    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.
