Their main function is to transport the heat energy produced by boilers to indoor heating equipment through heat media such as steam and hot water. After the installation of thermal pipelines, they need to be inspected to check whether the pipelines are damaged or blocked. The traditional inspection method is manual inspection, which has the problems of high labor intensity, low efficiency, easy to be affected by subjective factors, and difficult to implement in some dangerous or complex environments. With the development of automation technology, inspection robots came into being.
