What are extruded finned tubes for drying rooms?
Extruded finned tubes for drying rooms are high-efficiency heat dissipation devices. Through a precision extrusion process, fins are combined with a base tube, improving heat exchange efficiency and making them suitable for various drying scenarios.
Structural Features of Extruded Finned Tubes for Drying Rooms
Material Selection: Commonly used are steel-aluminum composite finned tubes or stainless steel finned tubes. Steel-aluminum composite tubes offer superior heat exchange performance and are suitable for drying sensitive materials such as food.
Process Advantages: The extrusion process ensures a tight bond between the fins and the base tube, increasing the heat dissipation area and shortening the heating time.
Customized Design: The frame size, number of heat dissipation tubes, and arrangement can be adjusted to adapt to different drying room space requirements.
How to Choose the Right Finned Tubes for Drying Rooms?
1. Selection Based on Drying Room Area
Small drying rooms (≤300㎡): Choose finned tubes with lower prices and moderate temperature control range.
Medium drying rooms (300-5000㎡): Balance price and performance.
Large drying rooms (>5000㎡): Prioritize customized services.
2. Selection Based on Material Corrosion Resistance
Carbon steel: Low price, suitable for non-corrosive environments, such as Cangzhou Datang Pipe Industry’s high-frequency welded carbon steel finned tubes.
Stainless steel 304/316L: Strong corrosion resistance, suitable for chemical, food processing, and other applications.
Steel-aluminum composite material: Combines thermal conductivity and corrosion resistance, such as Datang rolled and extruded bimetallic finned tubes.
3. Process Type Comparison
High-frequency welding: Low cost, high heat dissipation efficiency.
Extrusion molding: Complex process but durable.

Extruded Finned Tubes for Drying Rooms Appearance Dimension Inspection
Extruded finned tubes for drying rooms 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.
Extruded Finned Tubes for Drying Rooms Bending Processing
Bending of fin tubes is an important step in the production process of extruded finned tubes for drying rooms. Bending is to bend the astm a179 tube aluminum fin composited extruded finned tubes 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.
Extruded Finned Tubes for Drying Rooms Pull Off Test
Extruded finned tubes for drying rooms 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 extruded finned tubes for drying rooms 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 .
