Asme section viii boilers and pressure vessels ug 135 d-1
(OP)
My understanding of ug 125 to 137 is that every PV needs a relief with no block devices between it and the pv except in 135 d-1. I don't completely understand this clause.
Can someone provide an example where block devices can be installed. Not counting appendix m

Second question:
Can you have a isolation valve between the relief and supply of the vessel since it isolates the exchanger thus not affecting the relieving capacity.

My understanding is that if the exchanger is isolated from the the PRV and energy source, there still could be a fire, unexplained source of heat that could cause the exchanger to explode.
