摘要： A heat exchanger including a shell (12) for flow of a first fluid and a plurality of tubes (22) for flow of a second fluid in heat exchange relation therewith. A tubular member (40) is concentric with at least a portion of a tube (36) to define a space (44) between the tube and tubular member. The tubular member (40) includes at least one radially outwardly longitudinally extending projection portion (66) for effecting flexing of the tubular member radially outwardly so that a minimum clearance between the tube and the tubular member may be provided, and so that the tube (36) may be inserted in and removed from the tubular member (40) to provide greater accessibility for welding tubular members to tube sheets during assembly. Oxygen may be introduced into the space (44) between the tubular member (40) and tube (36), to combine with tritium which may diffuse through the tubular member wall to prevent diffusion of the tritium through the tube wall.
