IMPROVEMENT FOR LEAKTIGHT AND THERMALLY INSULATING TANK INTEGRATED INTO A CARRIER STRUCTURE

摘要

The tank has a primary sealing barrier (10), a secondary sealing barrier (5) and a thermal insulation barrier, where each barrier includes a rectangular parallelepiped module provided with a plywood plate (3) covered by a thermal insulation layer (4). The layer is covered by the secondary barrier on which another thermal insulation layer (6) i.e. T-shaped thermal insulation layer, is arranged. Another plywood plate (7) is constituted of two walls (8, 9), where the first wall supports the primary barrier and the second wall. A damping layer (11) is arranged between the walls. The walls are made of a fir plywood or composite material.
