Abstract

Alternative composite tubes to the conventional co-extruded 304L stainless steel/carbon steel composite tubes have been installed in several North American kraft recovery boilers in an attempt to resolve a cracking problem. This paper documents the performance experience of these alternative materials to date, in terms of reported cracking and corrosion incidents. Improvements have been made, but none of the alternative composite tubes represent a universal solution.
