🔍 Key Concepts

• Purpose of tube rolling in a boiler drum tube sheet (what does rolling actually do to the tube and the sheet?) • Relationship between rolling depth and the thickness of the drum tube sheet • How over-rolling vs. under-rolling affects tube strength, sealing, and risk of damage to the sheet

💭 Think About

• Think about what you want the joint to do before welding: create a tight mechanical seal without thinning or cutting the tube excessively. • If you roll too shallow or too deep relative to the sheet thickness, what could happen to the metal at the point of highest stress? • Which choice best balances getting a good seal and support while avoiding distortion or cracking of the tube sheet or tube?:

✅ Before You Answer

• Compare how each option affects the stress concentration in the tube and tube sheet. • Ask: Would this method risk weakening the tube or enlarging the tube hole in the drum tube sheet? • Verify which approach is most consistent with standard boiler practice to prevent leaks and maintain tube support.
