Valid Canadian Registration Number (CRN) Database & Directory Info

June 8, 2020/in CRN Essentials, CRN Resources /by Cameron A. Sterling

Valid Canadian Registration Number (CRN) Database and Directory Information To ensure a strong supply chain, industry often needs to locate manufacturers of CRN registered pressure equipment. Pressure piping, vessels, boilers, and thermal liquid heating systems unexempt from CRN registration need components suitable for CRN registration and, though it can be difficult to find legitimate manufacturers, […]

Is The CRN Valid and Legit?

October 31, 2019/in CRN Essentials, CRN number, CRN Resources /by Cameron A. Sterling

“It’s registered they said. Here’s the proof they said.” Really. Ok, so what can you believe? As an end user of pressure equipment (valves, flanges, fittings, instrumentation, vessels, boilers, thermal liquid heaters, etc), you are responsible for its safe operation in accordance with all applicable ASME codes, standards, and jurisdictional regulations. This means that you […]

CRNs, Maximum Allowable Working Pressure (MAWP) and Design Pressure

April 2, 2019/in Pressure Vessels /by Cameron A. Sterling

Canadian Registration Numbers (CRNs) are issued by regulators before pressure equipment is sold or used in Canada. Though there are exceptions, CRN registration is generally needed for pressure equipment that contains expansible fluids at pressures greater than 15 psig. Expansible fluids include vapors, gases, and fluids that expand to a gas or vapor when exposed to […]

Lookout For Anticipated 2019 ASME Code Changes

March 19, 2019/in CRN Essentials /by Cameron A. Sterling

As the year progresses and new codes are published, there are a few things to keep a lookout for, particularly with respect to material property requirements. Two materials are of particular interest, and are reportedly likely to change with the 2019 edition of ASME Section VIII-1. The potential ramifications of these changes on pressure equipment […]

To Design Pressure Equipment and Get a CRN; The First Step

March 6, 2019/in Pressure Vessels /by Cameron A. Sterling

We continue to rapidly explain what is needed to properly design pressure equipment (vessels, boilers, fittings, piping systems) to get CRN registration. Many designs proposed to us are deficient for the same obvious reason and consequences that stem from it. Surprisingly enough, even established and accredited pressure equipment manufacturers sometimes don’t even know the first […]
