Recent question;
We have pumps pipe lines coated with ceramic inside, it gives the pipes longer life. I am trying to detect the coated pipe line issues with thermography. Is there any way we can detect issues with ceramic lines pipe with using thermography?

Refractory lined pipework, including ceramic, will cause local hot spots where the lining has deteriorated (assuming a hot fluid in the pipe). Thermography should be helpful in identifying local problems. This type of pipework is usually used where very hot fluids are being pumped around a facility. There is normally a significant temperature differential between the fluid and the ambient temperatures. This means there should be a significant thermal resistance. A local breakdown will lead to a local hotspot on the pipe. What you see with your camera depends on the temperature of the fluid, the ambient temperature, type of pipe, type of ceramic, type of defect, surface of pipe.
