HIPPS - High Integrity Pressure Protection System

Custom-engineered safety system for isolating high-pressure sources and preventing overpressure events.

Isolates high-pressure flow at the source to reduce environmental risk and protect downstream equipment.
Achieves SIL 3 or SIL 4 integrity levels with third-party certified sensors, logic solvers, and final elements.
Customised for each site with integrated diagnostics, voting logic, and fast-acting valve assemblies.

IMI’s High Integrity Pressure Protection System (HIPPS) is a complete, SIL-certified safety solution designed to isolate high-pressure sources before they reach downstream equipment. Unlike traditional relief systems, HIPPS shuts off flow at the source, using fast-acting final elements and real-time logic. Built around sensors, logic solvers, and fail-safe valves, each system is fully tailored to your site’s pressure, response time, and safety requirements. IMI’s HIPPS combines precision engineering, third-party SIL validation, and optional diagnostics to meet or exceed IEC 61508/61511 and ANSI/ISA standards. It is ideal for applications where pressure control, safety, and system uptime are critical.
