What the R Stamp means for your engine
Code repairs you can hand to your inspector
Evans Welding and Fabrication holds a valid certificate of authorization from the National Board of Boiler and Pressure Vessel Inspectors to repair historical power boilers. The “R” stamp allows us to perform welded repairs and alterations under the pressure vessel code.
Earning it takes a written quality system that follows the National Board Inspection Code (NBIC). It spells out how every repair is controlled, documented and recorded. Our welders also pass demanding weld tests that meet ASME Section IX.
For you, that means a repair that comes with paperwork your state boiler inspector and your insurance company will recognize.
