Product Description

Studded tubes are engineered components commonly used in heat exchangers and boilers. The strategically placed studs on the exterior surface significantly increase the effective surface area, dramatically improving heat transfer efficiency. This makes studded tubes particularly valuable in applications where optimal heat exchange is critical, including industrial processes, power generation systems, and petrochemical plants.

Key Applications in Heater Systems
  • Heater Coils: Enhances heat transfer efficiency by increasing available surface area for thermal exchange
  • Combustion Chamber: Improves heat transfer rates and overall system efficiency
  • Radiant Section: Maximizes heat transfer between hot gases and internal process fluid
  • Convection Section: Optimizes heat transfer from flue gases to process fluid
