Issues regarding elastic felts in large LNG storage tanks
Thread Content
Are there any **standards or specification sheets** for the elastic felt in the annular space of large LNG storage tanks? ? ? In particular, data such as thermal conductivity and density are needed. Thank you~~ It’s best to use **standard**~~
Specific gravity: 0.016, thermal conductivity: less than 0.04, water content: 0.05 (by weight), K value greater than 0.44, strength: 6.1 KPA
Thank you~~~ By the way, what is that K? Coefficient of linear expansion, right? . . . .
K is the rebound factor; there are no established standards in China. Refer to ASTM C553-08 \"Standard Specification for Mineral Fiber Blanket Thermal Insulation for Commercial and Industrial Applications.\" Currently, most elastic felts are imported, such as those from ANCO/QUIETFLEX in the United States. Beijing Jin Haiyan, the most famous one in China, has poor resilience. It is mainly used for insulation in ceilings.
