Equivalent Standards

Equivalent Standards

Equivalent Standards

(OP)
I'm working on a recurring class and in the first go round I got asked "what is the Canadian equivalent of ASME B31.8?".  After a few seconds of brain-racking I had to admit I didn't have a clue.  I've been looking for the last hour or so and think I've found that the Canadian and ISO closest approach to ASME B31.8 is:

-  CSA Z6662-07
-  ISO 13626:2009

Is that right or has my Internet search skills let me down once again.

David

RE: Equivalent Standards

Z662-2007 is the B31.8 counterpart.

The ISO standard ISO 13626:2009 may have some relevance and overlap into B31.8, but to my knowledge it has more to do with drilling and production facilities, not principally pipelines.

Regards,

SNORGY.

Thanks, the write up in Tech Street was very similar to a combined B31.8 and B31.4.  Maybe someone else has some clarification.

David

RE: Equivalent Standards

In Canada we used to have two separate documents CSA Z183 and Z194 for gas and oil pipelines (similar to B31.4 and B31.8). However, many years ago it was decided that there was a lot of overlap between the documents so they were consolidated into a single document Z662 which covers "Oil and Gas Pipelines".

With regards to the actual requirements, I think there are some differences in approach between Z662 and B31.4/B31.8. It's not based on the ASME documents.

I'm really not very familiar with European ISO standards but I think the nearest ISO equivalent may be ISO 13623 "Petroleum and Natural Gas Industries - Pipeline Transportation Systems".

 

RE: Equivalent Standards

ISO 13623 is also known as EN 14161:2003
It does not cover onshore gas supply, nor oxygen systems.

Quote:

This (EN 14161:2003) European Standard specifies requirements and gives recommendations for the design, materials, construction, testing, operation, maintenance and abandonment of pipeline systems used for transportation in the petroleum and natural gas industries.
It applies to pipeline systems on land and offshore, connecting wells, production plants, process plants, refineries and storage facilities,

EN 1594:2000
Gas supply systems - Pipelines for maximum operating pressure over 16 bar - Functional requirements.

Quote:

This (EN 1594)European Standard is applicable to pipelines with a maximum operating pressure (MOP) over 16 bar for the carriage of processed, non-toxic and non-corrosive natural gas according to ISO 13686 in onland gas supply systems, where: - the pipeline elements are made of unalloyed or low-alloyed carbon steel; - the pipeline elements are joined by welds, flanges or mechanical couplings; - the pipeline is not located within commercial or industrial premises as an integral part of the industrial process on these premises except for any pipelines and facilities supplying such premises; - the design temperature of the system is between -40°C and 120°C inclusive.
...
Gas supply systems covered by this standard begin after the gas producer's metering station. The functional demarcation of the pipeline system within a plant area will be determined from case to case. Generally speaking, this will be directly after the first isolating valve of the installation.

Others also apply, and local country regulations may be more stringen too.

Welding requirements are described in a special application standard on welding for gas supply systems EN 12732.  Functional requirements for stations are given in: EN 1776, EN 1918-5, EN 12186, EN 12583, ISO 14313 Valves, ISO 21809 Coatings, ISO 3183 Pipe.

RE: Equivalent Standards

BigInch,
Thanks for that.  In my talk I list them as "Complementary Standards", not "Equivalent Standards".  Basically I'm trying to tell folks that there are standards of construction and to point towards them.  It is upstream gas gathering, so not covering oxygen or distrubition piping is fine.

David

RE: Equivalent Standards

I was going to make a note that they are really not equivalent at all, but I was sure that's what you ment.

If you get an offshore question, DNVs are popular
DNV-OS-F101
DNV-RP-F101

If I get an offshore question, I have my blank stare down pat.  No Habla offshore construction.  The only "offshore" I ever did was 1/2 million miles in an enginroom on a Navy ship.

David

RE: Equivalent Standards

That qualifies you for project manager.

RE: Equivalent Standards

David-

Make that "No hablo offshore construction."

Since we're nitpicky engineery types... Though this really belongs in one of the "soft" fora...

jt

RE: Equivalent Standards

(OP)
I know even less about languages than I do about offshore.

I put it here because we discuss codes here all the time.  It was either here or in the Codes & Standards forums and those guys can get a touch pedantic.  I never considered the soft forums and I don't think that that would have been an appropriate place for this question.

David

RE: Equivalent Standards

That's 1/2 the reason why I made him project manager.  smile

Guess I should've put that one in my first post...

You mean you aren't a "soft forum" kind of guy?  I never would have guessed...

Nothing wrong with being a hard-core engineer.  Beats the heck out of being an MBA.

RE: Equivalent Standards



Perhaps some of the CSA differences might be related to low temperatures, potential beaver bites, moose tramplings or polar bear attacks.

David: a half a million miles of piping on a navy ship must have represented REALLY small, VERY high pressure tubing. Was that thing some kind of military super-secret, floating research project?

I know, I know...if you tell me you'd have to kill me, etc.

 

RE: Equivalent Standards

(OP)
Not "half million miles of piping", I was on a ship that never saw port and always went fast.
