Piping systems in a chemical plant (refineries, petrochemical plant, fertilizer plant etc.) are as good as same to the arteries and veins through which fluid, vapours, slurries, solids etc. flow under various conditions as imposed by the process design of the plant.
Piping always represents a sizable part of the total installed cost of any process plant. It may run to 20 percent or even more of the entire cost of the plant, including land and buildings.
However Piping engineering is a discipline that is rarely taught in engineering universities but is extremely important for safety of plant, plant personnel, safety of public, and reliability of a facility.
