Studded Tubes Overview

Also known as nail head tubes or nail-like ribbed tubes, studded fin tubes are widely used in petrochemical industries, particularly in the convection chambers of tubular furnaces to enhance heat transfer effects.

Material Composition

Typically constructed from materials such as carbon steel, stainless steel, alloy or copper, providing durability and resistance to corrosion.

Key Advantages
  • Corrosion resistance, wear resistance, low contact thermal resistance, high stability
  • Studs disrupt fluid flow for better mixing and improved thermal performance
  • Significantly improves heat exchange efficiency compared to smooth tubes
  • Robust construction suitable for harsh operating conditions including high temperatures and pressures
  • Versatile applications across oil and gas, chemical processing, and power generation industries
Applications
  • Cooling systems: Cooling towers, condensers, and evaporators where efficient heat dissipation is essential
  • Fired Heaters: Thermal process equipment to enhance heat transfer efficiency
  • Marine Applications: Ship cooling systems and marine heat exchangers requiring robust performance
  • Industrial Equipment: Heat exchangers, boilers, furnaces and refineries for power generation, petrochemical processes, and HVAC systems
