Aluminium Fins G Embedded for Boiler Heat Exchanger Superheater
The Aluminium Fins G Embedded for Boiler Heat Exchanger Superheater employs a G-shaped tube structure with aluminum fins, where the aluminum fins are fixed to the steel tube base tube using an embedding process.
- Tube Material:Stainless steel,Tube Diameter:15.88-50.80 mm,Wall Thickness:1.0-3.0 mm
- Fin Material:Aluminum,Fin Thickness:0.4-0.5 mm,Fin Pitch:2.1-6.0 mm,Fin Height:6.35-25.4 mm
The Aluminium Fins G Embedded for Boiler Heat Exchanger Superheater employs a G-type tube structure with aluminum fins, where the aluminum fins are fixed to the steel tube base tube using an embedding process. This design utilizes pre-machined spiral grooves on the base tube, embedding the aluminum strip within the grooves, and employing pre-tensioning force to ensure a good contact area between the fins and the base tube, thereby improving heat exchange efficiency.
The Aluminium Fins G Embedded for Boiler Heat Exchanger Superheater uses a copper or steel tube base tube with an embedded aluminum fin structure. A mechanical grooving process tightly embeds the aluminum strip into the spiral grooves of the steel tube, resulting in low contact thermal resistance and a pull-out force ≥70N.
Its design, with a fin spacing of 2.1-5mm and a fin height of <17mm, optimizes flue gas flow efficiency and withstands temperatures up to 400℃, making it suitable for petrochemical air coolers and boiler systems. This structure enhances heat transfer efficiency by increasing the heat dissipation area, and, combined with materials such as 20G boiler steel, can withstand high-temperature flue gas of 400-1200℃, significantly improving waste heat recovery.
This superheater exhibits high temperature resistance, with an allowable medium temperature up to 400℃, and strong resistance to thermal shock, making it suitable for high-temperature operating conditions.
Its manufacturing process emphasizes stability, with precise fin spacing control, secure embedding, and a pull-out force of no less than 70N, ensuring long-term operational reliability.
In boiler systems, this type of superheater is mainly used to increase steam temperature and enhance heat exchange, commonly found in equipment such as petrochemical air coolers. When using it, it is necessary to match the system pressure and temperature requirements to fully utilize its high-efficiency heat exchange advantages.

Aluminium Fins G Embedded for Boiler Heat Exchanger Superheater Appearance Dimension Inspection
Aluminium fins g embedded for boiler heat exchanger superheater appearance dimension inspection is one of the important links to ensure the quality and performance of fin tubes.
The inspection items mainly include fin height, fin spacing, fin thickness, base tube wall thickness and outer diameter, etc.
Datang Aluminium Fins G Embedded for Boiler Heat Exchanger Superheater Bending Processing
Bending of fin tubes is an important step in the production process of aluminium fins g embedded for boiler heat exchanger superheater. Bending is to bend the embedded fin tube material through specific mechanical equipment to form a suitable curvature to meet different usage requirements.
This step requires strict control of the bending angle and curvature to ensure the fit between the fin and the base tube and the heat dissipation effect.
Aluminium Fins G Embedded for Boiler Heat Exchanger Superheater Pull Off Test
G type embedded finned tube pull-off test is a test used to detect whether the fin tube will fall off when subjected to tension, mainly used to ensure the quality and reliability of the fin tube.
Datang’s this test is very important in the production process because the g type finned tubes will be subjected to various stresses during operation, such as temperature changes and pipe expansion, which may cause the fin to fall off, thereby affecting the performance and safety of the heat exchanger .
