Title: Insulated tank or tanker for liquefied gas - lined with thin membranes temporarily united during handling, bending and assembly
IPC: B21D51/24
Filed: 1974-10-15
Abstract: A low temp. reservoir for liquefied gas, comprises a rigid, outer container, e.g. the twin hull of a marine tanker, lined with a layer of compression-resistant thermal insulating material which is covered on the inside face by a pair of membranes i.e. a main, inner membrane which retains the liq. contents and an outer, standby membrane which prevents leakage if the first membrane fails. The two membranes are superimposed as flat sheets and secured temporarily together with a thermoplastic adhesive to be formed simultaneously to the shape required in the completed reservoir; after final assembly, the reservoir is charged with liquefied gas which lowers the temp. of the thermoplastic below that at which its adhesive properties are effective and the two membranes become separate as required in the final construction. Temporary combination of the two membranes greatly facilitates the handling, forming and assembly of the membranes with reduced danger of damage to a membrane which is delicate by virtue of its enormous ratio of area to thickness.
