Southern Tank, Inc., is the only facility in the area to hold all three of the following certificates:  National Board R Stamp, ASME U Stamp and registered with the DOT/FMCSA. 

National Board R Stamp Certification

The R Stamp is an endorsement on loan from The National Board of Boiler and Pressure Vessel Inspectors which allows us to perform repairs and alterations to a variety of non-fired pressure tanks and vessels. 

ASME U Stamp Certification

The American Society of Mechanical Engineers (ASME) is a professional organization that focuses on technical, education and research issues in the engineering and technology community. ASME develops and maintains internationally recognized industrial and manufacturing codes and standards that enhance public safety.

ASME has accredited companies in the pressure vessel industry to certify that their products, services and quality system comply with the ASME Boiler and Pressure Vessel Code. This acceptance and certification is symbolized by the “U Stamp” for pressure vessels.

DOT/FMCSA Registration

The Department of Transportation and Federal Motor Carrier Safety Administration Registration helps ensure that we are compliant and up to date on all required practices and standards. 

The American Welding Society

The American Welding Society was founded to advance the science, technology and application of welding and allied processes including joining, brazring, soldering, cutting and thermal spray.
