Relief Valve Tail Pipe Design

Relief Valve Tail Pipe Design

Relief Valve Tail Pipe Design

(OP)
The main steam crossunder safety relief valves lifted at our power station, which resulted in blowing off the Turbine Building siding directly above the tail pipe discharges.  The discharge tail pipes for these relief valves exit the side of the Turbine Building on a 45 degree angle about 40 feet from the roof.  Nearby windows were also broken out (probably from the sonic shock of the discharge?).  The bank of 3 – 24”, 2 - 10” and 1 – 8” tail pipes for these safety relief valves have very little extension (less than 1 foot horizontal distance from the outside wall at the top of the 45 degree tail pipes) from the exterior wall.  I am not having any success in finding a reference for calculating the negative pressure resulting from the discharge, or a reference for the amount of extension needed for the tail pipe to ensure damage will not occur to siding/windows from the negative pressure at discharge.  Does anyone have references or other guidance for the proper design of safety relief valve tail pipes extending out of the side of a building?
