Pump Station Pressure Relief System

In all of the pump stations, piping pressure relief systems have been designed to keep existing and surge pressures from exceeding 110% of the pipe’s internal design pressure. Pressure relief for each pump station is provided by connecting the suction and discharge relief valve piping manifolds to the crude tanks. Connection to the tanks varies for each pump station. Each station has either two or three hydraulically operated pressure relief valves on both the suction and discharge side of the station, except Pump Station 4, which has only suction relief valves.
