What are the Quality Management System requirements for a fabricator of Pressure Piping to be installed in Alberta?

October 30, 2018 By Michael Rodgers

Key Design Engineering

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

Discussion: Finite Element Analysis (FEA) in a CRN Submission

October 26, 2018 By Michael Rodgers

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

October 26, 2018 By Michael Rodgers

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?

October 26, 2018 By Michael Rodgers

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

Appendix-2 Flange Rigidity per 2008 Addenda:

October 26, 2018 By Michael Rodgers

Flange Rigidity

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.
