What material is preferred for gas piping?

Black steel is the preferred material for gas piping due to its strength, durability, and resistance to high pressures. This type of pipe is specifically designed to handle gas safely and is commonly used in both residential and commercial gas distribution systems. Black steel piping is less likely to corrode compared to other materials, which is particularly important in gas applications where leaks can be hazardous.

Additionally, black steel can easily be welded or threaded, allowing for versatile installation options that accommodate various building layouts. Other materials, such as brass and copper, while useful in many plumbing applications, do not possess the same level of resilience against the conditions that gas pipes typically encounter. Plastic piping is sometimes used in certain gas applications, but it must be specifically rated for such use, and its applications are limited compared to black steel. Therefore, black steel remains the go-to choice for ensuring safety and reliability in gas piping systems.
