Corrosion resistance of all welded plate heat exchanger cleaning
Corrosion resistance of all welded plate heat exchanger cleaning using chemical cleaning corrosion all welded plate heat exchanger, according to the different actual conditions and water quality, please scale scale by qualitative analysis assay preparation medicament cleaning, respectively.
Due to the difficulty of cleaning degree is increased with the increase of scale or sedimentary layer thickness increased rapidly, so the cleaning interval time shoulds not be too long, should according to the characteristics of the production plant, the nature of the heat transfer medium, the corrosion speed and operation cycle, and so on and so forth on a regular basis for inspection, repair and cleaning.
According to the corrosion resistance in the form of all welded plate heat exchanger, should be in corrosion resistance all welded plate heat exchanger with sufficient space to meet the condition (the ends of the
Cleaning and maintenance needs.
Corrosion-resistant all welded plate heat exchanger in the installation, should set aside enough space on both ends so that it can take out and replace the pipe.
And, by using the mechanical method cleaning tube, both ends can be scrubbing operation of pipe.
Corrosion-resistant all welded plate heat exchanger of fixed epicranium end should leave enough space so that he can from the casing spare tube bundle, outside the cranium end must also set aside more than a metre of location to casual split cranium and floating head cover.
Corrosion-resistant all welded plate heat exchanger of fixed epicranium should set aside enough space to take control, also can be in one end of its relative to set aside enough space so as to remove the shell.
