Abstract

For reasons of economy and weight reduction, it sometimes is desirable to employ dissimilar metals in the construction of liquefied air converters, dewar vessels and tanks, coldboxes, and related cryogenic equipment. A typical item of such equipment may be comprised of an inner aluminum vessel which is suspended in and insulated from an outer shell of carbon steel (Fig. 1). Piping from the atmosphere, through the outer shell and adjacent annular space, and connected to the inner aluminum vessel usually is of a ferrous metal—stainless steel, more often than not—which has a lower heat conductivity than aluminum. Achieving a sound, leak-tight connection between these dissimilar metals is mandatory. It is also extremely difficult [1].
