Fatigue Analysis of Liquefied Petroleum Gas Cylinders for Safety Risk Assessment

doi:10.1007/s12204-019-2143-x

Abstract

Abstract: With the widespread application of liquefied petroleum gas (LPG), the safety of LPG cylinder has received more and more attention. For the safety of LPG cylinder, we conduct a safety risk assessment of cylinder using the failure mode and effect analysis (FMEA) method. Taking the most influential inflatable fatigue under normal conditions as the research object, we use FE-safe software to analyze the fatigue failure. The risk compliance coefficients of various failure modes are calculated and classified according to the risk level. In this way, the service life of the LPG cylinder weld is determined. The presented method improves the safety risk assessment process of LPG cylinder and provides a good theoretical and practical basis for similar pressure vessel risk assessment.
