Piping engineering is a critical discipline in mechanical and process industries, responsible for the design, layout, and integrity of piping systems that transport fluids, gases, and slurries. These systems serve as the arteries of power plants, oil & gas refineries, chemical facilities, and water treatment plants. A piping engineer ensures that these networks are not only functional but also safe, cost-effective, and compliant with industry codes like ASME, ANSI, and API.
