What material is commonly used for gas piping in residential applications?

Copper
PVC
Steel
Rubber

The correct answer is: Steel

Steel is commonly used for gas piping in residential applications because it provides a durable and strong solution that can withstand high pressure and the corrosive nature of some gases. Its ability to handle elevated temperatures and pressures makes it a reliable choice for transporting natural gas and propane. Additionally, steel can be welded or threaded to create robust and leak-proof connections, which is essential for safety in gas installations. While copper is occasionally used in some installations for natural gas, it is not as prevalent as steel because it can corrode more easily, especially in the presence of contaminants. PVC is not suitable for gas applications due to its inability to hold up under pressure and temperature fluctuations, making it unsafe for transporting flammable gases. Rubber is not typically used for gas piping as it can deteriorate over time when exposed to gas, leading to potential leaks and safety hazards. Thus, steel stands out as the preferred material for gas piping in residential settings.
