Plate Heat Exchanger Cleaning

Heat exchanger is the common equipment you can found in the power plant process. The reasons why I put plate heat exchanger cleaning is to share what is needed to be done on the old or defective plate heat exchanger on my machine.

In order to make heat exchanger function properly, all tubes must be cleaned and free from any debris. Heating and cooling process in the heat exchanger also contribute to debris growth and corrosions, besides dirty water in the pipeline.

Normally what we did on the heat exchanger cleaning is including checking, regasketing, dye penetrant testing, and chemical services and repressing of deformed plates.
