Title: Define a natural gas system.
Course: Introduction to Energy Transmission and Distribution I (20902-36) > Section: Understanding Gas Systems

Definition should include

- components of the gas system (e.g., compressors, regulators, valves, transmission/distribution lines, heaters, pipes, gathering lines, wells, meters/metering stations, service lines, underground storage, propane air plants, liquefied natural gas [LNG], processing plants, pumping stations)
- pressure distinction
- the difference in use of steel and plastic pipelines
- the distinction between transmission class (20 percent specified minimum yield strength [SMYS]) and distribution class (<20 percent SMYS)
- pressure and volume measurements
- corrosion and its effect on buried pipelines
- the use of mercaptan.

Process/Skill Questions:

- What home appliances could use natural gas?
- Why is mercaptan added to natural gas?
- How are propane air and LNG used to supplement gas supply?
- Why is natural gas storage important, and when is it used?
- What is the difference between a leak and a rupture?
- What devices are used to internally inspect pipeline components?
