High Integrity Pressure Protection Systems (HIPPS) by Pietro Fiorentini are mechanical and electrical solutions designed in order to reduce the chance that the pressure will exceed the tolerable allowable level.
These systems are used in the Oil & Gas industries to provide pressure protection of pipelines, piping, vessels and process packages against over pressure, allowing the use of lower design pressure downstream.
Compared to conventional overpressure protection design standards that are based on relief devices (relief valves and rupture disks) that discharge to atmosphere, HIPPS has the great advantage to allow lower pressure rating downstream and to avoid discharge of natural gas to atmosphere.
