Product Introduction: High-Efficiency H Finned Tubes for Heat Exchangers

Heat exchangers are critical components in various industrial applications, playing a significant role in energy efficiency and thermal management. At the forefront of innovative design and manufacturing, we present our advanced H fin tube modules, which optimize the performance of heat exchangers while minimizing heat transfer losses and pressure drops. Our extensive expertise in designing economizers, heat exchangers, and tailored cleaning systems ensures that we meet the specific requirements of our customers across multiple sectors.

Overview of H Finned Tubes

The H fin tube, commonly referred to as a square fin tube, features two prominent types: the single H fin tube and the twin H fin tube, also known as rectangular fin tubes. This design is characterized by steel circular fins welded onto a base tube, forming fins that resemble the letter "H". This unique shape significantly increases the surface area available for heat exchange, consequently enhancing the efficiency of air heating applications.

Due to their rectangular design, H fin tubes provide a substantial surface area compared to their spiral finned tube counterparts, resulting in reduced overall equipment size and more effective heat transfer capabilities. The H fin tubes are primarily utilized in various boiler applications, including utility and industrial boilers, as well as marine power contexts, particularly in the tail heat exchanger components.

Technical Specifications

The operational performance of H fin tubes is impressive:

• Maximum Working Temperature: 300 °C
• Atmospheric Corrosion Resistance: Excellent
• Mechanical Resistance: Robust
• Fin Materials: Options include copper, aluminum, carbon steel, and stainless steel.
• Base Tube Materials: A diverse selection includes carbon steel (such as A179, A192, A210) and various grades of stainless steel (such as A269/A213 T5, T11, T22, 304, 316).

In addition to standard designs, we offer customization options for both single pipe square finned tubes and twin pipe rectangular finned tubes, making them ideal for handling dust-laden exhaust gases typical in coal and oil-fired systems or waste incinerators.

Advanced Applications: Oval Finned Tubes

Our product line also includes oval fin tubes, which feature a design that maximizes thermal transfer. These tubes can operate at the following specifications:

• Applied Temperature: Up to 850 °C (1593 °F)
• Common Applications: Suitable for air-cooled and oil-cooled heat exchangers, condensers, and heaters found in oil refineries, petrochemical industries, offshore operations, and power plants.

Types of H Finned Tubes

1. H Finned Tube Economizers: These advanced heat exchangers utilize rectangular fins welded onto one or two steel base tubes, enhancing the heat exchange surface area efficiently.

2. Twin H Finned Tube (HH or Double H): Composed of two symmetrical halves, these tubes utilize resistance welding to manufacture robust and efficient designs that allow for longer tube rows.

3. Single H Finned Tube: Characterized by a single round tube at the center, this type features fins welded on two sides, maximizing efficiency without compromising structural integrity.
