Calcium Silicate Insulated Pressure Vessels
Calcium silicate insulated pressure vessels utilize rigid calcium silicate insulation to provide high-temperature thermal protection with excellent structural strength. Calcium silicate insulation is manufactured from lime and silica, reinforced with cellulose fibers, creating a rigid insulation material capable of supporting loads while providing thermal protection.
Why Choose Calcium Silicate for Pressure Vessel Insulation?
Calcium silicate insulation is specified for high-temperature applications requiring structural strength to support jacketing, personnel traffic, or equipment loads. Its rigidity makes it ideal for flat surfaces, large vessels, and applications where insulation must maintain shape under mechanical stress. Calcium silicate is non-combustible and does not support mold growth.
Calcium Silicate Insulated Pressure Vessel Applications
Common applications include:
- High-temperature process vessels
- Boilers and steam equipment
- Industrial ovens and furnaces
- Power plant equipment
- Refinery vessels and piping

Calcium Silicate Insulated Pressure Vessel Frequently Asked Questions (FAQs)
What makes calcium silicate different from mineral wool?
Calcium silicate is a rigid, load-bearing insulation while mineral wool is flexible and fibrous. Calcium silicate can support personnel traffic, equipment loads, and heavy jacketing systems. It maintains structural integrity over time and does not settle or compress. Mineral wool offers better thermal performance but requires support systems for heavy loads.
Is calcium silicate suitable for outdoor installations?
Yes, calcium silicate performs well outdoors with proper jacketing. Its rigid structure resists damage from wind and physical impact. However, calcium silicate is absorbent and requires weatherproof jacketing to prevent moisture uptake. Proper vapor barriers and weather sealing are essential for outdoor service life.
What applications specifically require calcium silicate?
Calcium silicate is typically specified for high-temperature applications where insulation must bear loads (walkways, pipe supports), where rigid shape is required (large flat surfaces), and where fire resistance is critical. Its abuse resistance makes it suitable for industrial environments with potential for physical damage.
