Abstract: The application of bending design for main service piping adopted in 2×1000MW ultrasupercritical units of Shanghai Waigaoqiao Third Power Plant was introduced. The technical advantage of the replacement of elbow by using of bending was analyzed. The comparing of concrete data shows that the adoption of bending design can reduce the investment, decrease the heat consumption rate which is helpful for energy conservation and emission reduction, and the design is beneficial for the piping safe operation simultaneously.
