What is the rule of thumb for CRN number registration?

What is the rule of thumb for CRN number registration?

What is the rule of thumb for CRN number registration?

(OP)
Who knows the rule of thumb for CRN number registration? What kinds of vessel doesn't need to be registered? Size? Pressure?

Thanks.

RE: What is the rule of thumb for CRN number registration?

For the Alberta specific requirements you can go to www.absa.ca and they have a link to Design Registration.

It will require a CRN in Alberta if it is to contain expansible fluid in excess of 15 PSI.  The pressure diameter combination will simply determine whether it is a fitting or a vessel CRN.  In the case of a fitting it would not require 3rd party inspection involvement.  This would be similar to a UM vessel.

It should also be noted that a vessel to come to Alberta (where I am located) from outside of Canada MUST have an ASME code stamp and be registered with the National Board along with bearing a CRN.

Larry,

In Alberta, Figure 1(b) in CSA B51 is used as a guide to determine if a small pressure vessel can be treated as a category H fitting. However, the Administrator has final say over whether an item may be registered as a fitting or must be registered as a pressure vessel.
See: Figure 1(b) in CSA B51

You can find more info here.

Thanks for all of you. After I get the more specific info for the pressure and size, I may talk to ABSA to make sure it is a vessel or fitting registration.

I am also curious about fitting registration. I think the fittings from vendor have been registered. But I knew some times say 10" equal tee c/w 10"x8" reducer also need to be registered after welding, are there any rules of thumb?

Probably the best I have seen. If you job this out to a French speaking Canadian PE that helps as well.

RE: What is the rule of thumb for CRN number registration?

You don't actually say what province you're needing this for. ABSA is for Alberta only. Each province has it's own boiler/pressure vessels/pressure piping organization.

If it's for a province other than Quebec or possibly New Brunswick, I can't imagine having a French speaking or bilingual engineer would help very much.

Just relating past years and "best practice" no offense intended. Most manufactuers in the US submit to Quebec first, and if that goes well the rest will follow.

RE: What is the rule of thumb for CRN number registration?

You may want to consider submitting to Alberta first.  They recieve around 10000 design submissions per year.  They are the toughest and most other provinces will accept their registration without many questions.  They have a design review team of 10 very capable individuals and know the codes well enough to recite them in their sleep.

I even know of a case where an Australian company called ABSA for guidance on ASME code impact testing when the vessel wasn't going to Alberta.  A couple of oil companies have an internal requirement that equipment must have and Alberta CRN regardless of the location of construction or location of installation.

Yes, I agree they are tops. Have great respect for Dr.Lau.

If you do tubesheets...UHX. If you use UW-16 make sure you review the new Code edition.

It is also best if there are no "gray areas".

RE: What is the rule of thumb for CRN number registration?

eliebl,
Are you as salesman for ABSA? Just kidding.  I agree, the Survellence Engineers in ABSA are a really fine bunch of guys and very knowledable.  I really like dealing with them.  The people in TSSA is also excellent.

deanc,
That is a really good FAQ page. Thank for the link.  

RE: What is the rule of thumb for CRN number registration?

I used to work there.  I had a lot of respect before I was employed there.  I have more respect for the job they do now that I have worked there.

Always helpful.  Some (maybe many) see them as an impediment but I regularly recieved comments that manufacturer's felt the input from ABSA on their designs made them better.

RE: What is the rule of thumb for CRN number registration?

(OP)
It is in Alberta.

RE: What is the rule of thumb for CRN number registration?

You also need to determine if the equipment is for a pressure vessel or piping application.  ABSA's mandate only covers pressure vessel applications and do not consider piping.  I fact, I do not think they even have a copy of CSA Z662.  I could be wrong on this, but Design Survey isn't really up on piping codes (great on BPVC though).

RE: What is the rule of thumb for CRN number registration?

ABSA is responsible for piping if it is within the plant boundaries but when it is outside the plant and Z662 (other than clause 14 steam piping) it is outside of their jurisdiction.  If you go the the Alberta Energy and Utilities Board website there is a document somewhere (it's tough to find) which has pictures of where the jurisdictional limits fall.

RE: What is the rule of thumb for CRN number registration?

Actually ABSA DOES do PIPING just not PIPELINES. smile

-SLH

AEUB has a document for determining jurisdiction. I've never looked at it because I've never needed it, but it should be here:

(if that doesn't work ABSA has a link on their webpage)

RE: What is the rule of thumb for CRN number registration?

We were just told that we did not need to be registered in Quebec because we did not meet the 2.8 sq. meter 'wetted surface area' requirement.
