Question about Natural Gas lines
Im in the utility industry, specifically Electrical distribution/transmission. Lots of protective devices and what not.
Just starting wondering, what type of protection devices exist in natural gas lines running through a community?
Say for example a pipe were to be damaged and opened to the atmosphere, or worse, some kind of ignition. Would pressure sensors detect a pressure change and activate some kind of remote isolation or shutoff to prevent a chain reaction back upstream to the source?
Just curious how these systems are protected during emergency scenarios. Similar to electrical faults and such.
