Gas piping systems are designed to safely transport gas, and this requires adherence to specific materials and construction practices. The characteristic that states gas piping can be made of any material is incorrect because there are stringent regulations regarding the types of materials that can be used for gas piping. Typically, materials like black iron, steel, and certain types of plastic are approved for gas piping, while others, such as certain metals and materials not designed to handle the pressures and properties of gas, are prohibited to prevent leaks and potential hazards.

Recognition of the importance of using appropriate materials ensures not only safety but also compliance with industry standards and regulations, which establish guidelines for the construction and operation of gas systems. Other characteristics mentioned, such as using color-coded systems for safety, regular inspections, and adherence to codes and standards, are integral for promoting safety and reliability in gas piping installations.
