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.
