Fin tube is the core heat transfer element of heat exchangers. Datang is a veteran enterprise in fin tube manufacturing, evolving from early tension-wound fin tubes to high-frequency welded fin tubes, laser-welded fin tubes, and now primarily embedded(G Type) fin tubes and wrapped fin tubes (L / LL / KL […]

Embedded “G” Fin Tubes Introduction Embedded “G” Fin Tubes are widely used in petroleum refining and chemical processing, power plant boilers,air-cooled heat exchangers(ACHE). The aluminum fins are mechanically embedded into a helical groove—typically 0.25 to 0.5 mm deep—cut into the outer surface of the base steel tube. This process ensures

From oil refineries to petrochemical plants, various industrial heat exchange processes rely on heat exchangers to transfer thermal energy. As one of China’s renowned heat exchanger manufacturers, Datang provides a diverse range of heat exchangers for various application fields, backed by strict quality control and advanced technology. Among industrial heat

Finned tubes play a vital role in enhancing heat transfer efficiency across various industries. Their unique design improves the efficiency and effectiveness of heat transfer. By adding fins to the surface of the base tube, the surface area of the tube is increased, expanding the heat transfer area by several

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,

In industrial heat exchange and global supply chains, the process selection for high-efficiency heat exchange elements directly determines system thermal efficiency and operational lifespan. As an industrial manufacturing brand deeply rooted in the international market, Datang Finned Tube strictly executes high-standard quality control systems, providing tailored heat exchange solutions for

Datang Finned Tube — Premium Edge Tension Wound Finned Tubes At Datang Finned Tube, we manufacture high-performance edge tension wound finned tubes,also known as tension-wound, “L” / “LL” / “KL” fin tubes, or wrap-on fin tubes—are enhanced heat transfer components formed by tightly winding a metal strip around a base

A Boiler Economizer (also known as a Flue Gas Waste Heat Recovery System) is a highly efficient energy-saving heat exchanger installed in the tail flue of industrial or power plant boilers. By recovering the low-grade heat from the exhausted flue gas to preheat the boiler feed water, it achieves the
