Steel and polyethylene piping are commonly used for natural gas lines due to their durability and suitability for the transportation of gas. Steel piping is favored for its strength and resistance to damage, making it ideal for high-pressure applications and underground installations. It is capable of withstanding the forces exerted by the earth and other external conditions.

On the other hand, polyethylene piping is known for its flexibility, corrosion resistance, and lightweight properties, making it easier to install in various environments. It is particularly useful for residential and commercial applications where the gas lines may need to navigate around obstacles or be installed in less-than-ideal conditions.

Both materials meet safety standards for gas transport and are designed to prevent leaks and failures, which is why they are the preferred choices for natural gas lines. Other options, such as copper, PVC, aluminum, or wooden tubing, do not possess the same level of safety or efficacy for natural gas applications, as they may not withstand the operational pressures or could be prone to corrosion or degradation over time.
