Why Choose Aerogel for Steam Lines?
1. Superior Thermal Efficiency: Aerogel has a nanoscale porous structure with extremely low thermal conductivity (approximately 0.018 W/(m·K) at room temperature). This means that while achieving the same insulation effect, its thickness is only 1/3 to 1/5 of traditional materials.
2. Prevention of Corrosion Under Insulation (CUI Defense): Corrosion under insulation (CUI) is a major concern for steam lines. Our aerogel blankets have excellent hydrophobic properties, preventing moisture from entering the pipe surface, while their breathability allows internal moisture to escape, significantly extending the pipe's lifespan.
3. Space and Logistics Savings: Due to its extremely thin thickness, it is ideal for confined spaces (such as pipe racks and areas with dense piping). The thinner volume also means that a larger area can be loaded in a single shipment, reducing logistics and storage costs.
4. Stable physical properties (long-term durability): Unlike rock wool, which is prone to settling or water absorption failure, aerogel structures can maintain their shape stability under vibration, impact and extreme temperature difference cycles, and have a service life of more than 20 years.

Our Aerogel blanket is flexible and easy to cut using standard tools. It can be wrapped around complex shapes, valves, and flanges with minimal waste.
Step 1: Measure pipe circumference.
Step 2: Cut aerogel blanket to size.
Step 3: Wrap and secure with Stainless Steel Cable Ties (recommended for high-temp stability).
Application
Industrial Steam Piping: High-pressure and low-pressure steam distribution lines.
Refineries & Petrochemical: Insulation for distillation columns and process piping.
Power Plants: Efficient thermal barriers for turbines and high-temperature exhausts.
District Heating: Underground steam pipe networks where space is limited.
Aerogel Insulation Blanket Selection suggestions:
High temperature scenario: Ceramic Fiber aerogel blanket + ceramic fiber backing layer is preferred to form a double-layer thermal barrier.
Low temperature deep cooling: Fiberglass aerogel blanket + vacuum insulation layer is used to reduce the cold loss by another 15%.
New energy field: Pre-Oxidized PAN aerogel pad + fireproof coating is recommended to take into account both heat insulation and flame retardancy
| Type | Reinforcing Fiber | Temperature Range | Thermal Conductivity (at 25°C) | Advantages & Limitations |
| Fiberglass Aerogel | Glass fiber | -200°C to 650°C | 0.015–0.03 W/(m·K) | Excellent flexibility, cost-effective; limited high-temperature resistance |
| Ceramic Fiber | Ceramic fiber | >600℃ | 0.020–0.025 W/(m·K) | Exceptional thermal shock resistance, high-temperature durability; higher cost |
FAQ:
What is the maximum temperature for Aerogel Insulation?
Our silica aerogel blankets are rated for continuous service up to 650°C (1200°F), making them ideal for superheated steam lines.
Is it environmentally friendly?
Yes. It is non-combustible, inorganic, and does not contain harmful fibers or VOCs.
Can it be reused?
Unlike rigid insulation, aerogel blankets can be removed and re-installed after pipe inspections, saving material costs.
