Carbon steel and aluminum rolled finned tube
Finned Tube Overview
Finned tubes, designed to enhance heat exchange efficiency, typically increase the surface area (either external or internal) of the heat exchange tubes by adding fins, thereby improving the heat exchange efficiency. Such heat exchange tubes. As heat exchange elements, finned tubes operate under harsh conditions of high-temperature flue gas, such as in boiler heat exchangers, where they are exposed to high temperatures, pressures, and corrosive atmospheres. This necessitates that finned tubes possess high performance specifications.
1. Corrosion resistance
2. Abrasion resistance
3. Low contact thermal resistance
4. High Stability
5. Dust Resistance Ability
Finned tube classification
The types of finned tubes are numerous and new varieties are continually emerging. Finned tubes can generally be categorized into the following aspects based on their application scenarios:
Categorized by processing technology: 1. Strip Tube (Sleeve Tube); 2. Tension Wound Finned Tube; 3. Inserted Fin Tube; 4. Seamless Finned Tube; 5. Cast Finned Tube; 6. Welded Finned Tube, which includes: High-Frequency Welded Finned Tube, Submerged Arc Welded Finned Tube, etc.
Categorized by fin shape: 1. Square, rectangular, and circular finned tubes; 2. Spiral finned tubes; 3. Wavy finned tubes; 4. Toothed finned tubes; 5. Pin finned tubes; 6. Vertical finned tubes; 7. Solid plate finned tubes (plate fins) etc.
Material Categorization: 1. Copper, Aluminum, Copper/Aluminum finned tubes; 2. Carbon steel, Stainless steel, Carbon steel/Stainless steel finned tubes; 3. Cast iron (cast steel) finned tubes, etc.
Categorized by application: Air conditioning finned tubes; Air-cooling finned tubes; Boiler finned tubes for water walls, economizers, and air preheaters; Finned tubes for various kilns and industrial furnaces for waste heat recovery; and other special-purpose finned tubes, etc.
Finned tube advantages
1. High Efficiency and Energy Saving: Its heat exchange coefficient ranges from 3000 to 4500 kcal/m²·°C·h, which is 3 to 5 times more efficient than shell-and-tube heat exchangers.
2. Compact Structure: Plate heat exchangers have tightly packed plates, requiring less floor space and overall volume compared to other types of heat exchangers. A plate heat exchanger with the same heat transfer capacity as a shell-and-tube exchanger only occupies 1/5 of the area.
3. Easy to Clean and Dismantle: The plate heat exchanger clamps the plate sections together with clamping bolts, making it convenient for disassembly. It can be opened up for cleaning at any time. Additionally, due to its smooth surface and high turbulence, it is less prone to scaling.
4. Long Service Life: Plate heat exchangers are made of stainless steel or titanium alloy plates, resistant to various corrosive media. Gaskets are replaceable and can be easily assembled, disassembled, and inspected.
5. Versatile: Plate heat exchanger plates are individual components, allowing for the addition or reduction of circuits as required, with various configurations; suitable for different process requirements.
6. Non-interference in fluid flow; the plate heat exchanger features a sealed groove with a drainage channel, ensuring that various media do not mix. In the event of a leak, the medium always discharges outward.
