Customer Profile：
Company：SINOPEC Beijing Yanshan Company
Project Location：SINOPEC Beijing Yanshan Company
Equipment/pipeline： Aboveground, mid-pressure indoor steam pipelines
Operation Conditions：
Operation temperature：540℃
Pipeline diameter：φ426×18mm
Pipeline pressure：3.6MPa
No wind indoor
1, Surface after insulation and thickness required for insulation must be reduced in order to improve indoor environment.
2, Thermal bridges associated with pipe racks must be stopped in order to further minimized heat loss.
Products：
Aerogel blanket DRT0610（10mm thickness）
Solution：
7 layers of aerogel blanket DRT0610 with aluminum foil
Noted: 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.

Benefits：
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 pipelines is stronger than before. A drop of 13℃ of surface temperature of insulation enhances personal safety and improves working environment.
