    HIPPS - high integrity pressure protection system

    What is a HIPPS?

    HIPPS (High Integrity Pressure Protection System) are system-critical systems with valves designed to protect downstream systems from over-pressure events. They are specifically designed to react quickly in closing a pipeline or flow line. HIPPS function autonomously, operating independently of process shutdown, emergency shutdown or control systems.

    How does a HIPPS? work?

    A HIPPS is a system that closes the source of over-pressure within a specified time with at least the same reliability as a safety relief valve. HIPPS is a functional loop consisting of:

    • Sensors/Initiators that detect the high pressure (usually 3)
    • A logic solver control system, which processes the input from the sensors to quick-closings hut off valves to shut the source of over-pressure
    • A valve, actuator and solenoids

    What applications require HIPPS?

    HIPPS prevent over-pressurisation between high-pressure and lower-pressure systems in gas, chemical and oil refinery plants and subsea applications.

    To have plant operation stopped due to a single point of failure is totally unacceptable. HIPPS ensures the protection of downstream equipment against overpressure and allows the continued use of lower-pressure piping and equipment downstream.

    At Winnellie Valve and Process we have the capability to design and fabricate complete HIPPS systems for either surface or subsea applications to meet your requirements. We tailor your HIPPS system by selecting the appropriate valves, actuators and controls, all certified to SIL 3 reliability and the latest international standards.

    To procure the correct, tailor-made HIPPS for your application contact one of our valve experts today.

    How do you install a HIPPS?

    It’s always best to have a qualified technician install your valves for industrial applications. However if you want to be able to install a HIPPS yourself, contact a valve expert to guide you through the process. Winnellie Valves and Process also provide valve training courses for all types of valves and process equipment.
