ABSTRACT:
Method of making a heat-insulation-lined tank for low temperature liquids comprising a foamed insulation layer secured to the inner wall surface of the tank to be insulated, a plurality of wires in layers assembled crosswise in a netlike fashion and embedded in the insulation, and a liquidtight wall that covers the inner surface of the insulation, the spacings of the wires in netlike layers and of the layers themselves being made narrower on the low-temperature side or with the approach to the innermost layer of the lining. The tank has no possibility of cracking in the insulation layer due to thermal strains on exposure to low temperatures. A method of easily and satisfactorily manufacturing such an insulation-lined tank is also provided.
