Cryogenic Insulation
Safe solutions that minimize heat gain and boil-off rate in extreme conditions of -160°C and below.
Heat Gain, Boil-Off and Security Management in Extreme Cold
Cryogenic insulation is one of the areas of industrial insulation that requires the highest engineering precision. During the transportation and storage of LNG, LPG, liquid oxygen (LOX), liquid nitrogen (LIN) and similar low temperature fluids; Heat gain, boil-off, icing, condensation and mechanical stresses pose critical risks. Therefore, insulation in cryogenic systems is not only for energy efficiency; It is also essential for process safety, preventing product loss and maintaining equipment integrity.
What is Cryogenic Insulation?
It is a multi-layered and high-performance insulation system that is generally applied in equipment and lines operating between -50°C and -196°C. Aim:
- Minimizing heat gain
- Reducing the boil-off rate
- Prevent condensation & icing
- Reducing the risk of CUI (corrosion under insulation)
- Maintaining mechanical strength
Heat Gain and Boil-Off
Even the slightest heat input in cryogenic tanks and pipes can cause gasification of the fluid, pressure increase and safety valve activation.
Moisture Ingress and Icing
Air moisture seeping into the insulation and freezing causes volumetric expansion and disintegration of the insulation. The vapor barrier is vital.
Advantages of Cryogenic Insulation
1. Boil-Off Reduction
Heat gain decreases → Gasification is minimized.
2. Process Safety
The risk of pressure fluctuations and thermal shock is reduced.
3. Condensation & Icing Control
The surface temperature is kept stable.
4. Energy Efficiency
The load on cooling systems is reduced.
5. Equipment Life
Thermal stresses and CUI risk are reduced.
