Design registration for used/re-rated boilers

Boilers are registered in accordance with CSA B51 ‘Boiler, Pressure Vessel and Pressure Piping Code’. The standards governing the design and construction of boilers and pressure vessels are the ASME Boiler and Pressure Vessel Codes except as otherwise detailed in CSA B51 or the regulation.

A used boiler or pressure vessel must be registered before it is installed. If an in-service boiler, pressure vessel, or other pressure retaining equipment is to be altered or re-rated, the alteration and the revised design must be registered.

To register a design:

  1. Submit a completed boilers and pressure vessels repair and alteration report.
  2. Provide documentation to verify that the design conforms to the applicable code/requirement. Refer to a checklist here.
  3. For more than one design, please complete a separate application and collate documents by design.
  4. Only one set of drawings, calculations and application form is required for each design.
  5. Submit paper copy of the application, by mail or in person, to our Vancouver office. Mark the envelope - Attn: Engineering Design Registration.

Note: Incomplete application packages will not be processed.

Design registration process followed by Technical Safety BC

  1. The design registration submission will be reviewed to verify that all requirements have been met.
  2. Upon satisfactory review, the vessel design shall be assigned a Canadian Registration Number (CRN).
  3. A registration letter indicating the CRN, date of registration, manufacturer’s name, description of the vessel, drawing numbers, conditions and any other pertinent information will be sent to the applicant.
  4. A separate invoice will be forwarded for the fee.
  5. The average time for completing ​​​​​​the design registration process is 20 to 30 business days, upon receiving a completed application.

No other documents will be stamped or returned to the applicant.

Next Steps

    Step 1: Installation permit

    A permit is required to install and operate a boiler. Refer here for information on obtaining a boiler installation permit

    Step 2: Inspection

    Following the registration acceptance, the vessel installation and its piping shall be inspected and hydrostatically tested to a Safety Officer’s satisfaction before being placed in service. Refer to boiler inspections for more details.

    Step 3: Operating permit

    Obtain an operating permit that allows the operation and maintenance of a regulated product or equipment. For details on how to get an operating permit, see here.
