Abstract
Abstract A distensible vessel, reduced in diameter by means of folds in its sidewall, is passed through a bore into a cavity and is expanded to size by internal pressure. The interior of the vessel is then reinforced by building up a suitably thick deposit of material applied to the walls in an adherent spray by means of an arc-spray gun arranged to traverse the interior of the vessel.
