Infrared Imaging
Refractory
Petrochemical industries, like other process industries, generally benefit from electrical/mechanical thermography inspections. Infrared inspection of various refractory lined vessels is an extremely cost effective process.
The condition of refractory lining is extremely critical to vessel integrity and the safety of various high temperature applications such as boilers, furnaces, dryers, process vessels, rotating kilns, off gas ducting and cyclones.

Some of the anomalies that can be detected are refractory wear, refractory loss, blockages and sintering.
In a process furnace inspection, infrared is used to inspect heater tubes for carbon build-up. This effect of this buildup is known as coking, which eventually leads to higher furnace firing rates and increases tube temperature, resulting in reduced tube life.
