Is Your Pressure Vessel up to Code? - Dixie Southern


Is Your Pressure Vessel up to Code?

May 10, 2016

Pressure vessel requirements vary state by state. Some states have a boiler law, but others do not. Florida boiler law, for example, is detailed in Florida Statute 554, “The Boiler Safety Act,” which sets minimum standards for construction, installation, operation, maintenance, and repairs for boilers.

Though not standardized nationwide, the most common state laws governing pressure vessels require adherence to the American Society of Mechanical Engineers (ASME) and/or the National Board Inspection Code (NBIC).
As a leader in custom steel fabrication, Dixie-Southern designs and fabricates pressure vessels that conform to your state’s exact requirements—keeping your employees and products safe, and protecting you from noncompliance fines. Today we’ll tell you what you need to know.

Common Requirements for Pressure Vessels

If you own and operate a pressure vessel at your business, it’s more than likely that it will need to meet these basic requirements:

  • Registered with the state boiler and pressure vessel department
  • If it operates between 15 psi and 3000 psi. it must be designed and constructed in accord with Section VIII of the ASME Boiler and Pressure Vessel Code, Rules for Construction of Pressure Vessels, Division 1.
  • Must have the manufacturer, serial number, the year built, and the maximum pressure capacity for specific temperatures, and any special capabilities clearly marked.
  • Have the vessel approved for installation along with the submission of drawings, specifications, and welding details. An authorized inspector must approve the welding and witness the testing.
  • Must be able to operate at levels below maximum allowable with pressure relieving devices.
  • Pressure vessels must be inspected periodically for corrosion and tested in accord with the NBIC Manual for Boiler and Pressure Vessel

Inspectors or American Petroleum Institute (API) 510, “Pressure Vessel Inspection Code.”
Plans to alter or repair pressure vessels must be approved by an authorized inspector, and the repairs themselves must be performed by test-qualified welders.
