Refractory – Insulation Inspection

An important application of infrared testing is the inspection of insulated process vessels, boilers, and heaters, such as those used in petrochemical industry. These vessels are lined with refractory insulation to protect the metal skin from the high temperatures and caustic properties of the product.

Over time, this insulation deteriorates and must be replaced. An infrared inspection of the exterior surface of the vessel permits thermal mapping of the unit. Temperatures are verified with a surface temperature probe allowing for differences in emissivity.

I appreciate the professional and efficient service provided by ProLine Inspections. Their reports are accurate and well documented.”

The customer is provided with the information necessary to accurately schedule shutdowns so that faulty components can be repaired before they cause severe damage or injury due to failure.

The insulation inside boilers, heaters and ovens will also deteriorate over time. To operate these units safely and cost-effectively, an infrared inspection should be performed on an annual basis. The information provided from an infrared inspection, along with other PM tools will help you maintain your equipment in top condition.
