Stress-Strain Analysis of Reducing Pipe Under Temperature

XUE Jinghong;CHU Yanghua;College of Civil Engineering and Architecture,Northeast Petroleum University;  
In the event of thermal expansion and contraction in the pipeline,thermal stress is generated. Due to the existence of thermal stress,the pipe is stretched and contracted to cause deformation of the pipe and damage may occur at the pipe diameter. In this paper,the finite element software ANSYS is used for modeling and analysis,and the eight-node solid solid element model is used to simulate the variable pipe. The influence of temperature on the diameter of the pipeline is studied. The influence of the temperature difference on the variable pipe is studied. The results show that the weak position of the variable pipe is located around the change of the pipeline under the action of temperature. The limit stress of the variable pipe is related to the temperature and temperature of the pipeline. The study provides a reference for the design of thermal pipelines,making the heat transfer variable diameter pipeline design reasonable energy saving.
