Do inorganic salt crystals containing crystal water tend to cause pipe blockages?

Does evaporative concentration of inorganic salt crystals containing crystalline water easily cause pipe blockages?
This tends to form scabs that block the pipes, and it’s not easy to deal with.
Looking at pipe materials and crystalline substances, in general, crystals accumulate layer by layer inside the pipes, causing holes to become blocked.
It will definitely cause blockages in the pipes, but appropriate methods can be used to avoid such blockages.
It’s true that pipes can get clogged easily, but there are ways to avoid this. In this process, the reflux of the mother liquor is very important; by controlling its amount appropriately, clogging can be prevented.
If wall formation occurs during the evaporation process, it indicates that the crystallization process was not properly controlled; either a large heat transfer temperature difference led to explosive nucleation or the growth process caused this issue.
The higher the crystal content in the slurry, the more likely it is to become clogged; therefore, an appropriate crystal concentration must be maintained, as well as an effective heat-insulation effect.
During the evaporation process, crystallization should be avoided, and the concentration of the liquid exiting the system needs to be properly controlled. Crystallization is carried out in a crystallizer, after which it is directly fed into a centrifuge for separation.
How can pipeline clogging be avoided during design?
