9 Ni 9 Ni IMPROVED WITH INSULATION STRUCTURE OF 9 NICKEL STEEL LIQUEFIED NATURAL GAS STORAGE TANK AND METHOD FOR CONSTRUCTING INSULATION OF 9 NICKEL STEEL LIQUEFIED NATURAL GAS STORAGE TANK USING THEREOF

摘要

The present invention relates to an insulating structure of a 9% Ni-steel liquefied natural gas storage tank and a method for filling insulation material of the 9% Ni-steel liquefied natural gas storage tank using the same. More specifically, the present invention relates to an insulating structure of a 9% Ni-steel liquefied natural gas storage tank which is improved in a structure to prevent the sinking of a ferrite insulation material by placing elastomeric insulation material that is contracted in a space portion of the 9% Ni-steel liquefied natural gas storage tank having the space portion between outer and inner parts thereof, and increasing the filling amount of the ferrite insulation material.
