How to deal with the aging of the plate heat exchanger gasket

Everything has a service life, and the gasket of the plate heat exchanger is no exception, but there is no need to worry about it. The main reason is to replace the aging gasket, and the plate heat exchanger will still work normally.


After the gasket is aging, the plate heat exchanger will leak. In order to deal with the leakage caused by the aging of the gasket, it is allowed to stop the sealing function scheduling for the heat exchanger, that is, tighten the bolts of the combined plate heat exchanger again to schedule each heat exchanger The pressing force of the elastic sealing gasket between the devices can handle the dripping results.



For plate heat exchangers that do not give the stress scheduling field in the nameplate, the stress value is generally given in the overall machine diagram. When tightening this type of plate heat exchanger, the tightening torque should not be lower than the drawing rules in any case. The value, because it has nothing to do with the assembly quality and assembly deformation of the plate heat exchanger. When the tightening torque reaches the request of the regular value, the conversion of the elastic gasket can be stopped in a planned way. For serious production equipment and corrosive media It is recommended to have a set of spare seals for the plate heat exchangers used in this article. When the warehouse temperature is 18°C, the seals of the plate heat exchanger can be stored for 3 years in a transparent plastic package.


The tightening force of the plate heat exchanger, each time the nut is tightened, the nut can be screwed out 3mm, and the stress situation of the control sheet is always paid attention to during the tightening process, and it is only allowed for the heat exchanger with no mission pressure at room temperature. The mediation of the tightening force is aborted to prevent dripping.
