Membrane container construction for storing low-temperature liquified gas
Abstract
Abstract A container or carrier for storing a low-temperature liquified gas in which a thin, metallic, film or membrane fluid-containing inner vessel composed of a bottom wall, side walls and a top having a central opening has a flexible bulge developed on the top in the area of juncture of the top and side walls and this bulge straightens in cross section for compensating for temperature decreases and loading for the inner vessel with a liquified gas. The internal pressure of the inner vessel is supported by a rigid, outer vessel in which a heat-insulating layer of compression-resistant material is installed. The strength of the inner vessel is maintained by the compensating deformations and at the same time leakage of liquid is prevented. Pipes lead into the inner vessel through a trunk mounted on a top wall structure of the outer vessel.
