Which material is typically used for natural gas piping?

The choice of iron pipe for natural gas piping is primarily due to its strength and durability. Iron pipes, particularly those made of steel, are capable of withstanding the pressure associated with natural gas distribution. They are resistant to physical damage, making them a suitable choice in a variety of installation conditions, including underground and above-ground applications.

Moreover, iron pipe systems are designed to be leak-resistant, which is critically important in maintaining safety in gas operations. The robust nature of iron also allows for longevity, reducing the need for frequent replacements or repairs. These attributes make iron piping a traditional and reliable option for safely transporting natural gas from supply sources to consumers.

While other materials like plastic pipe and copper tubing have their uses in specific applications, they may not offer the same level of durability, pressure tolerance, and safety as iron pipes do when it comes to transporting natural gas. CPVC, although useful for hot and cold water systems, is not suitable for natural gas transportation due to its inability to handle high pressures and its susceptibility to high temperatures.
