Application area
Cryogenic Insulation
Piping and storage tanks for low-temperature and cryogenic services typically operate within a temperature range of -40°C to -192°C. In LNG projects and other cryogenic facilities, the storage and transportation of these media require specialized protection against heat leakage.
Currently, the most widely used cryogenic insulation materials include PUR/PIR, cellular glass, elastomeric rubber, and modified phenolic foam. These materials represent a significant improvement over previously used perlite, both in terms of performance and installation.
However, the introduction of aerogel cryogenic insulation constitutes a paradigm shift for the existing cryogenic insulation systems.

Challenges
> Traditional materials suffer from rapid performance degradation and high maintenance costs.
>Traditional materials have poor insulating properties, leading to major cooling loss and presenting major risks for LNG and other compressed gas during transportation and storage.
> Inadequate insulation performance in traditional materials readily causes condensation, resulting in pipeline corrosion.
> The insulation layer can easily become ineffective due to excessive condensation. While organic materials offer good water resistance, but cannot comply with fire safety requirements. -
Benefits of aerogel insulation materials
> With extremely low thermal conductivity and excellent insulation effect, aerogel blanket sharply reduces the thickness for insulation material and effectively cuts down the cooling lost, enabling intensive pipeline designs and layouts.
> Stable performance at ultralow temperature, even used at -200 Celsius, aerogel blanket still maintains flexibility and other properties without any cracks or breaking.
> It maintains excellent waterproof performance even at cryogenic temperatures, preventing condensation from penetrating to the metal pipe surface and thereby preventing pipeline corrosion.
> Easy for cutting and installing with low cost for routine maintenance.
