In April, Datang successfully delivered a batch of 200 extruded fin tubes to a customer in the Philippines. Under the tropical climate conditions of Southeast Asia, the food processing industry enforces stringent standards for the energy efficiency and hygiene of drying equipment. Our client, a leading food processing equipment manufacturer
Serrated finned tubes are designed with teeth (serrations) along the fins to expand the heat transfer surface area and enhance thermal efficiency. Compared to solid (plain) finned tubes, radial serrations break up the boundary layer and enhance gas turbulence, boosting heat transfer efficiency by 15% to 20%. However, this also

The operational stability of industrial heat exchangers relies on the precise matching of technical parameters and material properties. In industrial heat exchange systems, welded finned tubes serve as the primary heat transfer elements. In particular, High-Frequency Resistance Welded (HFW) finned tubes achieve a fusion rate of over 95% between the
When selecting finned tubes for air cooled heat exchangers (ACHEs), condensers, or industrial radiators, the choice between Embedded (G-Type) and Extruded fin tubes is one of the most critical decisions. The fundamental difference lies in how the fin is attached to the base tube. which directly dictates their applicable scenarios,
