DINKONDA GLOBAL Power Plants Special Exhaust Gas Heat Recovery Heat Exchange

Product Specification

DINKONDA GLOBAL Power Plants Special Exhaust Gas Heat Recovery Heat Exchange Device, Pressure ≤ 2.5MPa, Diameter 20-48mm, Stainless Steel Spiral Finned Heat Exchange Tube

Product Overview
This 304 stainless steel finned tube adopts the winding process, and the base tube is a seamless stainless steel pipe. The stainless steel strip is continuously wound and welded to the outer surface of the base tube, greatly increasing the heat exchange surface area and enhancing the heat exchange efficiency between air and the medium inside the tube. It is the core heat exchange element of hot air heat exchangers, air coolers, radiators, drying equipment, and boiler waste heat recovery devices. Produced by DINKONDA GLOBAL, it is widely used in industrial heating, cooling, waste heat recovery, HVAC drying and other working conditions. It can adapt to various in pipe heat exchange media such as steam, thermal oil, hot water, etc.

Structural Composition
1. Base pipe (heat exchange base pipe): 304 stainless steel seamless steel pipe, with steam, hot water, heat transfer oil and other media circulating inside the pipe, bearing the pressure and temperature of the media.

2. Stainless steel fins: 304 stainless steel thin steel strip, spiral tightly wrapped around the outer wall of the base pipe, increasing the heat dissipation and exchange area. The fins are firmly combined with the base pipe, reducing the contact thermal resistance.

3. End locking welding position: Spot welding is used to lock the fins at both ends to prevent loosening, movement, and detachment caused by operational vibration, ensuring long-term operational stability.

Product Features
1. High heat transfer efficiency: With a wound structure and uniform fin density, the heat transfer area is greatly expanded, and the heat transfer capacity is several times higher than that of a light tube, resulting in excellent heat transfer performance.

2. Material corrosion resistance: The overall 304 stainless steel material is resistant to oxidation and water vapor corrosion, suitable for humid, slightly corrosive flue gas, and air conditions, and is not easy to rust.

3. High bonding strength: The rear end of the steel strip is welded and fixed, and the fins are closely attached to the base tube, with low contact thermal resistance, vibration resistance, and less likely to detach.

4. Good high temperature resistance: It can adapt to high temperature steam and heat transfer oil working conditions, with a wide temperature range and matching thermal expansion performance. It is not easy to deform or loosen under high temperature working conditions.

5. Reasonable fluid resistance: Spiral arrangement of fins, moderate air flow resistance on the air side, suitable for fan blowing/induced draft heat exchange systems.

6. Flexible customization of specifications: The base tube diameter, fin height, fin spacing, effective heat transfer length, and total length can be customized according to the heat exchanger assembly drawing.
