| Surface temperature of insulation | ℃ | 56.5 | 27.8 |
| Heat loss after insulation | W/m | 586.4 | 108.8 |
| Energy conservation rate | 81% | ||
| Plus and minus | Cracks, collapse and heat leakage from gaps happen, uneven insulation structure | Even insulation structure, no heat leakage from gaps |
After replacement of aerogel, heat loss of high pressure steam pipelines in Coal Industry was decreased by 81%. After replacement of aerogel, overall structure of the pipelines is stronger than before.
