Let's say there is a control valve with a system upstream designed for 200 psig (i.e. the upstream relief valve set pressure). Operations plans to actually run the upstream equipment at no more than 150 psig.
There's also a a relief valve downstream of the control valve (system downstream...
I'd be curious to get some second opinions on something...
A design I'm working on currently has a steam header supplying three separate pieces of equipment (i.e. separate destinations). For each piece of equipment, there is a separate parallel connection to the header.
Which is the...
