The ASME VIII-1 code’s general approach to bolting is stated succinctly in ASME VIII-1, Appendix S-1:
When do Flanges need to be Registered?
When the flanges are to be used on a piping system, then they must carry their own Canadian Registration Number (CRN).
What are the Quality Management System requirements for a fabricator of Pressure Piping to be installed in Alberta?
1. Canadian Fabricator in Alberta Must have an Alberta Certificate of Authorization that covers the required Code of Construction, such as B31.1 an ABSA A1 does not need to inspect the piping system, since the manufacturers are qualified to perform the inspections. 2. Canadian Fabricator not in Alberta Either: A) Must hold a Certificate of Authorization from the local jurisdiction, that permits construction of pressure piping and doesn’t require inspection
How can a CRN be obtained for Sanitary Tri-Clamp?
What Code calculations can be done to validate a Trip-Clamp sanitary fitting for CRN registration in Canada?
Registering Flanges Conforming to SAE J518 Standard
SAE J518 covers the specification of four-bolt split flanges that attach tubes, pipes, and hoses to applicable ends. These flanges are intended for use in hydraulic applications.
Discussion: Finite Element Analysis (FEA) in a CRN Submission
The jurisdictions’ stated purpose is to ensure the safety of the design. In practical terms, this means code compliance. Traditionally, some of the driving motivations for FEA could be: reducing prototyping costs, shortening the time-to production, and ultimately resolving complex design challenges. However, in the present case, the focus is product safety by ensuring code compliance and it can be quite baffling for experienced finite element analysts to have their
TSSA: Code Adoption
CSA B51: In Ontario, TSSA does not automatically accept all of CSA B51’s definitions and positions for boilers and pressure vessels. The jurisdiction has the final authority, and can choose to accept or deny any code, or portion of code, as they deem fit. Furthermore, TSSA can also apply their own interpretation to the codes that they allow. TSSA’s Code Adoption Document (BPV-08-01), published May 1, 2008, lists what sections
Is a CRN Required for Hose at ABSA?
As noted in ABSA Information Bulletin, IB10-004, which references CSA B51-09 Clause 8.2, flexible hose assemblies don’t need to be CRN registered in Alberta if they are manufactured to RMA IP-2, which is the Rubber Manufacturers Association (RMA) Hose Handbook

General Requirements: When does a Piping system require CRN registration in Alberta?
Appendix-2 Flange Rigidity per 2008 Addenda:
Have the flange rigidity requirements been annulled? No, but the 2008 Addenda to the ASME VIII-1 Boiler and Pressure Vessel Code does have an interesting revision to Appendix-2, governing custom-designed flanges.
