CSA Z245.11 Fittings Meeting ASME B31.4/B31.8

CSA Z245.11 Fittings Meeting ASME B31.4/B31.8

CSA Z245.11 Fittings Meeting ASME B31.4/B31.8

(OP)
I'm new to contributing to this forum, so just want to say thanks in advance for any consideration and responses. Also thanks to everyone for past posts that I've read and learned from.

I am designing a piece of pipeline equipment and our client wants to be able to take this and use it in Canada and USA (designed to CSA Z662, ASME B31.4, and ASME B31.8). It's designed for quite high pressure and also low temp (-45C).

I've been able to source end caps per CSA Z245.11 that meet the CSA Z662 requirements. These are not dual certified, and due to the high pressures and large sizes, finding dual certified materials would be difficult and expensive. I'd like some advice on how I would ensure that this meets the ASME B31.4/B31.8 requirements please.

Per B31.8, CSA grade materials would fall under 811.1 Section b - "Items that are important from a safety standpoint, of a type for which standards or specifications are referenced in this code but specifically do not confirm to a referenced standard (eg pipe manufactured to a specification not referenced in this code)." Going to 811.2.2 a) This is a material that conforms to a written spec, but the question I have is how to validate that the CSA Z245.11 fitting meets the min requirements of this code (B31.8) with respect to quality of materials and workmanship. ASME B31.4 has similar verbage around unlisted material specs "meeting the requirements of this code".

Any advice or history on using CSA materials in ASME designs would be much appreciated. Thanks.

RE: CSA Z245.11 Fittings Meeting ASME B31.4/B31.8

you looked at the pipe design codes, now look at the specifications that you will use to purchase the components. If the specifications are equal or better than your requirements. You will use the materials down to -45C, so you must specify that the materials used be impact tested at -45C or lower. If each are certified as supplied to lower than -45C, you've proved what you need to prove. Do the same with the rest of the requirements for each component, such as maximum Carbon Equivalent, Min/Max manufacturing dimensional tolerances, etc.

Thanks for the guidance BigInch. I will look into the various requirements and compare between the codes. I guess I had been hoping that there was something I was missing allowing CSA fittings to be used per ASME codes without that level of detailed review, but judging by your answer that doesn't exist. Thanks.

There aren't any cross-over specs that I know of. You've just got to get out the magnifying glass and compare characteristics one by one.
