage of Corrugated finned tubes?

There are several advantages of using corrugated finned tubes in heat exchangers:

1. Increased Heat Transfer: The corrugated fins on the tube increase the surface area, which improves the heat transfer efficiency of the tube. This means that heat can be transferred more efficiently, resulting in faster and more effective cooling or heating.

2. Reduced Fouling: The corrugated surface can prevent fouling on the finned tube, which occurs when contaminants accumulate on the surface. This can prolong the life of the heat exchanger and reduce maintenance costs.

3. Compact Design: The design of corrugated finned tubes allows for a more compact heat exchanger, which can save space and reduce installation costs.

4. Enhanced Durability: Corrugated finned tubes are more resistant to mechanical stress and thermal cycling than smooth tubes. This means that they are less likely to deform or fail over time.

5. Versatility: Corrugated finned tubes can be made of various materials, such as stainless steel, carbon steel, and copper. This makes them suitable for a wide range of applications and environments, including corrosive and high-temperature environments.
