Abstract
A joint between a hot and unrefrigerated pipe (1) and a refrigerated pipe (2). The end of the unrefrigerated pipe is bifurcated in cross-section, leaving two sections joined at one end. The exterior section (6) is fastened tight to the refrigerated pipe (2). The interior section (5) extends into the refrigerated pipe leaving a radial and axial gap. The cylindrical space between the interior and the exterior section is full of heat insulation. There is a flexible component, an O ring (13) for instance, between, and resting tight against, the face of the refrigerated pipe and that of the interior section of the unrefrigerated pipe. The insulation comprises an axial series of layers (10, 11, & 12), each with a different heat conductivity.
