When a fluid is required to be transferred from one location to other, pipe is required. A pipe is considered as a pressure tight cylinder which is used to convey fluids under pressure through materials of commercially available designation.
A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders, masses of small solids. It can also be used for structural applications; hollow pipe is far stronger per unit weight than solid members.
Piping systems act like a nervous system for the flow of fluid in the huge network of any industry around the globe.
