What is the term for piping that distributes fuel gas to appliances?

The term for piping that distributes fuel gas to appliances is indeed fuel gas piping. This type of piping system is specifically designed to transport gaseous fuels, such as natural gas or propane, from a central supply source to various appliances, such as furnaces, water heaters, and stoves.

Fuel gas piping is constructed to meet strict safety and building code requirements, as it must handle flammable materials under pressure while minimizing risks of leaks or combustion. The materials used for fuel gas piping often include types of steel, copper, or specific types of plastic designed for gas use, ensuring durability and safety.

Understanding the different types of piping helps in identifying their functions: water piping handles potable water, hydronic piping is used for heating systems that circulate hot water, and drainage piping is involved in the removal of waste and wastewater from buildings. Recognizing these distinctions is crucial for anyone working in commercial mechanical inspection, as it helps ensure that installations are completed correctly and safely in accordance with applicable codes.
