Application of Aerogel Insulation Blanket on Low-Temperature Pipelines
Aerogel insulation blankets can provide optimal cooling effects and energy-saving economic value at temperatures as low as -200°C. In the petrochemical industry, Aerogel insulation blankets are frequently used in low-temperature pipelines (generally referring to pipelines with operating temperatures below -20°C).
The measure of covering the exterior of low-temperature pipelines with insulation materials to reduce the conduction of external heat into the pipeline and to maintains its surface temperature above the dew point, thus preventing condensation on the outer surface is called cold insulation. The insulating material applied on the exterior of the pipeline is usually referred to as cold insulation material.
Selecting suitable cold insulation materials is essential for improving cold insulation efficiency, ensuring the quality of the medium at the outlet, and promoting energy conservation and environmental protection.
Traditional Cold Insulation Materials
At present, commonly used cold insulation materials mainly include polyurethane, rubber -plastic, rock wool, etc. Compared with the previously used perlite materials, these materials have been greatly improved in terms of performance and construction. However, the emergence of aerogel cold insulation materials is a qualitative change for the existing cryogenic cold insulation system.
Current Status of Traditional Insulation Materials:
- Traditional insulation materials experience rapid decay in insulation performance, leading to high maintenance costs.
- Traditional insulation materials have poor cold insulation effects, resulting in significant loss of cooling capacity.
- Traditional insulation materials have a large wrapping thickness, which brings many inconveniences to the design of densely arranged pipelines. Pipelines are susceptible to corrosion from condensed water due to the poor cold insulation effect (CUI).
- Cold insulation layers easily lose their effectiveness due to excessive condensation. Organic materials have excellent waterproof properties but cannot meet fire protection requirements.
Anchor Tech Aerogel Insulation Blanket
Anchor Tech Aerogel Insulation Blanket is a flexible cooling insulation blanket made by advanced nano-composite technology, combining nano-silica aerogel with inorganic materials.
Product Advantages:
1.It exhibits outstanding cooling insulation performance with an extremely low thermal conductivity, providing optimal cooling effects and energy-saving economic value even at temperatures as low as -200°C.
2. The aerogel insulation blanket has superior fire resistance and hydrophobic properties, effectively inhibiting water from seeping into the surface of the metal pipeline, preventing pipeline corrosion (CUI), and avoiding a decrease in cooling insulation efficiency due to water infiltration.
3. The aerogel insulation blanket is 75% thinner in thickness compared to similar products, allowing for quicker and easier installation of this cooling insulation material, saving both time and expenses.
4. The material is easy to cut, facilitating convenient construction. It is safe, environmentally friendly, non-toxic, and has a long service life.
Application Scenarios:
Anchor Tech aerogel insulation blanket can significantly reduce cold losses and boil-off gas (BOG) losses. It is suitable for deep cryogenic pipelines equipment, medium and low-temperature pipelines, cold air fans/exhaust pipes, etc., such as LNG storage and transportation, liquid nitrogen and liquid oxygen storage equipment or transport pipelines, etc.
Application Case:
There were two DN100 chilled water pipes with ineffective insulation and leakage along the passage to the corner near the A-end control room of Tianhe Passenger Station on Line 3 of Guangzhou Metro. The total length is approximately 40 meters. We replaced and renovated them with the aerogel insulation blanket to solve the leakage issue and ensure operational safety.
High-quality cooling insulation materials not only reduce energy consumption and minimize cooling capacity loss but also provide a guarantee for safe production and better benefits for enterprises. Anchor Tech’s aerogel insulation blanket, with its excellent cooling insulation performance, flame resistance, hydrophobicity, ease of cutting, and long service life, is the ideal choice for customers in the field of deep cryogenic field who seek better cooling insulation effects and lower energy consumption.
