Glass fiber resilient blanket
Special insulation material for LNG storage tank
Description
As an important structural component of cryothermal insulation system of LNG storage tank, the glass fiber resilient blanket insulation layer is located between the inner tank wall panel and expanded perlite,which is used to absorb the side pressure of expanded perlite in the inner tank under various working conditions(pre-cooling contraction of the inner tank,hydraulic expansion of LNG operation,expansion of the inner tank during empty-maintenance,etc.) to maintain the integrity on the storage tank. Prevent damage to inner tank siding.

1. Excellent Resilience:
The coefficient of resilience>0.44 has excellent resilience. In addition to absorbing the lateral pressure of the tank’s expanding perlite under various conditions,the elastic felt itself maintains its integrity.

2.Excellent fire resistance:
A1 grade non-combustible fireproof material, greatly improve the safety performance.

3.Excellent drying effect:
For example,when the moisture content of the material in the low temperature storage tank is too high,the replacement gas can not dry the insulation material in time, resulting in the tank body frost resulting in safety risks. The moisture content of glass fiber resilient blanket is as low as 0.4%,which has a very excellent drying effect to ensure the timely drying of the cryogenic insulation system of the LNG tank and ensure the stable operation of the system.

4.Excellent thermal insulation performance:
The thermal conductivity of glass fiber resilient blanket is as low as 0.040 W/m.k,with good thermal insulation effect, energy saving and environmental protection.

5.High tensile strength:
The fibers of resilient blanket are tightly bonded with each other, with strong gripping strength between fibers and tensile strength of no less than 18 KPa, so that the product has stronger tensile performance, and ensures the uniform distribution of fibers after installation and use of the product, without local thickness and insufficient strength.
