Hot Insulation

Calsium Silicate Pipe Cover

Calcium Silicate Pipe Cover is a thermal insulation material in the form of a half-cylinder (half section), specifically designed to insulate and protect piping systems in industrial applications. It is made from calcium silicate with a microporous structure that provides excellent thermal insulation performance as well as high mechanical strength.

This material is widely used in high-temperature applications due to its ability to reduce heat loss, maintain energy efficiency, and provide protection against fire hazards and damage caused by prolonged exposure to extreme temperatures.

Characteristics & Advantages

• High Temperature Resistance – Capable of operating up to approximately 650°C (depending on grade)
• High Mechanical Strength – Resistant to cracking or damage during installation and operation
• Low Thermal Conductivity – Effectively reduces heat loss
• Non-Combustible – Enhances system safety by resisting fire
• Resistant to Pressure & Vibration – Suitable for heavy industrial environments
• Corrosion Resistance (CUI Resistance) – Helps reduce the risk of Corrosion Under Insulation
• Excellent Dimensional Stability – Minimal shrinkage or deformation at high temperatures
• Easy Installation – Half-section design simplifies pipe installation
