Low Fin Tubes / Integral Fin Tubes Copper Nickel ASTM B111 C70600 For Condensers
Low Fin Tubes
The Low Fin Tubes/Integral Fin Tubes are increasingly being used in various fluid heat Eexchangers. They are specialized heat exchangers designed to enhance heat transfer efficiency while maintaining a compact structure. They feature low-profile fins that are attached to the outer surface of the tube, increasing the surface area available for heat exchange.
It is suitable for the shell side medium is relatively clean, no corrosion, no scaling, can use low thread finned tube as heat exchange element to form low thread finned tube high efficiency heat exchanger.
Design Features
Fins:The fins are typically spaced apart and have a low height, which minimizes flow resistance while still providing significant surface area for heat transfer.
Material:Typically constructed from materials such as carbon steel, stainless steel, alloy or copper, providing durability and resistance to corrosion.
