What type of inspection should be frequently performed on piping that is internally insulated?

• A. Ultrasonic testing
• B. Visual inspection for hot spots
• C. X-ray inspection
• D. Radiography testing

Answer: (B)

Choosing visual inspection for hot spots as the most appropriate method for inspecting piping that is internally insulated is well-founded. Internally insulated piping can often conceal issues such as corrosion under insulation (CUI), which can lead to significant integrity problems if left unchecked. Visual inspection allows the inspector to look for signs of thermal anomalies or unusual heat patterns on the outer surface of the insulation. Hot spots may indicate that there is degradation or damage to the pipe beneath, such as corrosion or other forms of material failure. Detecting these anomalies through visual means is critical, as it provides immediate, observable data regarding the condition of the piping system. While other inspection methods like ultrasonic testing and radiography testing offer valuable insights into material integrity and can detect issues not visible on the surface, they do not directly assess the surface condition in relation to thermal performance and can be expensive or impractical in certain situations. Visual inspection provides a cost-effective, accessible first step in monitoring the condition of insulated piping and can often lead to more detailed investigations if anomalies are observed.
