Abstract: The present invention relates to a tube for transporting fluids in seawater. The tube has a tubular body formed of an alloy selected from duplex stainless steel, superduplex stainless steel, a ferritic steel, a martensitic steel or a nickel superalloy and a layer configured to protect the tube from hydrogen induced stress cracking arranged on an outer surface of the tubular body. The layer is formed of an alloy having a copper content of 50-95 wt % and a nickel content of 5-50 wt %. The tube has a metallurgical bond, formed in the solid state, at an interface between the tubular body and the layer. The metallurgical bond is formed by a hot isostatic pressing process for a predetermined time at a predetermined pressure and a predetermined temperature. The present invention also relates to a method for manufacturing a tube. The present invention also relates to a subsea arrangement.

Abstract: The inventive concept relates to method for manufacturing a metal based component comprising at least one protrusion.

Abstract: The invention relates to a method for manufacturing a solid metal based component. The method comprising the steps of providing a plurality of metal based sheets; arranging the plurality of metal based sheets in a stack, 5 wherein the stack comprises a first metal based sheet, a last metal based sheet and at least one intermediate metal based sheet; perimetrically sealing at least a portion of the stack forming at least one cavity inside of the stack; removing gas from said at least one cavity, and subjecting the stack to a hot isostatic pressing process for a predetermined time at a predetermined 10 pressure and a predetermined temperature so that the plurality of metal based sheets of the stack bond metallurgically to each other to form a solid metal based component. The invention further relates to a single-piece metal based component.

Abstract: The inventive concept relates to a method for manufacturing a metal based frame comprising the steps of: providing a first element (202) comprising a first element inner enveloping wall (204) surrounding an interior volume; providing a second element (210) having a second element outer wall (212), a second element inner wall (213), and a third element (220) having a third element outer wall (222), a third element inner wall, wherein the second element inner wall (213) and the third element inner wall each surrounds a free space (215); arranging the second element (210) and the third element (220) in the interior volume (208) such that an intermediate space (230) having an access opening (232) is formed between the first element inner enveloping wall (204) and the second element outer wall (212) and the third element outer wall (222) in a predetermined pattern; arranging a plurality of pieces of a wrought material (250) in the intermediate space (230); providing a closing member (240) arranged such that it cov

Abstract: A method for coating a metal based component surface wherein said metal based component has an inner and/or outer surface portion that is to be coated, and which surface portion comprises a carbide forming composition. A cavity having one or more cavity walls, wherein said at least one inner and/or outer surface portion forms at least a portion of said one or more cavity walls is provided, and a portion of the cavity is filled with diamond powder. Thereafter gas is removed from the interface between said diamond powder and said at least one inner and/or outer surface portion, and the cavity is subjected to a hot pressing process for a predetermined time at a predetermined pressure and a predetermined temperature such that said diamond powder diffusion bonds to said at least one one inner and/or outer surface portion. Finally at least a part of said diamond powder is removed from said at least one cavity.

Abstract: The inventive concept relates to a method for manufacturing a metal based component (100, 200) having a cavity (103, 203). The method comprises the steps of: providing a plurality of individual segments (110, 210) corresponding to different portions of the metal based component; arranging the plurality of segments in a stack (120, 220) in such a way that the shape of the stack corresponds to the shape of the metal based component, and that a void (130, 230) is formed in the stack, wherein the shape of at least a portion of the void corresponds to the shape of the cavity; filling at least the first 10 portion of the void with an incompressible filler (140, 240); removing gas from the stack; subjecting the stack to a hot pressing process to form the metal based component comprising the cavity; removing at least a part of the incompressible filler from the metal based component.
