Pipes & Tanks Insulation


Insulating pipes and tanks in major industrial projects is crucial to maintain temperature stability, energy efficiency, and safety. Different insulation materials and techniques are used for hot and cold applications in various industries like LNG plants, power plants, petrochemical plants, oil refineries, fertilizer plants, and other industrial facilities such as cement and paper production plants. Here's an overview of the insulation materials and installation processes commonly used:

Insulation Materials:

Hot Insulation Materials:

  • Mineral Wool (Rockwool or Mineral Fiber): This material is widely used due to its excellent thermal properties and fire resistance.
  •  Calcium Silicate: Suitable for high-temperature applications and offers good thermal resistance and durability. 
  • Ceramic Fiber: Used for extremely high-temperature applications; provides lightweight insulation.

Cold Insulation Materials:

  • Polyurethane Foam: Offers high insulation value and is commonly used for pipes and equipment with complex shapes.
  • Polyisocyanurate Foam (PIR): Offers higher fire resistance compared to polyurethane foam.
  • Extruded Polystyrene (XPS): Used for low-temperature insulation applications.
  • Fiberglass Insulation: Suitable for both hot and cold applications, offering good thermal resistance.

Metal Jacketing:

Metal jacketing is used to protect the insulation material from mechanical damage, weather exposure, and other environmental factors. Common metals used for jacketing include aluminum and stainless steel. The jacketing is installed over the insulation material and secured with mechanical fasteners.
