Abstract
A method for forming a lining on the internal faces of a vessel involves installing a granular composition into a gap formed between the internal faces of the vessel and a mandrel. The granular composition is dropped into the gap in the form of a single mass.
Claims50
A method for installing a substantially dry granular composition in the form of a single mass to form a layer on internal faces of a vessel comprising:
- installing said granular composition into a gap formed between a mandrel and the internal faces of said vessel, said installing including allowing said granular composition to drop into said gap in the form of a single mass such that as the granular composition drops into said gap it is restrained only by said mandrel and the internal faces of said vessel.
A method for installing a substantially dry granular composition in the form of a single mass to form a layer on internal faces of a vessel comprising:
- installing said granular composition into a gap formed between a mandrel and the internal faces of said vessel, said installing including allowing said granular composition to drop into said gap in the form of a single mass and at a pressure not equal to atmospheric pressure and in a gas other than air.
A method for installing a substantially dry granular composition in the form of a single mass to form a layer on internal faces of a vessel comprising:
- installing said granular composition into a gap formed between a mandrel and the internal faces of said vessel, said installing including allowing said granular composition to drop into said gap in the form of a single mass, and wherein an installing member comprising at least one valve is used to install said granular composition, wherein said installing member comprises at least one holding area around its perimeter, wherein said holding area holds said granular composition, and wherein said at least one valve corresponds to said at least one holding area and to said gap formed between said mandrel and said vessel, wherein said at least one valve may be opened or closed, and wherein when said at least one valve is opened, said granular composition is installed into said gap from said installing member.
A method for installing a substantially dry granular composition in the form of a single mass to form a layer on internal faces of a vessel comprising:
- installing said granular composition into a gap formed between a mandrel and the internal faces of said vessel, said installing including allowing said granular composition to drop into said gap in the form of a single mass, wherein an installing member is used to install said granular composition, wherein said installing member comprises at least one holding area around its perimeter, wherein said holding area holds said granular composition, and wherein said installing member comprises one or more deflectors, wherein said one or more deflectors aid flow and mixing of said granular composition.
