  The LNG industry is currently in a boom stage. With the development of the world economy, the LNG industry is becoming a major source of global energy consumption. Governments are encouraging the development of the LNG industry to meet the growing energy needs of the domestic market. The future of the LNG industry is very bright and the future market prospects are very optimistic.


  Common LNG storage tanks are double-insulated, with a special wire mesh covering the outer layer and a closed vacuum structure inside, filled with insulated air to ensure temperature and pressure in the tank. In addition, the LNG tanks are equipped with efficient charging and cooling machines that quickly cool the LNG in the tank and ensure that the temperature in the tank is maintained at a constant level.

  LNG elastic felt, as one of the important components of cryothermal insulation system of LNG storage tank, is located between the inner tank wall plate and expanded perlite, and is used to absorb the side pressure of the expanded perlite inside the tank under various working conditions (pre-cooling contraction of the inner tank, hydraulic expansion of the LNG operation, expansion of the inner tank during empting and maintenance, etc.) in order to maintain the integrity of the tank and prevent the damage of the inner tank wall plate.

  Low temperature elastic felt is an important material for LNG (liquefied natural gas) storage and transportation. Its main functions are as follows: 1. Damping the fluctuations of condensed gas, making its transmission and storage process more stable and stable; 2. 2. Prevent pollutants inside the pipeline from entering the LNG; 3, protect the inner wall of the pipeline, prevent the external temperature is too high or too low to the damage of the pipeline; 4. Reduce heat loss and ensure the quality of LNG.
