Is CRN# Required to be included on U1 form for Mass Produced Vessels

[LRMECH]

Hello All,

I have ran into an issue with one of our Canadian customers. They are telling us the it is a requirement for the CRN# to be inclded on the U1 form for massed produced U-stamped accumulators per ABSA.

Our accumulator vendor is saying this is not a requirement.

Our company has sent hundreds of these accumulators to Canada without the CRN# on the Ul form and this has never been an issue....until now.

Here is a little back story that may help:
The accumulator vendor buys shells and places them in stock. When an order is received for a CRN accumulator, they take a stock shell and stamp the CRN# on the shell. However, the shell manufacture does not know the end destination for the accumulator, so they have no way of knowing if the shell needs a CRN#.

Thank you for any help with matter!

LRMECH, this is coming only from your customer, right? So, first, confirm with ABSA that CRN on the U-1 is not required under these circumstances. Second, explain to the customer that it is not possible to have the CRN on the U-1, offer that it be placed on another document where it is feasible to do so.

Also, unfortunatley, "Alberta" is not necessarily "Canada". It's like a whole 'nother juridsiction

Regards,

If the vessels are intended to be shipped to any prov. In Canada needs to be proper crn certified with its corn numbers or numbers... Forget the customer, if you get caught you w,o' proper docs and crns. You will suffer the consequences. Because the vessel
Las have to be reg. W. The n.b. if you do not add the corn on the data s. Then its not properly registered.

LRMECH,

Are the CRN's already provided for the accumulators prior to completion of fabrication, or are they completely fabricated without an applicable design being registered in Canada? I mean, is the design only submitted for registration in whatever Canadian province the product is being shipped to, after the accumulator is in stock?

If the manufacturer is mass producing accumulators to the same design and they are being shipped to various provinces in Canada, then why not get the design approved in all provinces? Then any time they construct an accumulator to that registered design, the same CRN can be applied to every new accumulator U-1 form that's built to that design.

Typically, a CRN consists of one main number, followed by a decimal, and then a digit to show what province the design was first registered in. Each province has a different digit. If the design is registered in more than one province, the CRN number stays the same, except another digit is added onto the end to show the number is registered in another province. I.E. CRN A1111.2 is registered in Alberta. If the design is subsequently sent to Saskatchewan for registration, the new number would be A1111.23. If the design is registered in every province and territory in Canada, the CRN would be A1111.C.
All accumulator's built to the approved design, whether they get installed in Canada or not, could be stamped with the applicable CRN, which would take care of the issue you're facing.
One related issue I've seen on numerous occasions is with the drawing number shown on the front of the U-1 form. The drawing number shown there should be the approved CRN drawing number and revision. If items are constructed to the same design, but to a different drawing number, the different drawing number should be noted in the remarks area of the U-1. I've often seen the mistake made of putting the different "constructed to" drawing number put on the front of the U-1, which happened to be a completely different number than the CRN drawing number.
Often, if the drawing number shown on the front of the U-1 form matches the CRN drawing number, but the CRN area is just left blank on the U-1 form, the CRN number can be handwritten in there and initialed by the NB inspector, but that's up to the discretion of the pressure equipment authority of the province.

Sorry for the long-winded response, but I hope it helps somewhat.
