T-shaped finned tube is an important part of reboiler in boiling heat transfer equipment with high efficiency, which fills a gap in boiling heat transfer equipment in China.

T-shaped finned tube was listed in the National Key New Product Plan of the Ninth Five Year Plan by the National Science and Technology Commission. T-type finned tube is formed in one time by non cutting rolling process. T-shaped finned tube is used to replace ordinary smooth tube, so that liquid boiling takes place in the spiral channel of T-shaped finned tube. In the boiling process, due to the rapid circulation of vapor and liquid inside and outside the spiral channel, efficient liquid film evaporation is formed in the channel, which greatly improves the heat transfer coefficient, and can also prevent scaling in the high-speed circulation process. Compared with the ordinary plain tube reboiler, the T-shaped finned tube reboiler not only has higher heat transfer efficiency, but also has the advantages of low wall temperature required for boiling, high critical heat load, stable operation, and large elasticity. It has achieved significant economic benefits after being applied in the petrochemical industry and other fields.

The heat transfer efficiency of T-shaped finned tube is more than or equal to 3 times higher than that of plain tube, and the heat transfer area is saved by more than or equal to 30%. In 1993, T-shaped finned tubes passed the appraisal of scientific and technological achievements organized by Shandong Provincial Science and Technology Commission, filling a gap in domestic boiling heat transfer equipment. The technical level is at the domestic advanced level.

T type finned tube material: 10 #, stainless steel, 08Cr2AlMo Scope of application: applicable to petrochemical, energy and other industrial fields, shell side boiling heat transfer conditions. T-shaped finned tube is not suitable for medium with solid dust and easy coking on the shell.
