There have been "black iron" pipes (actually steel pipes with the black oxide from the mill) in service underground for close to 100 years with little or no failure.

In many areas of the country, black pipe is required for natural gas lines because of the way it is made. This kind of pipe is created as a long, continuous tube. JM Eagle indicates that this kind of pipe is also preferred because it is "lightweight, non-corrosive, available in coil lengths, and easy to install by heat fusion or mechanical fittings."

The short answer: Yes, all metals can corrode. If nothing ever touched the pipes, the cast iron could last for 75 or more years. But think about your sewer pipes. They are most likely being used every single day.

Estimated life span – 75 to 100 years Correctly installed reinforced concrete pipes can last for a lifetime. These pipes are manufactured using concrete made from cement, fly ash, aggregates, and water. (Read also: Why Reinforced Concrete Pipe is Ideal for Pipejacking.)

Re: Natural Gas Black Pipe Life Expectancy; Author: rsk (NJ) Thanks for your input packy. The meter is close to the house and then pipe runs through the garage to the utility closet.
