‍               Working conditions:Steam temperature of 520℃，DN300 pipelines

‍

                Solution：

         Traditional insulation solutions：Aluminum silicate ，150mm× 1 layer + Rock wool ，150mm× 1 layer

        Aerogel insulation blanket (UG550) ，10 mm × 4 layers + Aluminum silicate ，150 mm× 1 layer

                         Surface temperature of the traditional insulation project is 38°C, and temperature drop is 25.3°C. After installing the aerogel 

                insulation surface temperature will drop to 37°C, and temperature drop is 15.8 °C, which meets the customer’s requirements.
