Is black pipe OK for natural gas?

Answered by Ricardo McCardle

Black pipe is not suitable for carrying natural gas. It is made of steel, which makes it strong and durable. However, it does not have a protective coating like galvanized pipe does. This lack of coating makes it susceptible to corrosion, which can lead to leaks in the pipe. When it comes to natural gas, leaks are a serious concern as they can be highly flammable and pose a safety risk.

Natural gas is typically delivered to homes and businesses through pipes made of steel or polyethylene. Steel pipes are commonly used for larger applications, such as main gas lines, while polyethylene pipes are often used for smaller residential connections. In either case, it is important to use the appropriate type of pipe for carrying natural gas.

Galvanized pipe, on the other hand, is coated with a layer of zinc. This coating helps to protect the pipe from corrosion, making it a suitable choice for carrying water. However, it is not recommended for carrying gas, as the zinc coating can react with the natural gas and cause blockages or clogs in the pipe.

In my personal experience, I have seen instances where black pipe was mistakenly used for natural gas lines. This resulted in leaks and potential safety hazards. It is crucial to use the correct type of pipe for each specific application to ensure the safety and efficiency of the gas system.

To summarize, black pipe is not suitable for carrying natural gas due to its lack of protective coating. Galvanized pipe, while suitable for carrying water, should not be used for gas lines as the zinc coating can react with the gas. It is important to use the appropriate type of pipe for each specific application to ensure safety and reliability.
