Plant Engineering | Five common steam line sizing errors

May 01, 2005 · Undersized piping downstream of pressure reducing valves. Assume the boiler is set at 200 psig, 2-inch steam lines are used, and a 2-inch pressure-reducing valve (PRV) is specified to provide the 50-psig steam required by the process. However, the same 2-inch piping for the PRV inlet is used for the outlet. This is the third common problem

Set-up and design for a steam-pressure-reducing valve station

What is Steam Pressure Reduction? Steam pressure reduction is the lowering of the steam pressure at the boiler plant by means of the pressure . setting on the boiler plant master control. Steam pressure reduction affects mainly the high pressure part of the steam system. Within practical limits, pressure-reducing valves (PRVs) will adjust the pressure at lower levels to the previous set points. This
