This paper discusses the flexible design method of chemical pipeline under the support of stress analysis,establishes the pipeline model through the example analysis and carries on the stress check.Therefore,the design scheme of adjusting the position and type of support and hanger is put forward,and the stress distribution of pipeline is optimized by simulation analysis.The results show that the adjusted design scheme effectively reduces the secondary stress level and ensures the safety and stability of the pipeline system.This study provides a scientific basis for the design of chemical pipelines and has a positive significance for improving the efficiency of pipeline maintenance and repair.
