Abstract
The thermal pipeline is important to play an important role in the operation of thermal power plant equipment, and the safe and stable operation of the body and accessories is very important. The elbow, as an indispensable part of the thermal pipeline, directly affects the safety of the unit. On the basis of the GB/T 16507-2013 “Water Pipe Boiler” standard, this article uses the simulation simulation software to analyze the stress of 90 ° elbow under different bending radius. Distribution status. The calculation results show that: under the same wall thickness, the maximum stress is concentrated in the inner arc. As the curved radius R increases, the maximum stress of the inner arc gradually decreases. At the same time Instead, it gradually increased. Under different wall thickness, the maximum stress occurs at the outer arc.
