LNG cryogenic storage and transportation systems place extremely high demands on insulation materials. Temperatures typically range from -160℃, requiring materials with stable thermal conductivity and structural toughness. Elastic felt, due to its soft fiber structure, low thermal conductivity, and stable compressive strength, is widely used in tanks, cryogenic pipelines, and other LNG installations.

Elastic felt maintains a certain degree of elasticity in cryogenic environments, resisting cracking, pulverization, or structural loosening, thus ensuring the continuous and effective operation of the insulation layer. Furthermore, its moderate density allows for tailored application to different equipment requirements, improving installation adaptability.

In practical applications, the appropriate thickness and number of layers must be selected based on the equipment's operating conditions to ensure stable insulation performance. Combining it with a metal outer sheath can enhance the overall system's resistance to wind erosion and compressive stress. With the continuous development of the LNG industry, the application prospects of cryogenic elastic felt will continue to expand.
