Stress analysis plays an important part in the safety connection of the chemical pipe with the machine,equipment and civil structure. CAESARII,one of stress analysis softwares has obvious advantage and widely used in the petrochemicals, power, steel industry and so on. This paper mainly introduces the pipe stress analysis. At the same time,CAESARII is used to analyze the inlet pipe of the bottom reboiler of light naphtha isomerization. Then the pipe flexibility is optimized through comparing pipe stress and the stress distribution of tower and reboiler inlet of different pipe design projects to fulfil its optimal design.
