Isolation system gnl storage tanks having a secondary barrier welded construction method thereof

摘要

Isolation system storage tanks LNG having a welded construction method of the same secondary barrier. # Refers to an insulation system of storage tanks / LNG having the secondary barrier welded, which panels side insulation are fixed to a helmet using coupling means, a secondary barrier is formed integrally welding strakes, each of which is formed by processing a thin metal foil, panels main insulation panels and side insulation are stacked alternately so that the edges of the panels main insulation and the edges of panels side insulation are staggered, and panels main insulation adhere to the secondary barrier using adhesive agent, thus improving significantly the thermal insulation, tightness against LNG, and workability, and a method of building my Saint.
