Abstract
A pipe-shaped protective cover for a gun barrel mounted over at least a portion of the outer periphery of the gun barrel. The protective cover includes a first-insulating layer joined to the outer surface of the gun barrel; a second heat-conducting layer mounted on said first layer; and at least one additional heat-insulating layer followed by at least one additional heat conducting layer which are mounted in that order on the second aforementioned layer. The invention envisages a firm mounting of the protective cover on the gun barrel without the formation of intermediate air gaps between the cover and the gun barrel.
