• Is CRN (Canadian Registration Number) training from Cammar Corp. available ?

    Cammar Corporation can provide customized training for your staff, in relation to CRN registration and topics listed here, or others. We have the experience to prepare and deliver it.

    Training would typically occur over one or two days for select topics, to audiences of five or more persons that belong to your organization. There’s lots of information to consider and understand:

    1. Regulations,
    2. Adopted codes,
    3. Referenced standards,
    4. The Canadian Registration Number process (CRN registration), and
    5. Registration harmonization issues.

    For more details on training please our Canadian Registration Number (CRN) Training page.

  • Why are CRN Numbers (Canadian Registration Numbers) required?

    Canadian Registration Numbers (CRN numbers) identify unique pressure equipment designs for use in Canada, and must meet requirements.  Each design concept has a unique number.  One Canadian Registration Number can represent millions of individual items, each with a different serial number, that all conform to the CRN design.

    Canadian provincial regulatory authorities have cooperated to help ensure CRN numbers are tracked nationwide, and identifiable across provincial boundaries.  CRN numbers are required to be stamped on equipment or, in the case of very small fittings, trackable with other identification markings.

    CSA B51, the Canadian “Boiler, Pressure Vessel, and Pressure Piping Code”, describes the required rules of CRN use in detail.  Part 1, Clause 4 specifies that pressure fittings, pressure vessels, and boilers are assigned CRN numbers with the acceptance of regulatory authorities in provinces where the equipment is to be used.

    Vessel and boiler CRN numbers never start with a “0”.  Fitting CRN numbers always do. 

    All CRN numbers have a decimal point that follows the prefix assigned by the regulatory authority.

    For fittings, the letter following the “0” in the prefix corresponds to CSA B51 Table 1, and is used by regulatory authorities at their discretion to categorize the fitting according to type:

    1. Pipe fittings
    2. Flanges line
    3. Valves
    4. Flexible connections
    5. Strainers, filters, separators, traps
    6. Instrumentation
    7. Over pressure protection devices
    8. Items not in categories A to G

    Subsequent characters in the prefix that precede the decimal, are sequentially assigned by the regulatory authority.  For some fitting categories, five digits follow the letter noted above that precede the decimal.  For vessels, an alphanumeric (unless the registration is really old) and four digital characters precede the decimal. Following the decimal, the geographical region in which the design was first registered is identified with a character listed in Clause 4.3.2.:

    1     British Columbia
    2     Alberta
    3     Saskatchewan
    4     Manitoba
    5     Ontario
    6     Quebec
    7     New Brunswick
    8     Nova Scotia
    9     Prince Edward Island
    O     Newfoundland

    Y     Yukon

    The prefix, decimal, and character after the decimal identifies a unique design. 

    To indicate all of Canada, the letter “C” is subsequently used.  To indicate all regions in Canada which require registration, the “CL” is used.

    Subsequent digits identify other regions in which the design has been registered, in no particular order.

    Here are some examples of CRN numbers:

    1. B1234.256 pressure vessel design initially registered in Alberta, and also registered in Quebec and Ontario
    2. B1234.265 same CRN number as noted in 1 above despite reversal of “65”
    3. B1234.465 pressure vessel design different from items 1 and 2, and registered first in Manitoba
    4. 0B1234.265 flange design registered first in Alberta
    5. 0B1234.165 flange design different from that identified in item 4, and registered first in British Columbia
    6. 0B1234.2C flange design as noted in item 4, but registered in all Canadian regions
    7. 0B1234.2CL flange design as noted in item 4 above, but registered in all Canadian regions except those where registration is not required

  • What is pressure equipment in Canada?

    Canadian jurisdictions have enacted laws to protect the public where there is danger.  And pressure equipment is potentially extremely dangerous.  Even a small air receiver, with an internal pressure of just 230 psig, has the explosive energy of about 1 lb of dynamite.

    It’s defined somewhat differently across Canada, but Alberta has some pressure equipment definitions that are good benchmarks to consider.  The most common types of pressure equipment are classified as:

    • boilers,
    • pressure vessels,
    • pressure fittings, and
    • pressure piping systems.

    Though there are some exceptions, 15 psig (101kPag) is frequently the threshold at which the provisions of legislation kick in.  But danger exists at lower thresholds too.

    Consider ordinary, improperly used oil drums.  With a diameter of about 22.5 inches, an oil drum pressurized with air to just 10 psig would exert an internal force in the order of 4000 lbs on it’s flat end.  Dangerous indeed.

    What is an “expansible fluid”?  It means “((i) a vapour or gaseous fluid, or (ii) a liquid under pressure and at a temperature at which the liquid changes to a gas or vapour when the pressure is reduced to atmospheric pressure or when the temperature is increased to ambient temperature.” (AR 49/2006 1(1)(l))

    The term “boiler” means “a vessel in which steam or other vapour may be generated under pressure or in which a liquid may be put under pressure by the direct application of a heat source.”  (AR 49/2006 1(1)(f)) The term “pressure vessel” means “a vessel used for containing, storing, distributing, processing or otherwise handling an expansible fluid under pressure.” (AR 49/2006 1(1)(cc))

    Canadian jurisdictions have enacted laws to protect the public where  there is danger. But danger exists at lower thresholds too. The term “fitting” means “a valve, gauge, regulating or controlling  device, flange, pipe fitting or any other appurtenance that is attached to, or forms part of, a boiler, pressure vessel, or fired-heater pressure coil, thermal liquid heating system or pressure piping system.” (AR 49/2006 1(1)(n))

    The term “pressure piping system” means “pipes, tubes, conduits, fittings, gaskets, bolting and other components that make up a system for the conveyance of an expansible fluid under pressure and may also control the flow of that fluid.” (AR 49/2006 1(1)(aa)) All pressure equipment, not exempted from registration requirements, needs to be registered with a CRN before it can be legally operated in Canada. Why are there CRN requirements?

    It’s about public safety.  Call Cammar Corporation for more information about the CRN registration process.

  • How can Cammar Corp. help get a CRN (Canadian Registration Number)

    Whether it is a fitting, pressure vessel, boiler, or piping system that you want to get CRN registration for, Cammar Corporation can help with the design and evaluation so it complies with the governing adopted codes, standards, and regulations.  In other words, it needs to meet CRN requirements.

    Remember, unless a pressure equipment design is exempt from legislation requirements, it needs to be properly registered with a CRN (Canadian Registration Number) before it can be legally operated.  And to get it registered, it needs to comply with the related regulations and meet CRN requirements.  We can help you do this.
