What are the application areas of nano-insulation boards on DN1100 large-diameter pipelines? DN (Diameter Nominal) is the unit for the nominal diameter of pipeline systems. DN1100 indicates that the inner diameter of the pipeline is approximately 1100 millimeters (i.e., 1.1 meters), commonly used in large-scale thermal pipelines, flue gas pipelines, main steam pipes, etc. Such large diameters are commonly found in high-energy consumption, high-temperature transmission systems, which have extremely high requirements for insulation performance, space constraints, and energy conservation. Nano-insulation boards are characterized by their ultra-thin, high efficiency, and low thermal conductivity.
