New, used, or re-rated boilers, unfired pressure vessels, and heat exchangers

Applicable codes

Boilers and pressure equipment, as defined in the Safety Standards Act and Regulations require design registration in accordance to 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 BSA B51 or the regulation.
 

To register a design

  1. Log in to our online Design Registration Portal. See How to Register for more details on how to create an account. 
  2. Select & complete applicable webform
  3. Upload and attach all supporting engineering documentation and acknowledge your professional declaration.  The professional declaration certifies that the submitted design is safe for construction and use, complies to the standards identified in this application, under the direct supervision and/or been reviewed directly by a qualified professional, and the skill and experience necessary to design and evaluate compliance to the identified standards were applied, to the best of the professional’s knowledge

Refer to the following checklists to preview the engineering documentation requirements

Additional considerations

Buried pressure vessels

Designs of pressure vessels to be buried underground must satisfy conditions of the environment it will be buried in by demonstrating that the vessel can safely withstand external loading imposed by the material, structures, and activity above and around the vessel. Learn more

Boilers and pressure vessels without full ASME Boiler and Pressure Vessel Code compliance

Constructed outside of Canada or the USA, manufacturers can submit documentation and evidence that the quality control system and procedures are equivalent to the appropriate ASME Sections (Section I for power boilers, Section IV for heating boilers, Section VIII for pressure vessels). Learn more 

Pneumatic Testing

Pneumatic testing must be included in submissions if the calculated stored energy of a compressed gas is >1677 kJ. All content must be reviewed and authenticated by a professional engineer and include calculations, spacing, and an assessment that discloses and mitigates hazards (ie. FMEA, HAZID, HAZOP, Fault Tree, or Bow Tie Analysis). Learn More

Pressure Piping

Pressure piping systems are a series of piping, and pressure components that convey an expansible fluid or non-expansible fluid between two points. These systems are regulated by Technical Safety BC and require a design registration, under specific requirements.
 

Applicable codes

The following pressure piping systems are recognized design codes for pressure piping:  

  • ASME B31.1 – Power Piping Code
  • ASME B31.3 – Process Piping Code
  • ASME B31.5 – Refrigeration Piping and Heat Transfer
  • ASME B31.9 – Building Services Piping
  • CSA B51 Boiler, Pressure Vessel, and Pressure Piping Code

The following requirements define pressure piping that require design registration.  Please note, Technical Safety BC is still the Authority Having Jurisdiction on all piping that meets the latest edition of CSA B51.  Pressure piping NPS 3 or smaller do not require design registration, however, the system must comply with all regulation and code requirements

  • Non-expansible fluids (ie. non-compressible), 1100 kPag (159 psig) and the operating temperature exceeds 121⁰ C (49°F), and is > NPS 3, then it requires design registration
  • Expansible fluids greater than 103 kPag (15psig), then it requires design registration.
     

To register a design

  1. Log in to our online Design Registration Portal.  See How to Register for more details on how to create an account. 
  2. Select & complete applicable webform
  3. Upload and attach all supporting documentation. Refer to the Pressure piping checklist for more details on requirements.
  4. Design registration is simply the beginning of the installation process.  Please refer to  Directive: Inspection requirements for piping systems and piping components for next steps.
     

Additional considerations

Operating conditions

It is the responsibility of the piping designer to understand the intended operating conditions of the range of design pressures, operating temperatures and the environment where the piping will be installed.  

The qualified professional must consider these temperature changes to adequately capture the piping system’s flexibility.

Oil and gas piping requirements

Oil and gas piping requires registration if the pressure piping meets the requirements of CSA B51. Learn more.

Pneumatic Testing

Pneumatic testing must be included in submissions if the calculated stored energy of a compressed gas is >1677 kJ. All content must be reviewed and authenticated by a professional engineer and include calculations, spacing, and an assessment that discloses and mitigates hazards (ie. FMEA, HAZID, HAZOP, Fault Tree, or Bow Tie Analysis). Learn More.

Pressure Fittings

Applicable codes

Pressure fittings as defined in the Safety Standards Act and Safety Regulations, require design registration in accordance to Clause 4.2 of CSA B51, "Boiler, Pressure Vessel and Pressure Piping Code."

The following pressure fittings are exempt from design registration:

  • Pressure piping external to a boiler proper in a low pressure, low temperature fluid plant that operates at a working pressure of 206 kPa or less, and a temperature of 100 ⁰ C or less; or
  • Pressure piping operating at 103 kPa or less, with a pressure relief valve set at 103 kPa or less.
  • Pressure piping NPS3 or smaller  (however, the system must comply with all regulation and code requirements).

  2. Select & complete applicable webform
  3. Upload and attach all supporting documentation. Refer to this Pressure fittings checklist for more details on requirements.

Special Message for Pressure Fittings Statutory Declarations 

We understand there may be difficulties obtaining a public notary or Commissioner of Oaths authentication during COVID-19 restrictions. Technical Safety BC does not require an original copy of the notarized form, but is accepting scanned and electronic signed forms. If you are unable to obtain a notarization electronically, please clearly indicate this on the Statutory Declaration form in lieu of the notarization signature while continuing to have the form signed by the manufacturer.

Welding and brazing procedures


Applicable codes

Welding or brazing on regulated pressure equipment in BC may require design registration and must be registered with the regulatory authority of the province or territory where the welding or brazing is to be performed, in accordance with Section 78 of the Power Engineers, Boiler, Pressure Vessel and Refrigeration Safety Regulation and CSA B51 Boiler, Pressure Vessel and Pressure Piping Code.

Welding and brazing procedures for pressure equipment made outside Canada must be registered or approved by the Authorized Inspection Agency performing the Code inspections.
