What does a gas distribution system typically consist of?

A gas distribution system is designed to safely and efficiently deliver natural gas from the source to end users, which includes residential, commercial, and industrial customers. The system comprises several key components, establishing a complete infrastructure for gas distribution.

The mains are large pipelines that transport high-pressure gas across distances to various areas. From the mains, smaller service lines branch off to connect residential and commercial buildings, delivering gas at a lower pressure suitable for use. Regulators play a crucial role in maintaining and controlling the gas pressure within the system, ensuring that gas is delivered to appliances at a safe and usable level.

Lastly, appliances, such as heaters, stoves, and water heaters, utilize the gas provided by the distribution system for various heating and cooking needs. Thus, the combination of mains, service lines, regulators, and appliances perfectly describes a comprehensive gas distribution system, highlighting its primary functions and components.
