2" SCH 80 Minimum for B31.8 BW Piping
2" SCH 80 Minimum for B31.8 BW Piping
(OP)
Hi,
I have noticed that a number of companies will utilize SCH 80 minimum wall thickness for 2" piping regardless of what the minimum wall thickness indicates per the calculations, even for 150# or 300# systems.
I understand that threaded piping would potentially require SCH 80, but this is being done for butt weld piping too.
Anyone have thoughts on this practice? Is it somehow related to CFR 192 code?
Thanks

Savings of metal are low and you don't have to worry about having the wrong size.
2" pipe is often stupid on or used as handholds so sch 80 is a good idea
No code issue AFAIK
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
