Large SS pipe Regulations
Large SS pipe Regulations
(OP)
Hi to everyone,
I'm working on a Stainless Steel piping specification and I have to increase the maximum diameter from 24" to 28".
The problem is that when I go the ASME B16.19, diameters 26" and 28" do not appear. I've been told there is a note that specifies that diameters that are not present in ASME B16.19 are covered by ASME B16.10 in one of those regulations. I haven't find anything about that so in my spec I will define diam 30" instead of 26" or 28".
- Are Stainless Steel 26" and 28" pipes covered by any regulation or just by "manufacturer Std"?
- What happens if you need a larger size than 30" in Stainles steel? This is the largest size defined in ASME B16.19
Many thanks,

RE: Large SS pipe Regulations
For smaller quantities, you can only buy whatever the pipe dealers have in stock. The sizes they most likely tend to have available are those "common standard" diameters and scheduled wall thicknesses that you mention. If you do not want enough pipe to warrant a special mill order with custom dimensions, stick to 24", 30" or 36". That's usually the best thing you can do on many counts. That's the reason for having common std sizes.
RE: Large SS pipe Regulations
IMO, it could be not much market application for the 26" or 28" SS pipe, so they are not listed on B36.19. But, the MFR may fabricate any size of pipes for you, i.e. 26", 28", or >30", if really want it.
