PSV outlet piping to atmosphere design pressure? -

Hi, I believe that outlet pipe should have design pressure same as the boiler design pressure and have been defending that at my work. However, people at my work argument that since outlet pipe discharge to atmosphere, piping design pressure can be low(5K Class), since pressure over all the length of outlet will be {atmosphere + the pressure loss trough pipe}.

Boiler Feed Water System Diagram and Explanation -

In case of a feed system in an auxiliary boiler, as found on diesel propulsion ships, the drain tank or the hot well is open to the atmosphere. While in a high pressurized system, no part of the system is open to the atmosphere. A feed system, is nothing but a cyclic process that takes place between the turbine and the boiler.
