Embedded Aluminum Extruded Tubing for boilers is a type of heat-exchange tube that is used in boilers for efficient heat transfer. This tube consists of a base tube (usually made of steel) with aluminum fins that are extruded and then embedded onto the external surface of the base tube.

The extrusion process involves squeezing the aluminum through a die, which creates fins with specific dimensions and profiles. These fins are then tightly bonded to the base tube through mechanical interlocking or by using a high-temperature soldering process.

The embedded fin design increases the surface area of the tube, allowing for improved heat transfer between the hot flue gases and the fluid inside the tube (usually water or steam). The increased surface area increases the efficiency of heat exchange, resulting in higher thermal efficiency and reduced energy consumption of the boiler.

Embedded Extruded Fin Tubes are commonly used in industrial boilers, power plants, and other applications where efficient heat transfer is crucial. They are known for their high thermal conductivity, excellent resistance to corrosion and atmospheric weathering, and their ability to withstand high temperatures and pressures.
