Pay attention to the corrosion of the metal surface beneath the insulation layer
Thread Content
Figure 1 below shows corrosion on the metal surface used for insulation of the casing in a certain refinery’s benzene unit, while Figure 2 shows corrosion on the metal surface used for insulation of pipes in a certain refinery’s reforming unit. Therefore, due to the severe corrosion present in the insulation layer, it is necessary to address the corrosion and take protective measures beneath it.
The corrosion of metal surfaces beneath the insulation layer cannot be ignored; regular inspections and appropriate anti-corrosion treatments should be carried out. .
