Storage tank for cold liquids, and method for applying a thermal insulation system in such tank

摘要

A double containment storage tank, suitable for storing cold liquids, is provided with a non-metallic thermal protection system. The storage tank can include a first vapour-tight and gas-tight PU coating applied by spraying on the inner surface of the floor and walls of the tank; a first insulation PU foam layer arranged on the inner side of the first coating; a second liquid-tight PU coating applied in at least the bottom corner sections of the tank by spraying on the inner surface of the first foam layer; a second insulation PU foam layer arranged on the inner side of the second coating; and a third liquid-tight PU coating arranged by spraying on the inner side of the second foam layer.
