The nail head tube (studded fin tube) is also called nail like ribbed tube. In petrochemical industry, nail head pipe is widely used. Especially in the convection chamber of the tubular furnace, in order to enhance the heat transfer effect outside the tube, the heat transfer element often adopts the nail head tube.
Material: Typically constructed from materials such as carbon steel, stainless steel, alloy or copper, providing durability and resistance to corrosion.
Cooling systems
Common in cooling towers, condensers, and evaporators, where efficient heat dissipation is essential.
Fired Heaters
Employed in fired heaters and other thermal process equipment to enhance heat transfer efficiency.
Marine Applications
Used in ship cooling systems and other marine heat exchangers where robust performance is required.
Heat exchangers, boilers, furnaces and refineries
Widely used in industrial heat exchangers for power generation, petrochemical processes, and HVAC systems.
