Tightness of flange joints: a case study

abstract

en

A case from industrial practice with history of insufficient tightness resulting in leaks is investigated using FEA. The flange joint is modeled in software ANSYS with parts of adjacent shells to take their effect into account. Goal of the analyses is estimation of gasket contact pressures resulting from load history. The pressures are directly related to the seal tightness. Lastly, effect of shell shape modification on the gasket pressures is also investigated and the results are compared with those from the original configuration. Effects of resulting pressures on seal tightness are discussed.
