Wound Tube Heat Exchanger

·Spiral Wound Structure: Spirally arranged heat exchange tubes enhance media turbulence and improve heat transfer efficiency.
·Anti-Fouling Property: The spiral flow path reduces material deposition and slows fouling adhesion.
·High Pressure Adaptation: The shell-and-tube structure withstands high working pressure and temperature conditions.
·Compact Design: Large heat exchange area per unit volume reduces equipment installation space requirements.
·Excellent Heat Transfer Efficiency: The counter-wound structure and spiral flow design significantly improve heat transfer performance compared to traditional heat exchangers, resulting in minimal heat loss and effective control of the temperature difference between the hot and cold ends.
·Compact and Energy-Efficient Design: With a small footprint, lightweight construction, and low metal consumption, combined with high heat recovery efficiency, this design reduces energy consumption and lowers operating costs.
·Long-term stable operation: The design without expansion joints reduces the risk of failure, offers high fatigue strength, and is suitable for industrial applications requiring continuous operation, resulting in low maintenance costs.

·Structure Form: Shell-and-tube structure with spirally wound heat exchange tubes inside.
·Connection Method: Flanged connections compatible with standard industrial piping.
·Contact Material: Shell and heat exchange tubes made of stainless steel 304/316L.
·Flow Path: Countercurrent flow of media in tube side and shell side, supporting countercurrent heat exchange.
·Applicable Conditions: Adapts to high-temperature, high-pressure, and media containing minor impurities.
·Maintenance Methods: Supports online cleaning and chemical cleaning to reduce maintenance costs.

·Chemical Industry: Heating, cooling, and condensation of process media, as well as waste heat recovery processes.
·Food Industry: High-temperature sterilization and cooling links in dairy and beverage production.
·HVAC Systems: Heat exchange in central heating and industrial waste heat recovery systems.
·Energy Industry: Steam condensation, heat transfer oil heat exchange, and heat recovery of high-temperature media.

·Reduced Heat Exchange Efficiency with Non-compliant Media Outlet Temperature
Check fouling on the inner and outer tube walls; confirm stable media flow and pressure; verify that the temperature difference between inlet and outlet media is within the design range.
·Media Leakage at Flanged Connections
Check if flange gaskets are aged or damaged; confirm flange faces for scratches or corrosion; tighten bolts evenly to the specified torque.
·Vibration or Noise During Equipment Operation
Check if media flow rate exceeds the design range; confirm loose shell supports; troubleshoot cavitation in the media.

·Ensure clean flange faces during installation, align gaskets correctly, and tighten bolts evenly in a diagonal sequence.
·Gradually increase pressure and temperature before operation to avoid seal failure due to sudden changes.
·Regularly clean the equipment using chemical cleaning or online cleaning to remove fouling in the flow paths.
·Drain the media inside the equipment during long-term shutdown to prevent pipeline freezing or tube bundle corrosion in low-temperature environments.
