“It’s registered they said. Here’s the proof they said.”
Really. Ok, so what can you believe? Is CRN validity a thing?
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 need to ensure it is properly registered with a CRN number. You need to ensure CRN validity. CAMMAR Corp can help you do this.
“But wait a minute. Aren’t the regulators responsible for registering pressure equipment?” Nope, they aren’t. They just accept it for registration, but before the equipment is used, sold, distributed or even offered for sale, the responsibility for registering it, and ensuring that it is registered properly, rests with those who have care and control over it. Regulators don’t own it.
“Ok, but I asked the vendor if it was registered and they said it was. They even provided ‘proof’ of the registration with the CRN number. And that CRN validity is there?, so it’s registered, right?”
Uh, not necessarily.
For example, suppose your project needs some ASME B16.34 valves with a CRN number. You ask your vendor for proof of registration, and they provide you a copy of a stamped Statutory Declaration with CRN included. But what they neglect to tell you is that the acceptance letter provided by the regulator has a condition included, that goes something like this: “Only valves which comply with all aspects of ASME B16.34 in its entirety are part of this registration.”
So, what does that mean?
It means that the regulator does not always itemize which of the vendor’s valves or items meet the requirements and which do not. And with the note above, if pressure parts of any valves are made from any materials not listed in ASME B16.34 and supported by mill test reports, then those valves are not registered. There is no CRN validity for those valves. And if the flanges of those valves are improperly reamed or hollowed out, or chambered, too thin, too short, or whatever, and thereby don’t meet ASME B16.5 or B16.47 dimensions in their entirety, the valves are not registered. Etc.
So, even though there may be a CRN number, the equipment might well not be registered. And so, poof, there goes CRN validity. Despite what your vendor might tell you!
And if you were to use such excluded valves or equipment anyways, it would be like you were using unregistered equipment…! And you don’t want to go there!
