Abstract
To solve the reliability problem of flange connection which is caused by the corrosion of tower equipment in the petrochemical industry and to decrease the accident rate in producing process, the finite element checking method of flange was discussed. Combined with the analysis of engineering project example, a finite element method was put forward to test the intensity and rigidity of the flanges under the combined action of internal and external loads. This method overcame the disadvantages that the check and design standards of flanges only considered the calculation of intensity regardless of the impact of external loads: Firstly, the intensity of the flange connection system was checked to ensure the intensity requirement. Secondly, the sealing characteristic of the flange was calculated, and the leakage situation and trends were predicted according to the stress distribution of the gasket. Finally, a finite element analysis process for pre-judgment of the flange leakage was presented.关键词
