Abstract
The present invention relates to a pipe assembly for conveying fumes in steel boilers provided with condensate quick evaporating means, characterized in that it comprises an inner pipe (2) and an outer pipe (3) which define a closed gap (4) therebetween. The main feature of the invention is that between the inner pipe (3) and outer pipe (4) are provided contacting lines extending according to parallel lines which are either helicoidal or not.
