Product Overview

Studded tubes are precision-engineered components designed for heat exchangers and boilers. The strategically placed studs on the exterior surface significantly increase the effective surface area, dramatically improving heat transfer efficiency. These tubes are essential for applications requiring optimal thermal exchange in 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
