摘要： 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 at an interface between the tubular body and the layer. The metallurgical bond is formed by a hot 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.

摘要： The invention relates to a method for manufacturing a 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, 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 pressure and a predetermined temperature so that the plurality of metal based sheets of the stack bond metallurgically to each other.
The invention further relates to a single-piece metal based component.

摘要： 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 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 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.
