After replacement of aerogel, heat loss of the pipelines in CNOOC Petroleum Chemical Co.,Ltd . was decreased by 14.9%.
After applying aerogel insulation blankets, surface temperature is controlled below 50℃, with improvement of structural strength in insulation.
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.
According to the comparison between before reform and after reform, the injection steam pipeline from 3rd thermal supply station to
Glass fiber fabric with single-face aluminum foil was applied in between every 2 layers of aerogel blanket to prevent heat leakage from the gaps.
After replacement of aerogel, heat loss of the mid-pressure indoor steam pipelines in SINOPEC Beijing Yanshan Company was decreased by 45.3%, overall structure of the
After insulation with aerogel blanket, the outer surface of insulation is controlled within 50℃, which is a big improvement of working environment
According to the requirement, the allowed maximum of heat loss for seasonal operation is 308W/m2, the allowed maximum of heat loss for annual operation is 186W/m2. Such requirement cannot be satisfied by rock wool
