DINKONDA GLOBAL Power Plants Special Shell And Tube Heat Exchanger For Waste Heat Recovery Equipment, Carbon Steel/stainless Steel Spiral Heat Exchanger Finned Tubes

Product Overview
Spiral finned tube is the core heat exchange element of shell and tube heat exchangers, air heaters, radiators, and waste heat recovery equipment. It adopts the steel strip spiral winding process to tightly wrap the finned steel strip around the outer wall of the base tube, greatly expanding the gas side heat transfer area and strengthening the heat transfer between the medium inside the tube and the gas and flue gas outside the tube. Widely used in steam, hot water, and thermal oil heat exchange conditions, suitable for various air medium heat exchange equipment such as industrial drying, HVAC heating, flue gas waste heat recovery, and chemical cooling.

Structural Composition
1. Heat exchange base tube: As a medium circulation carrier, carbon steel, stainless steel, and alloy steel pipes can be selected to withstand system pressure and medium temperature.

2. Spiral finned steel strip: The steel strip is continuously spiral wrapped around the outer surface of the base tube to form continuous spiral heat dissipation fins, increasing the heat transfer surface area.

3. End welding locking parts: The fins are fixed by spot welding at both ends to constrain the axial displacement of the fins, resist equipment vibration during operation, and prevent the fins from loosening or shifting.

4. Tube end interface section: Unfolded bare tube sections are reserved at both ends for welding and flange connection, facilitating assembly with heat exchanger tube plates.

Product Features
1. High heat transfer efficiency: The spiral continuous fin structure doubles the effective heat transfer area, reduces the overall volume of the equipment, and lowers equipment investment.

2. Strong adhesion and low thermal resistance: The steel strip is tightly attached to the base pipe, and the end is welded and locked, with low contact thermal resistance, vibration resistance, and long-term operation without easy detachment.

3. High degree of customization of specifications: The material, diameter, wall thickness, fin height, fin spacing, and effective heat transfer length of the base tube can be customized according to the working conditions.

4. Widely applicable working conditions: can be adapted to steam, thermal oil, and high-temperature hot water; The external medium can be air, flue gas, or weakly corrosive process gases.

5. Good airflow performance: spiral fin guide structure, controllable air side resistance, matched with fan system, not easy to block large areas of dust, easy to blow and maintain.

6. Multiple materials to choose from: carbon steel, 304 stainless steel, 316L stainless steel and other materials to meet different on-site requirements for corrosion resistance and high temperature resistance.
