CRN PRESSURE VESSELS
BEPeterson is a CRN pressure vessel manufacturer that designs and fabricates custom solutions for use across Canadian provinces and territories. We meet Canadian Registration Number (CRN) requirements for pressure vessels, ASME Section VIII and CSA B51. Whether you need single-province coverage or national registration for OEM distribution, our team manages the registration process on your behalf.
Technical Specifications for CRN Pressure Vessels
We build CRN pressure vessels, from small-diameter process equipment to large-scale industrial vessels, using these specifications:

| MAWP | Full vacuum up to 20,000 psi |
| Temperature | Per project requirements |
| Finishes | Primed and painted |
| Testing and NDE | Hydrostatic testing, radiographic testing (RT/x-ray), helium leak testing, impact testing, PMI, MT/PT/UT and ferrite testing |
| Post weld heat treatment (PWHT) | Per code and project requirements |
| Codes | ASME Section VIII and CSA B51 |
| Welding | ASME Section IX |
| Registration | Single-province and national CRN registration. National Board registration upon request |
| Documentation | Complete package including CRN registration records, ASME forms, material test reports (MTRs) and dimensional reports |
Projects We Have Worked On
Below are two projects that illustrate the scope of CRN work we deliver:
Jacketed Mixing Vessel for an Industrial Facility
Our client required a large-volume jacketed pressure vessel for a mixing application, with CRN certification needed for pressure vessel installation in Ontario. The specifications included:
- Dimensions: 84″ OD x 87″ T/T
- Material: 316L stainless steel
- Design pressure: 100 psi @ 275° Fahrenheit (external)
- Jacket: 1/2″ pipe jacket coil on bottom and OD
We fabricated and ASME stamped the vessel, installed the helical mixer blade prior to shipment and obtained CRN certification through the Technical Standards and Safety Authority (TSSA) for installation in Ontario.
Dust Removal Filter Vessel and Accumulator for an R&D Facility
A research and development facility in Ottawa needed two CRN-registered pressure vessels to support a dust removal system operating at high pressure and temperature. The project required two distinct vessel types with these specifications:
Filter vessel
- Dimensions: 20″ OD x 190.75″ OAL
- Material: 2205 Duplex
- Design pressure: 291 psi + FV @ 600° Fahrenheit
Accumulator
- Dimensions: 18″ OD x 40″ T/T
- Material: 304/304L SS
- Design pressure: 436 psi + FV @ 600° Fahrenheit
We fabricated both vessels to ASME Section VIII standards and coordinated CRN registration through the TSSA in Ontario. Each unit was delivered with a complete documentation package ready for installation.
The Industries We Work With
We serve different industries, including:
- Defense: We build mission-critical pressure vessels, housings and assemblies to defense program specifications, with rigorous quality controls, full material traceability and complete documentation.
- Oil and gas: Our experts build separators, accumulators and process vessels for upstream and midstream operations, rated for the pressures, temperatures and media your application demands.
- Chemical and petrochemical: We fabricate vessels in alloys that match the process media, delivering a vessel that performs as expected.
- Energy: We build process and storage vessels engineered for the thermal and pressure conditions of power generation and utilities applications.
- Industrial manufacturing: Our receivers, surge tanks and custom process vessels are engineered to plant specifications, and they integrate directly into your existing layout.
Procurement FAQs
Discover answers to common client questions:
What Is Your Production Schedule?
The production schedule depends on vessel complexity, material availability and the provincial authority’s review timeline. We discuss schedule expectations at the quoting stage and keep you updated throughout fabrication and registration.
Can You Accommodate Additional Documentation Requirements?
Yes. If your project requires documentation beyond the standard package such as third-party inspection reports, additional NDE records or end-customer-specific formats, let us know so we can build those requirements into the scope from the start.
How Do You Handle Shipping to Canada?
We coordinate shipment of completed vessels from our facility across the border into Canada. Oversized loads require permitted transportation, and we work with experienced heavy-haul carriers to plan routing and delivery.
