ASTM A312 TP304 Stainless Steel Corrugated Tube Spiral Tube for Heat Transfer
Corrugated tubes are designed with ridges or corrugations on their surface, which enhances heat transfer efficiency. These tubes are commonly used in heat exchangers and other thermal management systems where efficient heat transfer is crucial. The corrugations increase the turbulence of the fluid flowing inside the tube, leading to improved heat transfer coefficients.
The enhanced surface area due to the corrugations allows for better heat transfer between the fluid inside the tube and the surrounding environment. This makes corrugated tubes particularly useful in applications where heat exchange efficiency is a priority, such as in industrial processes, HVAC systems, and renewable energy technologies.

The advantages of corrugated fin tubes include
Enhanced Heat Transfer: The corrugated structure increases the surface area of the tube, allowing for better heat transfer efficiency. This results in improved performance of the heat exchanger.
Flexibility: The corrugated design makes the tubing more flexible, which can be beneficial in installations where some degree of movement or vibration is expected.
Resistance to Thermal Stress: Corrugated tubing is better able to withstand thermal stress and thermal expansion compared to traditional smooth tubes, making them more durable in high-temperature applications.
Corrosion Resistance: Stainless steel is known for its excellent corrosion resistance properties, making it an ideal material for heat exchangers handling corrosive fluids.
Reduced Fouling: The corrugated surface can help reduce fouling or deposit build-up on the tube, ensuring better long-term performance and ease of maintenance.
