The tube includes a first portion projecting from the flange and through the through-bore and an opposite second portion projecting outward from the flange. The flange is in contact with the wall and the first portion includes an outer surface having a contour configured to produce sealing friction between the lip and the outer surface.

A storage vessel for an extremely low temperature material for reducing a vaporization rate by forming a plating layer at an outer surface of a discharge pipe thereof is provided. The storage vessel for an extremely low temperature material includes an inner container configured to store an extremely low temperature material of a liquefied state through a supply pipe in an inner receiving space; an outer container installed at a separated space at the outside of the inner container and having a vacuum port configured to enable the separated space to be a vacuum state; and a heat insulating member installed in a vacuum region between the inner container and the outer container to block a heat from being transferred to the inner container, wherein a discharge pipe connected to an outlet of the inner container and configured to vaporize and discharge an extremely low temperature material is disposed between the inner container and the outer container, and at an outer surface of the discharge pipe, a thermally conductive layer coated with a highly conductive material having high thermal conductivity is formed. By a such a configuration, a heat applied to an outer container can be effectively blocked from being transferred to an inner container for storing an extremely low temperature material, and by reducing a vaporization rate of the extremely low temperature material by increasing a heat transfer area of a discharge pipe, a loss rate according to vaporization of the extremely low temperature material can be reduced and a separate cheap auxiliary extremely low temperature material in addition to the extremely low temperature material can be subsidiarily used for fuel or industrial use.

A Sealed and thermally insulated tank has a tank wall on a carrier structure. The tank wall has an insulating barrier, sealed barrier and an anchoring member. The sealed barrier has a first undulating metal membrane and a second undulating metal membrane which are located at one side and the other of the anchoring member, along an assembly edge which is oriented parallel with a longitudinal direction of the anchoring member.
