The next three pictures show hot water/steam pipelines, in Russia, which move hot water/steam to buildings for heating and hot water in the buildings.

These hot water/steam pipelines are coated with approximately 100 mils/2.5mm of TC Ceramic. For the most part, these hot water pipelines are typically above ground, insulated with asbestos and the insulation is falling off.

Other than coating many such hot water pipe lines and the fact the TC Coating seems to be satisfactory, we have no additional information.
