Is the insulation of such pipes reasonable?

The pipeline diagram shows the damage to the pipeline insulation of a petrochemical company. It can be seen that the surface corrosion of the pipeline is severe. How to avoid such corrosion?
This is not a stainless steel pipe. It looks like low alloy steel or carbon steel. Don’t think too much about CUI. Just re-insulate and insulate the aluminum skin to prevent rainwater from entering. There are too many like this. In chemical industry units
Exterior corrosion caused by rainwater entering. Just remove it and re-cover it with insulating aluminum skin.
The outer layer of insulation is damaged and corroded by exposure to rain and air. Replace the outer layer of insulation!
This kind of insulation bolts are corroded, making maintenance and repair difficult.
Normally, it is still necessary to remove rust and paint to prevent corrosion before doing insulation, but many do not do this to save costs. The valve is usually made into a custom-made box, and the overlapping seams are wrapped in tin foil.
Remove rust and prevent corrosion, and re-insulate. CUI is likely to occur when the operating temperature is between 20 and 100 degrees. It is recommended to extend the inspection.
