Inlet piping to PSVs
Inlet piping to PSVs
(OP)
API says that the pressure drop in the inlet piping to PSVs shall not exceed 3% of the set pressure. Common sense also gives that there should be no pockets in the inlet piping (as liquid accumulation would promote corrosion, possible water hammer effect and possible blockage if solids are present), but I cannot find any mention of in the API standards.
Does anyone know if there is a rule for that?

A pocket of liquid on the inlet or outlet side can potentially cause a lot of mechanical damage when the relief device opens.
