L&T High Integrity Pressure Protection Systems (HIPPS)
L&T High Integrity Pressure Protection Systems (HIPPS) Image

L&T Valves offers customised SIL-3 capable HIPPS for over-pressure protection leveraging expertise of five decades in flow-control and system integration.

High Integrity Pressure Protection System (HIPPS) is a Safety Instrumented System (SIS), which by definition, is a distinct, reliable system used to safeguard a process to prevent a catastrophic release of toxic, flammable,or explosive chemicals. The system closes the source of over-pressure within two seconds and has at least the same reliability as a safety relief valve or a flare system.

A typical HIPPS system comprises the following:

  • Pressure Sensors
  • Logic Solver
  • Final Element (Actuated Valve) which performs the emergency closure action via a Solenoid Operated Valve (SOV) to bring the process to a safe state.

Final elements (Actuated Valves) are accorded the highest priority in a HIPPS loop as studies suggest that they account for 50% of safety loop failures historically and calculations suggest that their contribution to PFD (avg) is the higher than that of sensors and logic solver. In short, performance of HIPPS is highly dependent on the integrity of the valve.

L&T Valves, with expertise in flow-control that spans five decades, is ideally equipped to design and manufacture HIPPS systems. L&T HIPPS can be offered with Trunnion-mounted Ball Valves (TMBV) or Triple-offset Butterfly Valves (TOBV) as final elements. L&T HIPPS can be supplied as a ready-to-fit skid-mounted system.

Final elements (Actuated Valves) are accorded the highest priority in a HIPPS loop as studies suggest that they account for 50% of safety loop failures historically and calculations suggest that their contribution to PFD (avg) is the higher than that of sensors and logic solver. In short, performance of HIPPS is highly dependent on the integrity of the valve. L&T Valves, with expertise in flow-control that spans five decades, is ideally equipped to design and manufacture HIPPS systems. L&T HIPPS can be offered with Trunnion-mounted Ball Valves (TMBV) or Triple-offset Butterfly Valves (TOBV) as final elements. L&T HIPPS can be supplied as a ready-to-fit skid-mounted system.

L&T Double Block & Bleed Plug Valves
L&T Valves Limited manufactures a comprehensive range of Double Block & Bleed Plug Valves in sizes up to 30” (750 mm) and in ASME classes 150 and 300. The valves are offered in combinations of size, pressure class, material, end-connection, etc to suit customer requirements. Double Block & Bleed Plug Valve provides online-verifiable high-integrity positive shut-off, and is a safe and reliable replacement for the old two-valve system. Globally, the valve has emerged as the industry standard for movement and storage of petroleum products in refineries, tank farms and terminals. L&T Double Block & Bleed Plug Valve is designed in accordance with key international standards. It also meets the requirements of major oil & gas industry standards and customer specifications. Salient features: Double Block & Bleed Valve. Mechanically-assisted sealing – Reliable bubble-tight shut-off at low and high pressures. Cavity Pressure Relief System (provided to relieve the built up cavity pressure). Non-lubricated – Sealant not required to achieve zero leakage. Unique valve operation mechanism – Segments do not rub against seats during plug rotation Cavity Relief System – Prevents body cavity pressure build-up. Pressure relieved to upstream or downstream based on customer requirement. On-line maintenance – Segments can be replaced on line. Fire-Safe Drain provided for online verification/ draining the cavity. L&T Double Block and Bleed Plug Valves (PDF)
