Abstract
PURPOSE: To prevent the hydrogen absorption by titanium empolying a clad steel made of iron-nickel alloy containing a copper alloy and 8 to 30% of nickel in a multi-tube heat exchanger using titanium for the heat exchanger tube.
CONSTITUTION: Titanium absorbs hydrogen when a corrosion cell forms at a contact section between the carbon steel and titanium with infiltration of brine or steam. To prevent such a hydrogen absorption by titanium in the deaired brine at a high temperature exceeding 70°C, a iron-nickel alloy containing 8 to 30% of nickel is used in stead of the carbon steel. With such an arrangement, the potential in combination with titanium is held within such a level as to avoid the hydrogen absorption. Accordingly, a multi-tube heat exchanger may be produced using titanium for the heat exchanger tube 3 and a clad steel made of an iron-nickel alloy containing a copper alloy and 8 and 30% of nickel for the tube plate 4.
