High-Frequency Welded (HFW) Helical Finned Tubes are high-efficiency heat transfer elements designed for heavy-duty thermal applications. Datang Finned Tube offers a comprehensive range of standard specifications as well as custom dimensions tailored to your engineering requirements. High-Frequency Welded (HFW) Helical Finned Tubes Key Manufacturing Capability & Specifications: Base Tube Material:

An fin fan cooler heat exchanger (ACHE) is a specialized type of heat exchanger. Fin-fan heat exchangers operate on the synergistic principle of thermal conduction and forced convection. By utilizing fins to extend the surface area, they use air as the cooling medium to transfer heat effectively. ACHE fans come

In heat exchanger design and selection, finned tubes (featuring Datang Finned Tube solutions) and bare tubes (also referred to as plain tubes) are two fundamental heat transfer components. Their core difference stems from the size of their heat exchange surface area, directly determining their suitable working conditions and application scenarios.

Studded tubes, as high-efficiency enhanced heat transfer elements, are widely used in industrial scenarios such as waste heat boiler economizers, petrochemical fired heaters, power generation equipment, incinerators, and heavy oil hydroprocessing units in refineries. They consist of a base tube with high-density cylindrical metal studs welded onto its surface, typically

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

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
