Serrated spiral fin tubes are important parts of advanced heat exchangers, the combination of serrated fins and spiral configurations maximizes heat transfer while maintaining structural integrity.Tube and fin materials may be carbon, stainless steel, copper, ferritic alloy or austenitic alloy steel and can be of similar or dissimilar material combinations.
Serrated finned tubes made from TP304H stainless steel are high-performance heat transfer components designed for extreme furnace environments, where high temperatures, corrosion, and mechanical stress are major challenges.
These tubes combine the excellent heat transfer properties of serrated fins with the superior corrosion and oxidation resistance of TP304H stainless steel, making them ideal for furnaces, reformers, and high-temperature heat exchangers.
Advantages
With a versatile application, suitable for a wide range of industries, including oil and gas, chemical processing, and power generation:
*Heat exchangers, boilers, furnaces and refineries: Ideal for use in various types of heat exchangers, including oil coolers, condensers, and evaporators.
*Power Generation: Commonly used in power plants for efficient heat recovery and steam generation.
*HVAC Systems: Utilized in heating, ventilation, and air conditioning systems to improve energy efficiency.
