Heat Exchanger Stainless Steel H Shaped Finned Tube A312 TP304L TP316L
The H-shaped fin tube is a specialized heat exchange component designed to enhance thermal efficiency in various industrial applications. Its unique H-shaped fin configuration (resembling the letter "H" when viewed in cross-section) increases the heat transfer surface area while improving structural stability.
What is the Characteristic of H-shaped fin tube?
- The fin is divided into two symmetrical half pieces. The tube wall is pressed down from both sides, and resistance welding is used to weld on the pipe wall with a certain gap left in the middle;
- Two circular tubes can share a group of fins, called double tube H-shaped fins, or a single tube H-shaped fin can be placed in the middle;
- The heat exchanger composed of H-type finned tubes is closely arranged and the tube bundles are arranged in order;
- The fins are parallel and independent of each other, and there is no influence of helix angle, so it is easy to remove ash.
Applications of H-Shaped Fin Tubes
1. Waste Heat Recovery Systems
- Used in boilers, economizers, and air preheaters to recover heat from flue gases, improving energy efficiency in power plants and industrial processes.
2. Power Plant Boilers
- Enhances heat transfer in coal-fired, gas-fired, and biomass boilers, reducing fuel consumption and emissions.
3. Chemical & Petrochemical Industries
- Employed in **heat exchangers, reformers, and reactors** where high-temperature and corrosive environments demand durable heat transfer surfaces.
4. Steel & Metallurgical Plants
- Used in recuperators and heat exchangers to recover waste heat from furnaces and exhaust gases.
5. Marine & Offshore Applications
- Suitable for exhaust gas boilers in ships, where compact and efficient heat transfer is critical.
6. HVAC & Refrigeration
- Occasionally used in large-scale heat recovery ventilators (HRVs) and industrial chillers.
Advantages of H-Shaped Fin Tubes
- High Heat Transfer Efficiency – The H-shape creates turbulence, improving convective heat transfer.
- Reduced Fouling & Soot Deposition – The design minimizes ash and particulate buildup, common in flue gas applications.
- Structural Strength – More rigid than spiral or plain fin tubes, reducing vibration and wear.
- Compact Design – Allows higher heat exchange in a smaller footprint compared to smooth tubes.
- Corrosion Resistance – Often made from stainless steel or corrosion-resistant alloys for harsh environments.
H-shaped fin tubes are ideal for high-temperature, high-fouling, and high-corrosion environments, making them a preferred choice in power generation, waste heat recovery, and heavy industries. Their design balances thermal performance, durability, and maintenance efficiency.
