ASTM A312 TP347H High Frequency Welding Fin Tube In Air Preheater And Condenser

A312 TP347H HFW Fin Tube Application

• Petrochemical Industry: Heaters, reactors, condensers.
• Power Generation: Boilers, air preheaters, flue gas heat recovery.
• Environmental Protection: Flue gas desulfurization, waste gas treatment.
• Refrigeration and Air Conditioning: Condensers, evaporators, cooling towers.
• Food and Pharmaceutical: Sterilization, drying, and heat exchange equipment.
• Marine and Offshore: Ship engine cooling, seawater desalination.
• Renewable Energy: Solar thermal collectors, geothermal heat exchangers.

A312 TP347H HFW Fin Tube StrengthManufacturing Process

• Efficient heat transfer: The fin structure increases the heat transfer area and significantly improves the heat exchange efficiency.
• Strong corrosion resistance: Stainless steel is suitable for corrosive environment.
• High temperature and high pressure resistance: suitable for high temperature and high pressure conditions.
• Compact structure: Reduce equipment volume and save space.
• Long service life: material and process ensure long-term stable operation.

A312 TP347H HFW Fin Tube Manufacturing Process

High-Frequency Welding: The fins are welded onto the base tube using high-frequency electric currents. This process ensures:

• Strong bond: Creates a seamless and durable connection between the fins and the tube.
• Precision: Ensures uniform fin placement and consistent quality.
• Efficiency: A fast and cost-effective production method.
• Surface Treatment: The tubes may undergo additional treatments, such as pickling, passivation, or polishing, to enhance corrosion resistance and surface smoothness.
