Pipe In Pipe Insulation

The insulation of pipeline (PIPE-IN-PIPE) is done to preserve the temperature inside the line. The insulated pipes can be vertical or horizontal stretched all over the plant carrying various liquids.

For void free insulation and to avoid sweating over the surfaces proper insulation is required. Proper temperature can be maintained with minimum heat loss through proper insulation.

Insulation properties of Polyurethane Foam are much better than other insulating material hence it is preferred over other insulating materials.

The density of Polyurethane foam insulation is maintained around 40kg/m3.

Higher densities are also achieved as per the requirement of the customer.

PIR can also be used as an insulating material.

Advantages with In-situ foaming in Pipe lines:

• The risk for voids in the insulation is eliminated by the IN-SITU method.
• No joints in the foam.
• Homogeneous insulation.
• Increased insulation efficiency.
• Increased tightness.
• Non-corrosive and watertight cladding.
• Complete bonding to all surfaces.
• No penetration or space for accumulation of moisture.
• Excellent corrosion protection.
• Good fire fighting properties.
