Vessels

  • Vessels classified as ASME pressure vessels must be designed and calculated to the ASME code. Vessel or Fitting?
  • All ASME pressure vessels must be stamped with the appropriate ASME code mark and be registered with the National Board. CSA B51 4.10.1.2
  • Most provinces require a Professional Engineers (P. Eng) stamp on vessel drawings and calculations. A Professional Engineers stamp from anywhere in North America is accepted in most provinces. Ontario is the only province that states it must be an Ontario P. Eng.
  • Once a vessel is registered it can be built as many times as required in the registered province until the design is changed or an ASME code change makes the design invalid. There is no specific expiration date. CSA B51 4.1.2
