Thermal Insulation Materials in Petrochemical & Refinery

The petrochemical industry relies heavily on thermal insulation and refractory materials to ensure safe and efficient operations in high-temperature and corrosive environments. These materials are crucial for:

• Process Vessels and Reactors: Maintaining desired reaction temperatures and protecting vessel walls from chemical attack.

• Piping Systems: Reducing heat loss and preventing thermal stress in pipelines carrying hot fluids.

• Furnaces and Heaters: Ensuring efficient combustion and heat transfer while protecting furnace structures.

• Storage Tanks: Regulating the temperature of stored materials and preventing excessive heat gain or loss.

• Waste Heat Recovery Systems: Maximizing energy efficiency by capturing and reusing waste heat.

Calcium Silicate Board and Pipe Sections:

Calcium silicate is a popular choice for insulation in petrochemical plants due to its:

• High-Temperature Resistance: Withstands temperatures up to 1100°C, suitable for many petrochemical processes.

• Low Thermal Conductivity: Minimizes heat transfer, ensuring efficient insulation and energy savings.

• Lightweight: Reduces the load on structures and simplifies installation.

• Excellent Dimensional Stability: Maintains its shape and properties at high temperatures.

• Resistance to Chemical Attack: Withstands exposure to many chemicals commonly found in petrochemical plants.

Calcium silicate is manufactured in board and pipe section forms, allowing for versatile applications:

• Board: Used to insulate flat surfaces like vessel walls, furnace casings, and storage tank roofs.

• Pipe sections: Pre-formed to fit around pipes, providing insulation for hot fluid transport.

These materials contribute to improved energy efficiency, reduced operating costs, and enhanced safety in petrochemical facilities. They help maintain stable process temperatures, protect equipment from thermal damage, and prevent personnel from exposure to excessive heat.

HCS-25 1100°C boards, NR-25 1000°C boards, NR 650 °C calcium silicate pipe section and NR-High density calcium silicate 1000°C rings are the suitable ideal materials for petrochemical thermal insulation applications.
