Indeed.....I don't have a good, working knowledge of the AWWA standards, but for such a high pressure I have confidence in B31.4 for sure......maybe B31.4 with some Code relaxations where it makes sense. Probably makes sense to go that way rather than using AWWA and having to bump things up in...
Thanks for the comments. The supply is for a mine site with a significant elevation gain, which is what's driving up the pressure. The service is basically well water with an LSI ~0.5 so slightly scaling, not very corrosive. The water is for industrial use, not potable.
Hey folks, I know this topic has been brought up before in different contexts, but I have a project that is a 50 mile (80km) high pressure, fresh water pipeline that requires a minimum 600# flange rating, perhaps 900# due to transients. It's NPS30, carbon steel. We are using B31.4 as the Code of...
