Abstract: A method of forming a thermally insulated composite article having an inner core surrounded by a cushioning layer and an outer shell. The core member, including at least one continuous inner surface defining a fluid passage therethrough, is either cast or formed from a block of erosion resistant high impact material. The inner surfaces of the core are then coated with a granulated or powdered material which is fused forming an impervious layer and the outer core surfaces are covered with a layer of refractory cushioning material. Finally a metal shell is applied over the cushioning layer to complete the composite article.
