Interface leakage refers to the leakage that occurs between the gasket and the flange sealing surface due to poor fitting between them, which can be caused by insufficient gasket compression stress, rough flange sealing surface, thermal deformation or mechanical deformation of the pipeline, vibration, etc. In addition, under operating conditions, the bolt-flange connection may also lead to leakage between the gasket and the flange sealing surface due to bolt deformation and elongation caused by temperature and pressure, creep relaxation and decreased resilience of the gasket, as well as aging and deterioration of the gasket material. Such leakage occurring between the gasket and the flange sealing surface is called "interface leakage.Analysis of Core Causes of Interface Leakage,Installation Stage and Initial Seal Failure,Operation Stage and Long-term Seal Failure.Only by paying attention to sealing details can the safe, efficient, and environmentally friendly operation of the system be guaranteed.
