Con Edison Gas Operations LDP Practice Test

What are the two types of piping that Con Edison uses?

Copper and Steel Plastic and PVC Aluminum and Steel Steel and Plastic

Correct Answer:

Steel and Plastic

Explanation:

Gas piping in Con Edison’s system uses two main materials: steel and plastic. Steel provides the strength and durability needed for higher-pressure mains and rugged underground conditions, and it has a long legacy in gas distribution. Plastic piping, typically HDPE, is favored for its corrosion resistance, lighter weight, and easier installation and repair in certain parts of the network. Each material is chosen based on factors like pressure, soil conditions, and repair considerations, with joints and joining methods suited to the material—steel mainly welded or threaded connections, plastic mainly fusion or mechanical fittings. The combination of these two materials covers the common needs of the system. Other materials listed aren’t standard for Con Edison’s gas piping.
