L/LL/KL Finned Tube

Stainless Steel L/LL/KL Finned Tube Manufacturer in India, LL (Doulbe L) Finned Tubes, Steel L/LL/KL Finned Tube Exporter in Australia.

L/LL/KL finned tubes are specialized types of extended surface heat exchanger tubes that have specific fin arrangements. These finned tubes are designed to enhance heat transfer efficiency in various industrial applications where air-side heat exchange is critical.

L finned tubes have fins that are rectangular in shape and are aligned in a straight pattern along the length of the base tube. These fins are perpendicular to the tube’s surface, creating an “L” shape when viewed from the cross-section. L finned tubes are commonly used in applications where moderate heat transfer enhancement is required, such as in air coolers, air heaters, and some types of heat exchangers.

LL finned tubes, also known as “Double L” finned tubes, feature a configuration with two layers of rectangular fins perpendicularly aligned on the surface of the base tube. This double layer of fins increases the heat transfer surface area, resulting in higher heat transfer efficiency. LL finned tubes are utilized in applications where more substantial heat transfer enhancement is necessary, such as air-cooled heat exchangers used in power plants, refineries, and other high-temperature industrial processes.

KL finned tubes have fins that are trapezoidal in shape and are arranged in a straight pattern along the base tube’s surface. These fins are also called “Knurled” fins. The KL fin design provides high heat transfer efficiency due to the larger surface area compared to L finned tubes. They are well-suited for applications that require efficient cooling and heat dissipation, such as in air-cooled condensers and evaporators.

The choice between L/LL/KL finned tubes depends on the specific heat transfer requirements, temperature conditions, and environmental factors of the application. These finned tubes are commonly made from materials such as copper, aluminum, or stainless steel, depending on the corrosive and thermal properties required for the particular application.
