Is there a calculator for thermal losses in superheated steam pipes?

There are currently two medium-pressure superheated steam pipes, with diameters of Φ108 and Φ89; the steam temperature is 380 degrees, and the pressure is 3.0 MPa. Previously, after insulating the pipeline bundle, the temperature of the pipeline casing was 69 degrees; after the insulation modification, the surface temperature dropped to 49 degrees. I would like to know how much steam can be saved per 100 square meters in 24 hours as a result of this 20-degree decrease in the pipeline surface temperature I’m really stuck trying to calculate it; I would be extremely grateful if that expert could help with the calculation. Insulation is made of rock wool + aluminum silicate + insulation coating, so I have no idea how to calculate it. Everyone, please help out. Thank you

Aspen? Or a simplified empirical formula?
