Canadian Registration Numbers (CRN)

Canadian regulations require a valid Canadian Registration Number (CRN number) for most pressure equipment, fittings, piping systems, pressure vessels & boilers operating over 15 psi (1 bar).

For over a decade Titan Research Group has helped leading global engineering & manufacturing companies with CRN applications.

We provide:

  • ASME Code Calculation (ASME, API)
  • Witnessed proof testing
  • CRN project management
  • Code training and knowledge transfer
  • CRN Application documentation completion

Trusted by industry:

We tackle all CRN number projects

The Canadian Registration Number application & renewal process can be complex, and depending upon the type of pressure equipment, whether for fitting registration, Pressure vessel (pv engineering), piping systems etc. registration requires comprehensive ASME code calculations (American Society of Mechanical Engineers). Where witnessed proof testing is required, we can provide the facilities and witness to qualify the most difficult pressure boundaries at very high pressures and even temperatures. A well informed & strategically planned application for your pressure equipment design can lead to rapid approval from TSSA, ABSA, ACI central, BC Safety Authority, Manitoba, RBQ, and Saskatchewan or any of the 13 provinces or territories individually. We ensure a strategy that permits you to make trouble free renewal down the road.


We are CRN code Gurus

Titan Research Group staff attend ASME code and standard committee meetings regularly & stay abreast of the latest pressure laws, regulation updates, director’s orders, minister’s orders, safety authority news, and code adoption documents. Titan Research Group also acts as a Canadian delegate for the ASME Bioprocessing Equipment Standard committee, with bioprocessing projects and contacts across North America.

We make the CRN number process look easy

In addition to engineering tests and calculations, applicants for Canadian registration number need to submit province & territory specific documentation when applying. Titan Research Group will help you prepare all the necessary application paper work for ABSA, TSSA and the rest and provide specific instructions. We will track your project and support it to its completion.
