Boiler Tube repairs - American Welding Society

10/10/2007 · To just weld a pinhole in a boiler seems pretty 'seat of the pants' for something as sophisticated as a boiler. take two flat pieces of steel of the same (or at least similar) composition and tensile strength than those of the boiler tube. The length could be, for example, 4 inches or 100 mm.

Best Practices For Expanding Water-Tube Boiler Tubes - …

Boiler expanders are designed with rolls sufficiently long to roll 1/4" to 3/8" beyond the sheet thickness. Boiler inspectors insist that tubes be rolled the full thickness plus a minimum of 3/16" beyond the sheet or drum thickness to a maximum 1/2". It's very common to use four or five different tools when repairing watertube boilers.
