CRN PRESSURE VESSELS

Both Canada and the United States use the ASME Section VIII code for pressure vessel design and construction but Canada has standard CSA B51 that further defines a Pressure Vessel.

Each province does its own registration and provides a CRN number which is put on the vessel nameplate. There are 13 provinces and territories, but to register across all of Canada, the “product” must be registered with 7 Organizations or Jurisdictions. The Atlantic Canada provinces and the northern territories have joined together to use one registration organization, ACI Central.

Saskatchewan is the only province that recognizes the internationally recognized National Board registration system (ASME) as an acceptable alternative to CRNs, although an additional Saskatchewan filing fee also has to be paid per vessel. Pressure vessels that are CRN registered can also be National Board Registered if desired. A design can be registered in more than one jurisdiction.

For pressure vessels manufactured outside of Canada for Canadian use, it must be both CRN registered and National Board registered.

BEPeterson designs and manufactures CRN pressure vessels. We assume “turn-key” responsibility to insure that your pressure vessel meets all ASME and CRN requirements for the province where the pressure vessel will be used. Single province CRN’s or multiple province and national registration for OEM distribution is provided by BEPeterson.
