Fin star tube

The finned star tube is a heat exchange star-shaped finned tube of a vaporizer. It is used together with the heat exchange square connector. It is the main component on the vaporizer and belongs to the technical field of air separation industry. It mainly uses a finned tube to connect 8-16 pieces of heat exchange fins, wherein the joints are connected at the top of the four heat exchange fins evenly spaced. The utility model has the advantages of simple structure, compactness and reasonableness; low production cost, convenient processing and beautiful appearance; when used in conjunction with the connecting body, it is not deformed or pulled off on the vaporizer; the performance of the vaporizer can be improved, and the performance is stable and reliable. It has high thermal efficiency and wide application. It can be widely used in air separation industries such as oxygen stations and steel plants. The liquid gas is vaporized into a certain temperature to meet the various needs of industrial and civilian use. The star tube is mainly used for liquefied natural gas equipment, LNG equipment and CNG filling stations. Commonly used materials are 6063, 3A21, LF21, 6063T5 and other brands.
Fin star tube performance
The finned star tube is a kind of high-strength hard aluminum, which can be heat-treated and strengthened. It has moderate plasticity in annealing, quenching and hot state. The spot welding is good. The aluminum tube has intergranular cracks during gas welding and argon arc welding. The tendency of the aluminum tube to be cut after quenching and cold work hardening is poor in the annealed state. The corrosion resistance is not high, and the anodizing treatment and painting method or the surface is coated with an aluminum layer to improve the corrosion resistance. It can also be used as a mold material.
