NSF-61 certified expansion joint or hose for tank nozzle
NSF-61 certified expansion joint or hose for tank nozzle
(OP)
Hello folks.
I have an AWWA potable water tank on a gravel pad. Design consolidated settlement is in excess of 1.5 inches. The piping is not particularly flexible, so I need an expansion joint between the tank and the closest pipe support. Can anyone suggest suppliers from whom I might source NSF-61 certified hose / joint for potable water (drinking water) service?

What a bonehead move on my part for not mentioning that. I am sorry for that, because that is at the centre of my problem.
Sizes involved are 2" NPS, 3" NPS, 4" NPS, 6" NPS, 8" NPS and 10" NPS, all flanged 150# RF x 150# RF, proposed 304L SS.
The real issue is the combination of poor foundation design and even worse piping design, exacerbated by the fact that it is a glass-fused-to-steel tank with allowable nozzle loads of zero.

but they may have testing on the standard product line as well

Installing the piping in this manner is probably a better solution than an expansion joint on a straight out piping arrangement.
