G-type finned tube Classification and Concepts: To enhance heat transfer efficiency, the total surface area (or internal surface area) of heat exchanger tubes is typically increased by attaching fins to their surfaces, thereby improving heat exchange performance. Such heat-exchange tubes are referred to as finned tubes. Finned tubes can be categorized according to their shape and structure into square-fin tubes, spiral-fin tubes, vertical-fin tubes, helical‑serrated fin tubes, and internally finned tubes. Based on material, they may be classified as single‑metal finned tubes or bimetallic composite finned tubes. Furthermore, finned tubes can be manufactured using various processes, including roll‑formed fins, welded‑formed fins, roll‑formed fins, and integral‑molded fins.

Finned tubes are heat‑exchanger tubes with fins attached to their surfaces, and they constitute a type of heat‑exchange component. These fins increase the surface area, thereby enhancing heat transfer efficiency. Since finned tubes are installed in boilers and other mechanical equipment, they must withstand prolonged exposure to high temperatures. Therefore, when selecting finned tubes, it is essential to choose models that possess the following characteristics: 1) Excellent corrosion resistance; if the selected tubes lack sufficient corrosion resistance, they will readily corrode under sustained high‑temperature conditions. 2) High wear resistance; as wear on the fins can impair heat‑transfer performance, it is crucial to select finned tubes with robust abrasion resistance.
