When your boiler is open for inspection, the fireside tells a story—if you know what you’re looking at. Here’s exactly what to check and why it matters. Jude walks through a fire tube boiler open for a Boiler University 301 class, covering welded tube ends, beaded tube ends, flared tube ends, what inspectors look for when peering through tubes, and how to identify cracking and distortion in the Morrison tube and tube sheet. Missing signs of thermal stress, oxygen pitting, tube movement, or furnace cracking during an inspection can turn a minor repair into a catastrophic failure—and a very expensive one. Safety notice: Always consult experts for complex repairs.
