Special Concerns in PRVÆs for HP Air System.
Special Concerns in PRVÆs for HP Air System.
(OP)
We have a hp air system that charges a receiver up to 3000 psig. There are no dryers in the system, other than the accumulator acting as a moisture separator which gets drained off manually once a day. The downsteam system air will be considered as saturated.
I have to design a reducing station for compressed air that drops pressure from 3000 psig to 600 psig. This is quite a large drop to make in one step and am wondering if icing at the outlet is a concern that should be considered. And if so, what is the typical solution?
Same question applies to the safety relief valves on either side of the prv – does icing ever affect the performance or flow of a safety? And how is it to be addressed?
Is B31.1 the applicable Code for an air system or is B31.3?
Thanks
