: : We have an HRSG , Nooter/Erisen Boiler. Water Tube. We are having numerous tube leaks, in our IP Economizer. Currently we have 4 tubes that are plugged. We have 8 flow circuits and 16 transverse sections.
: : Tube matewrial is SA-178A. The inside of the tubes are showing some corrossion, but not too severe given the age of the boiler; 13 years.
