ASME Pressure Vessel Fabrication, Inspection & Testing

Jan 03, 2017

Since 1976, Dixie-Southern has manufactured ASME pressure vessels for customers across the country in many different industries, including water treatment, food processing, power generation, energy, and oil and gas. Our reputation as a leading custom steel fabricator was won by consistently meeting demanding schedules and quality requirements, and that’s thanks to our experienced fabricators and welders.

ASME Pressure Vessel Fabrication

Every ASME pressure vessel we design conforms to ASME Boiler and Pressure Code for Design, Section VIII. All materials used conform to ASME Boiler and Pressure Vessel Code for Materials, Section II.

ASME Pressure Vessels, Section VIII Division 1 – U stamp

  • Operating at pressures exceeding 15 psig, internal or external –
  • Have different requirements for numerous classes of materials as well as for fabrication methods, including welding, brazing and forging
  • May be fired or unfired


ASME Pressure Vessels, Section VIII Division 2 – U2 stamp

  • Vessels to be installed in a fixed location for a specific service –
  • Operation and maintenance control should be retained during the useful life of the vessel by the user who prepares or causes to be prepared the design specifications
  • Requirements for design, materials, and nondestructive examination are more rigorous than Division I ASME pressure vessels

We give our customers the opportunity to review all ASME pressure vessel designs before we begin procuring material. Once the design has been approved, we quickly begin fabrication. We perform many kinds of welding for ASME pressure vessels, including GTAW, FCAW, GMAW, SAW, and SMAW.

Experience Counts: ASME Pressure Vessel Testing and Inspection

Our engineers work closely with our expert drafters to ensure that every Dixie-Southern ASME pressure vessel meets industry codes and complies with regulations. If no custom testing has been requested by the customer, a certified inspector verifies the product’s overall integrity with non-destructive testing (NDT), applies a national board (NB) label, and registers it with the National Board of Boiler and Steel Pressure Vessel Inspectors prior to shipping.
