CRN is a Canadian Registration Number issued by each province or territory of Canada for the design and manufacture of boilers, pressure vessels and fittings to be shipped for use in Canada. It is important to note that each province and territories have unique application criteria for CRN.
Some fittings, piping and components are pre-approved for CRN, while others will require detailed calculations and/or testing to verify compliance. Certain design attributes may be accepted by some provinces or territories, but not by others. Further, some provinces and territories require a PE (Professional Engineer) stamp, but not all have this requirement.
One process is consistent; each province and territory requires the submission of the design to the CRN regulatory agency and the equipment must have a CRN number before it can ship and be placed in service.
How can manufacturers and processors plan for CRN for their tank and vessel projects? Start wth early planning and consider vessels as a long lead item. Determine design and shipping requirements at the onset of scope management discussions and allow several weeks, depending on project complexity, for the CRN number to be granted.
