Each province or territory in Canada issues the Canadian Registration Number (CRN) by an authorized safety authority for pressure vessels and fittings that operate at a pressure rating greater than 15 psig. The CRN identifies that the design has been accepted and is registered for use in that province or territory.
1. The first step is to determine what province or provinces the equipment will be operating in. It is important to note that each province or territory has unique application criteria for CRN. If the equipment will be used in more than one province or territory, a separate CRN application is required.
Timing is also discussed early in the project, so customers understand what is involved in the CRN application process. Upon determining the design and shipping requirements, it may take several weeks for the CRN number to be granted depending on the project’s complexity.
2. Next, approval drawings are developed for specific CRN parameters. Fittings, piping, and components need to be verified through detailed calculations or testing. Further, some provinces and territories require a PE (Professional Engineer) stamp. Documentation for drawings and materials is prepared per the requirements for the specific provincial CRN application.
3. Depending on the complexity of the vessel, the design verification may require changes and modifications. This involves back-and-forth consultation with both the customer and the reviewer of the registration.
4. If required, our Quality Assurance team schedules and performs tests to comply with the vessel’s certifications and prepares the testing and certification documents.
5. Finally, the CRN number is issued, and equipment only then can be shipped and placed in service.
Custom vessel manufacturing for industries and pressure vessel factions requiring compliance is what we do. There is a process for customer service and project engineering that we follow to get the correct solution with the defined compliance. Apache sales techs and engineers work with customers to explain this process and provide options when necessary to manage your custom vessel project.
Experience and reputation are significant when developing relationships with inspectors, agencies, and governing officials to keep the CRN registration process moving forward. Having exported to Canada for over 40 years, Apache’s small vessel and large tank team have extensive experience with Canadian regulatory requirements and documentation.
