Finned tube

Banner

 

Finned tubes, also known as heat exchange tubes, are heat transfer components designed to enhance heat transfer efficiency by increasing surface area. They are suitable for high-temperature, high-pressure, and corrosive environments in industrial sectors such as boilers, power generation, and metallurgy.
 
Their core function is to reduce contact thermal resistance while offering corrosion resistance and wear resistance, making them commonly used in waste heat recovery and heat exchange equipment.

Operating continuously under conditions of high-temperature flue gas, high pressure, and corrosive atmospheres, finned tubes as heat exchange components must meet stringent performance requirements.
