Pipe schedule for H.P. Liquid NH3
Pipe schedule for H.P. Liquid NH3
(OP)
What schedule wall thickness is required for 2 inch H.P. NH3 piping. Also, what methods of hanging or attatching large dia. pipe to the building structure are considered safe or are industry standard for an area that does experience some moderate seismic activity?

Do you have a specific design pressure for the ammonia? Seismic zone or at least location? All of that might help you get a reply you can use.

I briefly worked on a facility that fell under these regulations as they were using ammonia to control NOx emissions, there were some very specific design issues that were specified (down to the range of pressure gauges) and I believe 2" pipe had a minimum schedule specification.
