What types of extruded fin tubes are available?
Extruded finned tubes are key components in many industries, providing efficient heat transfer in applications ranging from power plants to HVAC systems. These specialised tubes are designed to improve thermal performance by increasing heat exchange surface area. Extruded finned tubes stand out due to their durability, corrosion resistance, and superior thermal conductivity.
High Frequency Welded Extruded Fin Tubes
High frequency welded extruded finned tubes are manufactured using a welding process that ensures a strong bond between the fins and the base tube. The welding process uses a high-frequency electric current to generate heat and fuse materials together. This type of finned tube is commonly used in industries that require extra durability and resistance to high pressure conditions, such as petrochemical plants and power generation facilities.
Features
Durability High strength bond between fin and tube
Corrosion resistance Suitable for environments where corrosive materials are exposed.
Thermal efficiency High heat transfer rate due to optimal material integration
Applications
Heat exchangers in refineries
Throttles in power plants
HVAC systems with high pressure requirements
L-Type Extruded Finned Tubes
L-shaped extruded finned tubes feature L-shaped fins mechanically wrapped around the base tube. These fins provide excellent heat transfer while protecting the base tube from thermal stresses and corrosive environments, and the L-shaped fin design ensures that the fins remain securely attached to the base tube even under extreme thermal cycling conditions.
Features
Enhanced stability L-shaped fins ensure a strong connection
Cost effective Manufactured using simpler technology at an affordable price
Thermal protection Reduced thermal expansion and stress on the base tube
Applications
Air cooling heat exchangers in chemical plants
Industrial dryers
Condensers in refrigeration systems
G-fin extruded tubes
G-fin extruded tubes get their name from the grooves cut into the base tube. These grooves hold the fins in place for a tight fit, thus enhancing thermal conductivity and mechanical stability. This design is particularly suitable for high temperature applications where conventional bonding methods may fail.
Features
High temperature performance Ideal for heat exchangers exposed to extreme temperatures
Mechanical bonding Prevents fins from loosening during heavy use
Customisable design Suitable for a wide range of tubes and sizes
Applications
Boilers and preheaters
Heat recovery systems
Marine industry applications such as desalination plants
Embedded Finned Tubes
Embedded finned tubes are made by inserting fins into pre-machined grooves in the base tube. This method provides a highly secure fit, making these tubes ideal for applications requiring high thermal conductivity and vibration resistance.
Features
Vibration resistant Ideal for dynamic environments with constant motion
Corrosion resistant Ideal for use in salt water or chemically aggressive environments.
Highly efficient heat exchange Improved thermal conductivity due to direct material contact.
Applications
Marine heat exchangers
Offshore oil and gas platforms
Automotive and aerospace cooling systems
Extruded aluminium finned tubes
Extruded aluminium finned tubes are made by extruding aluminium over a base tube, creating a seamless connection between the fin material and the core material Aluminium's light weight and excellent thermal properties make these finned tubes a favourite in industries where energy efficiency is important.
Features
Lightweight construction Easier to handle and install
Excellent corrosion resistance Ideal for environments exposed to moisture and air.
Aesthetics Commonly used in applications where visual appeal and functionality are required.
Applications
HVAC systems in commercial buildings
Air cooling condensers in industrial applications
