High Temperature Resistance: TP304H has elevated carbon content, making it more stable at high temperatures.
Corrosion Resistance: Excellent resistance to oxidation and various corrosive environments.
Improved Heat Transfer: Serrated fins break the boundary layer, increasing turbulence and heat exchange.
Durability: HFW process ensures strong fin-to-tube bonding, with minimal thermal stress issues.
Reduced Fouling: Stainless steel surfaces resist fouling and scale formation better than carbon steel.
Convection Coils: Ideal for furnaces, boilers, and heat exchangers where high-efficiency heat transfer is required.
Industrial Heating Systems: Used in power plants, chemical plants, and refineries where heat recovery and thermal management are crucial.
Air-Cooled Heat Exchangers: Effective in air-cooled heat exchangers for HVAC systems and cooling towers where compactness and efficiency are essential.
Energy Recovery Systems: Commonly used in waste heat recovery and energy-efficient systems where convection heat transfer is needed to maximize energy savings.
