What is a frequently overlooked issue that occurs during routine inspections of pressure vessels?

Insulation degradation is often a frequently overlooked issue during routine inspections of pressure vessels. Insulation plays a crucial role in maintaining temperature control, thermal efficiency, and protecting personnel from hot surfaces. Over time, insulation can become damaged due to factors such as moisture intrusion, physical wear, or chemical exposure. This degradation can lead to increased energy costs, loss of temperature control, and potentially hazardous conditions if not addressed.

During routine inspections, inspectors may focus primarily on visible components like surface corrosion or support structures without adequately assessing the condition of insulation. This oversight can result in unrecognized thermal inefficiencies or safety risks. By regularly evaluating the integrity of insulation, facilities can mitigate these risks and ensure the overall safety and efficiency of their pressure vessels.
