Because of its structural characteristics, the serpentine high-pressure heater has thinner tubesheet compared with the traditional U-tube high-pressure heater, which solves the bottleneck of tubesheet manufacturing and becomes an important auxiliary machine for millions of secondary reheating units in the future. In this paper, the typical working conditions are selected, and the bending design methods of domestic and foreign serpentine tubes are adopted respectively. The results show that compared with Chinese standards, the bending can be thinned. Subsequent tests and finite element simulations verify the reliability of foreign methods and explore the optimization design methods of domestic serpentine tubes.
