Design pressure of PSV discharge piping - Safety

Our client is insisting that PSV discharge piping must have the same design pressure as the PSV set pressure of 1200 kPag (175 psig). Normally PSV discharge piping would have lower design pressure since it's open pipe to flare, ie pressure is limited to backpressure from hydraulic losses in the piping and flare system only.
