Detailed description of the invention
With reference to figure 1, present for the transport of LNG or the Fluid Sealing of holding vessel part and heat insulation wall construction.This wall comprises the pantostrat on multiple thickness direction being superimposed upon supporting structure 1.Such as, supporting construction 1 is the inner casing of the bivalve of ship.This wall construction comprises a class B insulation barrier 2, level Fluid Sealing barrier 3, major insulation barrier 4 and a main fluid seal barrier 5 successively.
As shown in Figure 4, this primary seal barrier 5 is produced with the structure of corrugated metal film, and this corrugated metal film produces together obtain by welding multiple rectangular metal plate 10.One metallic plate 10 is included in the parallel low ripple of what is called 11 of First Series on its inner surface what is called high ripple 12 parallel with a second series, and its respective direction is mutually perpendicular.10 edges of this metallic plate are parallel to ripple 11 and 12.Here term " height " and " low " have a relative meaning and mean that height that First Series ripple has is less than the height of second series ripple 12.At a cross part 13 between low ripple 11 and high ripple 12, this low ripple 11 is discontinuous, namely it is that this bends the top and the top be incident upon above described low ripple 11 that extend high ripple 12 by a bending (not shown) interrupted.This shape is sightless in the drawings.
Such as, this low ripple 11 has a height, and this is highly defined between the surface of this top and metallic plate 10, equals about 36 millimeters, and the width of the base of ripple 11 is greatly about 53 millimeters.Such as, this high ripple 12 has the height be defined between this top and plate 10 and is approximately 54.5 millimeters, and the width of the base of ripple 12 is greatly about 77 millimeters.
Such as, this metallic plate 10 is made by stainless steel or aluminium plate, thickness about 1.2 millimeters, and can by bending or pressing plastotype.Other metal or alloy and other thickness are also possible, because the thickness increasing metallic plate 10 can increase its cost and usually increase the rigidity of ripple.In the application of the Fluid Sealing film for cold fluid, need some flexibilities of metallic plate 10, thus make it possible to carry out thermal contraction when avoiding destruction sealing risk.
