High temperature insulation systems are widely used in refinery piping, steam networks, petrochemical plants, power stations, and industrial process equipment.
For many years, Calcium Silicate insulation has been one of the standard materials used in these systems because of its compressive strength and high temperature resistance.
But insulation projects today face different requirements.
Pipe layouts are tighter.
Maintenance cycles are longer.
Offshore systems require lighter insulation structures.
Energy efficiency targets are higher.
CUI risk receives more attention during plant operation.
Because of this, more EPC contractors and industrial insulation companies are evaluating Aerogel Blanket for refinery piping, LNG facilities, offshore modules, and industrial process systems.
The comparison is no longer only about insulation material price.
Industrial projects now focus more on:
- Thermal conductivity
- Installation thickness
- Maintenance accessibility
- Moisture resistance
- Transportation weight
- Lifecycle operating cost
What Is Aerogel Blanket?
Aerogel Blanket is a flexible thermal insulation material made from silica aerogel and reinforced fiber carriers.
The material is widely used in:
- Refinery insulation systems
- LNG insulation
- Petrochemical piping
- Offshore platforms
- Industrial equipment insulation
- Cryogenic systems
- High temperature process piping
Compared with rigid insulation materials, Aerogel Blanket provides:
- Lower thermal conductivity
- Reduced insulation thickness
- Better flexibility
- Lower system weight
- Hydrophobic performance
- Easier installation around valves and elbows
Many industrial insulation contractors now use Aerogel Blanket in refinery revamp projects where installation space is limited and maintenance accessibility is important.
Several EPC companies also source Aerogel Blanket directly from manufacturers in China for offshore insulation systems and large industrial piping projects.
What Is Calcium Silicate Insulation?
Calcium Silicate insulation is a rigid insulation material mainly used for high temperature industrial applications.
Common applications include:
- Steam pipe insulation
- Boiler systems
- Refinery process piping
- Turbine insulation
- Industrial furnace systems
- Power plant equipment
The material is usually supplied as:
- Pipe sections
- Rigid insulation blocks
- High density insulation boards
Calcium Silicate insulation performs well in systems requiring rigid structural strength and high compressive load resistance.
The material remains widely used in conventional industrial insulation projects.
The main limitations appear in applications involving:
- Compact pipe systems
- Complex pipe routing
- Offshore environments
- Moisture exposure
- Frequent maintenance access
Aerogel Blanket vs Calcium Silicate: Property Comparison
| Property | Aerogel Blanket | Calcium Silicate |
|---|---|---|
| Structure | Flexible | Rigid |
| Thermal Conductivity | Lower | Higher |
| Insulation Thickness | Thinner | Thicker |
| Weight | Lightweight | Heavy |
| Water Resistance | Better | Lower |
| Installation Flexibility | Better | Limited |
| CUI Resistance | Better | Moderate |
| Compressive Strength | Moderate | Higher |
| Maintenance Accessibility | Better | Lower |
Thermal Conductivity Comparison
Thermal conductivity directly affects heat loss and insulation thickness.
| Material | Thermal Conductivity |
|---|---|
| Aerogel Blanket | 0.015–0.025 W/m·K |
| Calcium Silicate | 0.050–0.070 W/m·K |
Lower thermal conductivity allows thinner insulation layers under the same operating conditions.
This becomes important in:
- Refinery revamp projects
- Offshore modules
- LNG skids
- Pipe rack systems
- Compact industrial facilities
In many industrial plants, thick rigid insulation creates installation conflicts around:
- Valves
- Pipe supports
- Flanges
- Small bore piping
- Instrument connections
Aerogel Blanket reduces insulation thickness while improving maintenance access.
This is one reason many industrial insulation distributors now purchase aerogel insulation materials for compact piping systems and high density process units.
Thickness Comparison
| Application | Aerogel Blanket | Calcium Silicate |
|---|---|---|
| Steam Pipe | 5–25 mm | 40–60 mm |
| High Temperature Pipe | 20–30 mm | 50–80 mm |
| Valve Insulation | Easier | More Difficult |
| Compact Pipe Rack | Better Fit | Space Limitation Risk |
Reduced insulation thickness creates several engineering advantages:
- Easier pipe routing
- Better maintenance access
- Lower transportation weight
- Reduced structural load
- Improved modular fabrication
Flexible insulation materials also simplify installation around complex piping geometry.
Moisture Resistance and CUI Risk
CUI remains one of the main maintenance problems in refinery and offshore facilities.
Calcium Silicate insulation can absorb moisture during long-term operation in outdoor or high humidity environments.
Common high-risk environments include:
- Offshore platforms
- Coastal refineries
- Outdoor steam piping
- Marine process systems
Moisture trapped inside insulation systems increases corrosion risk under metal cladding.
Aerogel Blanket contains hydrophobic properties that help reduce water penetration and moisture retention.
For refinery maintenance teams, this means:
- Lower CUI risk
- Reduced shutdown maintenance
- Longer insulation lifespan
- Lower corrosion repair cost
Several refinery operators now specify hydrophobic insulation systems for critical outdoor piping and offshore equipment insulation.
Moisture Resistance Comparison
| Condition | Aerogel Blanket | Calcium Silicate |
|---|---|---|
| Water Absorption | Very Low | Moderate |
| Hydrophobic Structure | Yes | No |
| Offshore Suitability | High | Moderate |
| Long-Term Moisture Stability | Better | Lower |
| CUI Prevention Performance | Better | Moderate |
Installation Efficiency Comparison
Installation labor directly affects insulation project cost.
Calcium Silicate insulation generally requires:
- Cutting rigid sections
- Larger insulation thickness
- Additional support structures
- More installation space
Rigid insulation materials are more difficult to install around:
- Pipe elbows
- Valves
- Flanges
- Irregular equipment surfaces
Aerogel Blanket is flexible and easier to cut and wrap around complex industrial piping systems.
This improves installation efficiency during:
- Refinery shutdown maintenance
- Offshore module fabrication
- LNG construction projects
- Pipe rack retrofits
Installation Comparison
| Installation Factor | Aerogel Blanket | Calcium Silicate |
|---|---|---|
| Flexibility | Better | Rigid |
| Valve Installation | Easier | Difficult |
| Elbow Wrapping | Easier | Difficult |
| Transportation Weight | Lower | Higher |
| Installation Labor | Lower | Higher |
| Maintenance Access | Better | Lower |
Many insulation contractors now work directly with aerogel blanket manufacturers in China for customized insulation systems used in refinery piping and offshore engineering projects.
High Temperature Applications
Calcium Silicate insulation has long been used in high temperature industrial systems.
Aerogel Blanket is increasingly used in similar operating environments because of reduced insulation thickness and improved installation flexibility.
Typical applications include:
- Steam piping
- Refinery process units
- Turbine systems
- Furnace piping
- Exhaust systems
- Heat exchangers
- Process vessels
- Industrial reactors
- Pipe supports
- Equipment insulation covers
Several industrial insulation suppliers now provide custom Aerogel Blanket solutions for high temperature industrial projects requiring lightweight insulation systems and reduced maintenance risk.
Industrial Application Comparison

|---|---|---|
| Refinery Piping | Excellent | Common |
| Offshore Platforms | Excellent | Moderate |
| Steam Systems | Excellent | Good |
| Compact Pipe Rack | Excellent | Limited |
| LNG Facilities | Excellent | Limited |
| Heavy Load Areas | Moderate | Excellent |
