Analysis of the application value of aerogel insulation felt in cryogenic pipelines
2025-12-09       Source:

Aerogel materials, due to their ultra-low thermal conductivity, are known as "super insulation materials of the era," with particularly significant advantages in low-temperature pipeline insulation. This article will describe the application, performance, and usage specifications of aerogel insulation felt.


I. Core Performance of Aerogel Insulation Felt

1. Extremely Low Thermal Conductivity: Conventional materials typically have a thermal conductivity of around 0.030 W/(m·K), while aerogel can reach as low as 0.015–0.020 W/(m·K), significantly improving insulation efficiency.

2. High Flexibility and Good Construction Adaptability: Suitable for complex structures such as elbows and flanges, reducing the risk of cold bridging caused by splicing gaps.

3. Excellent Moisture Resistance: Hydrophobic properties prevent the insulation layer from absorbing water and failing.

4. Achieves Insulation Effectiveness with Thinner Layers: Suitable for space-sensitive pipeline areas.


II. Application Areas: LNG cryogenic pipelines, chemical refrigeration pipelines, cold storage refrigeration equipment, cryogenic storage tank exterior walls, marine LNG systems.

III. Installation Method:

1. Select aerogel insulation felt of appropriate thickness.

2. Wrap or cover the pipeline and secure with straps.

3. Add an outer layer of aluminum sheet or color steel plate as needed.

4. Overlap and seal joints to prevent cold bridging.

IV. Precautions:

Avoid excessive stretching, which can affect insulation performance.

Seal cut edges promptly.

Select different types of aerogel felt according to temperature.

V. Summary: Aerogel insulation felt, with its excellent thermal properties, plays an important role in cryogenic pipeline insulation, significantly reducing energy consumption and improving system stability.
