High Integrity Pressure Protection System
L&T Valves offers a range of customised SIL3-capable High Integrity Pressure Protection Systems (HIPPS) for over-pressure protection
In industrial plants, in case of over-pressurisation, the gases released are primarily flared. Flaring and venting of flammable gases pose health and safety hazards and constitute a significant threat to the environment.
Features
High Integrity Pressure Protection System (HIPPS) is a Safety Instrumented System (SIS), which by definition is a distinct, reliable system, used to contain catastrophic over-pressurisation and prevent the release of toxic, flammable or explosive chemicals.
HIPPS protects downstream equipment by shutting-off the source of over-pressure within seconds, and is designed to offer at least the same reliability as a safety relief valve or flare system.
