What is a common material used for gas piping in home construction?

Black iron is commonly used for gas piping in home construction due to its ability to withstand the pressures associated with gas systems and its resistance to corrosion when appropriately maintained. The material has a strong structural integrity which makes it suitable for both indoor and outdoor installations. It is also compatible with the fittings and valves typically used in gas piping, ensuring a secure and leak-proof connection.

In contrast, PVC, while it has its uses in plumbing for water and drainage, is not suitable for gas piping due to its inability to withstand high pressures and temperatures associated with gas systems. Copper is often used for water supply lines but is less common for gas piping due to cost and potential for corrosion when exposed to certain gases. Stainless steel, while durable and resistant to corrosion, is less frequently utilized for residential gas lines compared to black iron, both for cost considerations and its specific applications in gas systems.
