Dual Laminate Clo2 Bleach Tower Upflow Tube, 2004 11th International Symposium on Corrosion in the Pulp and Paper Industry
The first ECTFE/RTP dual laminate D-Stage upflow tube was installed in fall of 1998. The mill was
able to improve their bleaching operation through elevated temperatures and throughput. In July of
2001 the tube was available for a brief inspection of the interior through the manways. Finally in
October 2003 a thorough interior inspection was performed. The installation costs, inspection results,
and projected life will be discussed. This is a follow up of the information presented during the 10th
International Symposium on Corrosion in Pulp and Paper Industry.
