An Introduction to Gas Distribution Systems

COURSE NO: P02-002
An Introduction to Gas Distribution Systems
Course Highlights

This online engineering PDH course provides an introduction to techniques and equipment for the design of gas distribution systems in residential, commercial and industrial settings. It covers pressure regulators, valves, meters, and other necessary appurtenances required for the distribution of fuel gas, natural and manufactured, from the point of delivery by the gas supplier to the points of connection with building piping.


Gas distribution systems consist of gas pipelines, gas reduction terminals, and gas storage facilities. Gas distribution systems are equipped with gas pressure meters, communication systems, warning systems, automatic controls, and shutoff fittings (such as shutoff valves, shutoff cocks, gate valves, and water seals) for disconnecting separate sections of the piping system or buildings during emergencies and repair work.


This 2 PDH online course is intended for mechanical and civil engineers and other design and construction professionals seeking an introduction to methods and techniques for distributing natural and manufactured gas.
