Natural Gas Pipeline Overpressure Protection SystemTransporting natural gas through pipeline networks requires reliable overpressure protection solutions. A series of five overpressure protection for natural gas distribution systems webcasts are now available on demand to explore the use of these solutions for safe, reliable and efficient pipeline operations. These webcasts include:

  1. Introduction to Overpressure Protection (OPP)
  2. Worker Monitor Systems
  3. Pressure Relief and Slam Shut Valves
  4. Multi-Layer Overpressure Protection
  5. Remote Monitoring and Data Collection

In the introductory webcast, Jack Gay shares the importance of deciding how many layers of OPP you need and if protection levels are properly positioned. He provides an overview of current technologies and where those technologies are used within a distribution system as well as ways to reduce complexity without sacrificing needed flexibility.

In the worker monitor systems webcast, Jack describes the advantages and disadvantages of monitor systems for overpressure protection. He explores key considerations when designing monitor systems including choosing between wide-open and working monitors, determining regulator station lockup pressure, and using self-operated or pilot operated regulators for workers and monitors. He shares effective strategies to maintain and troubleshoot monitor systems.

Jack teams with Zeeshan Saiyed to highlight pressure relief valve (PRV) selection criteria including deciding between snap action and modulating valves, self-operated vs pilot operated, and the benefits of ASME Code Stamp. They review key PRV applications, slam shut valve operation and considerations for use in natural gas systems.

In the multi-layer overpressure protection webcast, Jack describes methods and strategies to upgrade natural gas distribution systems to add a second or third layer of protection. He describes how different OPP options interact with each other as well as factors to consider when deciding which multi-layer OPP solution is right for your application.

In the final webcast in the series, Remote Monitoring and Data Collection, Robert Findley highlights why remote monitoring is critical element in an OPP solution. He shares how an effective automation strategy for monitoring and data collection allows deeper insights into OPP system performance as well as increased system safety. He describes the benefits of holistic system monitoring and control either with traditional SCADA or cloud-based SCADA systems.

Register today to view these on-demand OPP webcasts and explore the Overpressure Protection section on Emerson.com for more on the full portfolio of regulators, pressure relief valves, isolation valves and flow computers which provide the last line of defense against over pressurizing the delivery lines.
