ABSTRACT:
A process of attachment of at least one rib on a pipe with a thin wall which comprises cutting a hole in the rib that corresponds closely to the outer diameter of the pipe; locating the rib on the outer surface of the pipe; pressurizing the interior of the pipe with a pressure sufficient to force the outer surface of the pipe into close relationship with the inner contour of the rib during or shortly before reaching the soldering temperature; attaching the rib to the pipe by soldering; and selecting the materials for the rib and pipe so that the linear thermal expansion coefficients allow a smaller gap between the pipe and the rib during soldering than when the pipe and rib are at room temperature.
