These guys just finished installing 60 penetration seals (a full Alstom HRSG) which replaced the OEM “Korema Kompensatorenwerk” silicone & fiberglass expansion joints. All of the welded flange-studs on the front module (HPSH) had corroded and rusted, many had broken off. It was a gnarly job crawling around beneath the structural steel and welding them back together, but Steam Generation Corp was up to the task, and they’ve got the bruises to show it!
