FIELD: cryogenic engineering.
SUBSTANCE: tank comprises vessel with heat insulation made of a polyurethane foam and casing. The vessel is provided with the additional layer made of a polyurethane foam. Between the layers of the polyurethane foam is a shock-absorbing spacer secured with the use of a sealing layer. The layers of the polyurethane foam are provided with compensation joints arranged with a spaced relation one with respect to the other both in the radial and axial directions. The joints are filled with a fiber heat insulation material and are sealed.
EFFECT: reduced heat loss and enhanced reliability.
