Products：
-
Aerogel blanket DRT0610（10mm thickness）
-
Aerogel blanket DRT0603（3mm thickness）
-
Operation Conditions：
-
Pipeline diameter：32mm
-
Interior liquid temperature：560℃
-
Pipeline length：4.5km
-
Ambient temperature：30.9℃
-
Challenges：
-
Surface temperature and heat loss due to radiation must be decreased so as to provide a comfortable indoor environment.
-
Installation must be done within confined space because of high density of pipelines.
-
Maintenance is difficult for aerial pipelines.
-
Solution：
-
3 layers of aerogel blanket DRT0610 and 1 layer of aerogel blanket DRT0603 with single-face aluminum foil, tightly wrapped with aluminum foil glass fiber fabric.
Benefits：
After applying aerogel insulation blankets, surface temperature is controlled below 50℃, with improvement of structural strength in insulation. Collapse of and uneven structure of insulation disappear. Improved insulation property with reduced thickness is achieved, allowing application in confined space.
