Selected Cases

              CRN Application Design Calculation:

This project is to design an new flange fitting used in refinary. PetroPi provide code calculation and FEA analysis  to assure the compliance with the requirements of the ASME Boiler & Pressure Vessel Code, Setion VIII, Divsiopn 1 per ABSA (Alberta Boilers Safety Association) requirement. 

ABSA (Alberta Boilers Safety Association) is the pressure equipment safety authority for Alberta. ABSA administers Alberta’s pressure equipment safety programs under the Safety Codes Act, and has the authority to enforce pressure equipment safety as set out in the legislation.

Designs & Engineering Services

CSA B51, the Canadian “Boiler, Pressure Vessel, and Pressure Piping Code”, describes the use of CRNs in detail. Part 1, Clause 4 specifies that pressure fittings, pressure vessels, and boilers are assigned CRNs with the acceptance of regulatory authorities in provinces where the equipment is to be used.

Fitting for use in Canada in connection with any boiler, pressure vessel or pressure piping system shall apply for registration of the fitting.

PetroPi can provide engineering designs, registration of designs, and obtaining the Canadian Registration numbers (CRN) for pressure fitting used in Alberta Canada.

CRN Registration for Pressure Fitting

Canadian Registration Numbers (CRNs) identify unique pressure equipment designs for use in Canada. Each design concept has a unique number. One Canadian Registration Number can represent millions of individual items, each with a different serial number, that all conform to the CRN design.

Canadian provincial regulatory authorities have cooperated to help ensure CRNs are tracked nationwide and identifiable across provincial boundaries. CRNs are stamped on equipment or, in the case of very small fittings, trackable with other identification markings.

    CRN Application Design Review and Approval:

This project is reviewing the existing drawings for the purpose of application of CRN number. Petropi reviewed the drawings per ASME VII Div 1. Veriftie that the welding, wall thickness, materials are meet the code requirement.
