High Frequency Welding Serrated Fin Tube ASTM A192 CS Fin For Furnace

Product Specification

High Frequency Welding Fin Tube Serrated ASTM A192 CS Fin For Furnace

It is a high-efficiency component designed to enhance thermal performance in industrial heating systems. Here's a detailed overview:

1. Material Specifications

Base Tube: ASTM A192 Carbon Steel
-Standard: ASTM A192 is a specification for seamless carbon steel boiler tubes designed for high-pressure service.
-Material Properties:
-High Strength: Excellent mechanical properties to withstand high pressures and temperatures.
-Thermal Conductivity: Ensures efficient heat transfer, a critical requirement for furnace operations.
-Corrosion Resistance: Provides moderate resistance to scaling and oxidation in high-temperature environments.

Fins: Serrated Carbon Steel (CS)
-Material: The fins are made from carbon steel for compatibility with the base tube in terms of thermal expansion and strength.
-Serration:
The fins are designed with serrations (notched edges) to promote turbulence in the medium (air, gas, or fluid) flowing across the tube.
Serrated fins enhance heat transfer efficiency by disrupting the boundary layer, which improves the thermal exchange rate.
 

2. High-Frequency Welding (HFW)
Process:
Fins are welded to the base tube using high-frequency electric resistance welding.
This process creates a strong metallurgical bond that ensures long-term durability and consistent performance.
Advantages:
-Strong Bonding: Ensures the fins are securely attached to the tube, even under thermal cycling and vibrations.
-Thermal Consistency: Minimizes heat resistance between the fins and the tube, ensuring efficient heat transfer.
-Durability: The welded connection withstands extreme furnace conditions.
 

3. Furnace Application
Purpose of Fin Tubes in Furnaces:

Fin tubes are critical for increasing the heat transfer surface area, allowing furnaces to operate more efficiently.
Serrated fins further improve performance by inducing turbulence, reducing thermal resistance in the surrounding medium.
