Minimum Wall thickness for open drain lines
Minimum Wall thickness for open drain lines
(OP)
Hi Guys,
I'm supposed to do wall thickness calculation for open drain lines while design pressures are "0". I couldn't find any criteria in ASME B31.3. Do you know how can I get it done?

RE: Minimum Wall thickness for open drain lines
Look to see that the pipe's diameter to wall thickness (D/wt) ratios in your code are satisfied. The maximums are often near a value of 100 or so.

Yes, a 12 foot drain line could be purchased separately, stocked separately, stored separately, and installed separately and NDE'd separately from the rest of the 1200 foot pipes needed for a project .... but at what extra real-world cost?

I think I had to explain it more. this is a maintenance job so I hd to calculate the minimum require thickness with the available corroded thickness. reverse!

Thnks for your very practical guideline
