In the petrochemical production, the sealing performance of the gasket is directly related to the long-term safe operation of the plate heat exchanger. As the production cycle is becoming longer and the process conditions are becoming more and more demanding, the leakage problems caused by gasket seal failure are also becoming more and more obvious. In order to solve the problem of gasket failure and leakage in the heat exchanger, sometimes the flange joint must be welded.
The operating parameters(the pressure of the medium, the temperature and the physical and chemical properties of the medium )have a great influence on the PHE rubber gaskets.Most media operating conditions in petrochemical production are medium and low pressure. Simple pressure and media factors have little effect on gasket leakage. Only when the operating pressure, operating temperature and physical and chemical properties of the medium work together will the gasket seal failure.
