ASME Sect 1 Blowdown and Drain Valves
ASME Sect 1 Blowdown and Drain Valves
(OP)
I have had previous experience where different states have specific requirements for the type of vavles installed in the blowdown and drain lines of power boilers. Is there any where else in code other than Part PG that discusses specific requirements for valves placed in the blowdown and drain lines coming off of a boiler? Thanks for any input.

For boiler blowoff (periodic bottom and mud drum blowoff), many engineering companies guidelines specify Sched 160 piping due to the extreme erosive nature of the event.
I have also heard of using 2.25 Chrome moly alloy piping in this service.
