Introduction
H-finned Tube is a high-efficiency finned tube used in boilers, waste heat recovery, and high-temperature heat exchange systems. It adopts an "H"-shaped structure of carbon steel/alloy steel to achieve higher heat exchange efficiency and lower flue gas resistance.
Products Advantages
Higher Heat Exchange Efficiency
H-shaped parallel fins increase the effective heat exchange area (approximately +20%), reduce thermal resistance, and enable faster heat transfer.
Lower Flue Gas Resistance
The straight fin structure reduces turbulence, resulting in smoother flue gas flow and thus lower fan energy consumption.
High Temperature and Corrosion Resistance
The base tube and fins are made of heat-resistant alloy steel and use a uniform welded structure to ensure stable operation in high-temperature oxidizing environments.
Less Dust Accumulation
H-shaped flat fins have a small dust-receiving area, facilitating online soot blowing.
Manufacturing Process
Automated High-Frequency Welding: Continuous welds and uniform penetration depth improve fin bonding strength and prevent fin delamination at high temperatures.
CNC Fin Forming: Ensures consistent fin thickness and spacing, resulting in stable heat exchange performance across batches.
Base Tube Material Testing: Hardness, tensile, and pressure resistance tests are performed on materials such as SA213/SA192 to ensure reliable operation under high temperature and pressure.
Precise Assembly and Straightening: Fin alignment and spacing are corrected to ensure smooth flue gas flow and easy installation.
Appearance and Pressure Testing: Each fin is inspected for welds and appearance; water/gas pressure testing is available to ensure delivery quality.
Packaging and Transportation
Reinforced Packaging: Steel frames or wooden crates are used, along with spacers and moisture-proof film, to protect the fins from deformation and surface oxidation.
Transportation Methods: Sea, land, and air freight are supported; full container load (FCL)/less than container load (LCL) solutions are provided to ensure safe arrival of products and consistent installation dimensions.
