Sweco Fab, Inc., our subsidiary, holds the National Board R-Stamp which enables us to do repairs and alterations on pressure vessels, boilers, and pressure-retaining items. Sweco acquired the National Board R-stamp in 2007. The R-Stamp requires maintaining high standards in materials, systems, and procedures and is issued by the National Board of Boiler and Pressure Vessel Inspectors.
