What does a natural gas regulator do?

 In Natural Gas

What does a natural gas regulator do? Throughout the gas delivery system, from the well to the stove burner, regulators are used to adjusting the pressure to ensure safety. In this back to basics entry, I discuss why natural gas pressure regulators are used in a delivery system.

Natural Gas Regulators

After natural gas makes its way out of the well, into gathering and transmission systems, and gate stations, it ultimately enters distribution lines (or “mains”).

While gas is in the distribution system, regulators control the flow from higher pressure to lower pressure. Regulators sense if the pressure in a line drops below a specified set point and opens, allowing more gas to flow. On the other hand, if demand rises above a set point, the regulator will close so that the downstream pressure adjusts.

When natural gas leaves the main, it travels through a “service line” to reach homes or businesses. This service line is likely to be polyethylene, perhaps an inch or less in diameter and ranges from about 60 PSI to ¼ PSI. Once the gas reaches the home or business meter, it passes through another regulator to reduced the pressure under ¼ PSI and is measured in a water column.

Throughout the gas delivery system, from the well to the stove burner, regulators are used to adjusting the pressure to ensure safety.

    What happens if high pressure regulator is used on low pressure setting

    Russell,
    As long as the inlet pressure is higher than the outlet pressure the regulator will function, but the amount of natural gas that will flow through it will be greatly reduced and the outlet pressure will tend to drop off sooner.
