ASTM A179 ALuminium Carbon Steel Embeded Fin Tube for Heat Exchanger and Cooling System
Finned tube is a kind of heat exchange element. It is to increase the heat transfer efficiency, usually by adding fins on the surface of the heat exchanger tube to increase the external surface area (or internal surface area) of the heat exchanger tube, so as to achieve the purpose of improving the heat transfer efficiency.
Embeded Fin Tube
Inlaid spiral finned tubes are pre machined with spiral grooves of a certain width and depth on steel pipes, and then the steel strip is embedded on the steel pipe on a lathe. During the winding process, due to a certain amount of pre tension, the steel strip will be tightly trapped in the spiral groove, resulting in a certain contact area between the steel strip and the steel pipe. To prevent the steel strip from rebounding and falling off, both ends of the steel strip should be welded to the steel pipe. For ease of installation, there should be a certain side gap between the steel strip and the spiral groove. If the side gap is too small, forming interference, the inlay process is difficult to proceed smoothly. In addition, the wrapped steel strip always has a certain rebound, which results in poor bonding between the steel strip and the bottom surface of the spiral groove. Inlaying fins can be done on general equipment at a low cost, but the process is complex and the production efficiency is low.
ASTM A179 seamless carbon tube produced by YUHONG GROUP has the following advantages: high dimensional accuracy, high strength, good corrosion resistance, and good finish. ASTM A179 pipe is delivered in the annealed, normalized, normalized and tempered condition. And also provide value-added manufacturing services: bevel end, black oil surface, galvanized surface treatment, anti-corrosion oil, machining.
