| Abstract: | Based on piping finite element analysis theory, according to the related standard and combined with one fracture failure case occurred in heat exchanger used aluminum pipe in air separation unit, the local stress distribution in the structure of branch pipe connected to main pipe and the welds around the opening on heat exchanger head was analyzed. The safety assessment for the failed pipeline was carried out. Then, practical measures for reforming were provided and the analysis methods for this kind of piping were proposed. |
