“In an emergency, the ability to rapidly shut off fluid and/or gas flow can mean the difference between a manageable situation and a potential disaster”

Operating pressure: 1040psi

Pipe Blow out , No fire.

A well designed ESD system utilized to section off the pipeline, coupled with the absence of fire, made this one a non event!

ESD control solutionsESD control solutionsESD control solutionsESD control solutions 20 years ago, a liquid spill or gas

released was not a major event.– Historically, sectioning valves on tank

farms, liquids lines , aggressive pressurized gases etc.. have been electrically actuated due to their remote location.

– With today's environmental standards and required practices, the need to have ESD capabilities becomes prevalent and changes the operational function of sectioning valves.

– The lack of spring return capabilities from the different electric actuators designs on the market and its dependence on the supply source to operate and react to any given situation know makes the users vulnerable to dangerous situations and potential environmental catastrophes.

How can we define an ESD valve/damper system?– A packaged solution or sets of controls configured to

make a rotary or linear actuator go to a desired position upon detection of a set or sets of event(s), autonomously or by dedicated signal.

– Emergency Shutdown (ESD) Valves and other fail-safe valves and dampers assemblies, typically incorporate a spring-to-fail actuator to stroke the valve or damper in the event of an upset process condition.

configured to answer to the designation of Emergency Shut Down (ESD) valve will provide protection on;

– Pipelines

– Storage facilities in refineries

– LPG

– Chemical

– Tank farm

– Loading and unloading facilities

– Process

– Wellheads

– Liquids lines

– Liquefied gases

ESD systemsESD systemsESD systemsESD systems Typically used on on/off isolation or sectioning

valves, controls can be devised to incorporate ESD logic into control valves packages.

Most often installed on ball, plug, butterfly, gate and globe valves, solutions can be self contained or integrated into a ESD system.

From local to remote triggering, we must first determined the parameter and means by which we will “trip” the actuator to fail close or open on each applications.

In anticipation of customer requirements to provide a system that will not only provide linebreak protection but also monitoring and analyses of pressure characteristics, Bettis has designed our next generation electronic linebreak system. The LineGuard system incorporates everything Bettis has learned about pipeline protection which is…well, a lot. Again, Bettis leads the World in valve actuation systems.

• Initiates valve shutdown on set high and low pipeline pressures. Initiates valve shutdown on a set rate of pipeline pressure fall.

• Monitors (every 5 seconds) and records pipeline pressure to provide a detailed insight into the pipelines operating characteristics prior and post to valve shutdown.

• Allows optimizing of setpoints for effective linebreak control.

• Remote communication and control using industry standard MODBUS protocol.

ESD Self contained solutionESD Self contained solutionESD Self contained solutionESD Self contained solutionThe standard SCH control system always requires at least one additional control component to initiate valve shutdown. This type of component is used to initiate the depressurization of the system allowing the actuator’s spring to move the mainline valve to its failed position. Most common of these shutdown devices are pressure pilot valves, solenoid valves and manual ball valves.

The picture shows a Pressurematic Pilot fitted with a manual reset valve (P-MR type) being used as the shutdown device.
